INTRODUCTION
One might ask, "What is a FAMILY
SCIENCE NIGHT? In the context of this handbook, a FAMILY SCIENCE
NIGHT is an evening program or Saturday program of hands-on science activities
in which elementary school children and their parents can work together.
It is an opportunity for elementary school children and their parent's)
or adult partner to sit side-by-side or across a table from each other
and conduct simple, hands-on, inquiry-based, age-appropriate science experiments.
Though most of the activities can be done on an individual-family basis
at home in the kitchen, this Family Science Night is a more formal one
in which supplies and instructions are provided on tables so that many
children and parents can work simultaneously. Finally, a Family Science
Night as described in this handbook uses readily available materials and
can be conducted at very low cost.
(Some links will not be active
until appropriate Activities and Appendices are completed.)
GOALS
OF A FAMILY SCIENCE NIGHT
The two primary goals of a
Family Science Night are:
-
to stimulate an excitement and
interest in science in elementary school children and their parent
-
to get parents involved in the
educational process
A very important secondary benefit
of a Family Science Night is to generate healthy interactions between children
and their parents.
"Doing science" through
persistent hands-on investigations to solve a dilemma, described elegantly
by V. Manganus, K. M. Rottkamp, and J. Koch,1
is what makes a Family Science Night so special and very successful.
Discrepant events are built into the activities to provide the element
of surprise. A guided discovery mode of teaching is used in the instructions.
Although we are emphasizing science, obviously "doing" is not just applicable
to science. For example, J. S. Chatzky described very recently how
J. Cotterís second-grade class learns about money, interest, banking,
spending, penalties, and responsibility for their own actions through learning-by-doing
daily in the classroom.2
We assume that you are studying
this handbook for planning and conducting a Family Science Night because
you have heard about or seen the benefits of a Family Science Night and
want to present a Family Science Night with a team of other people.
This handbook is designed to help you accomplish that objective.
Besides stating what a Family Science Night is and defining its goals,
the purposes of this handbook are:
-
to give a pedagogical rationale
for a Family Science Night
-
to describe some other family
science programs
-
to indicate how to make contacts
with an appropriate group

for science activities which we have utilized for our Family
Science Nights
-
to describe other sources of ideas
for family science programs
-
to indicate how to develop a Family
Science Night
-
to provide an inventory of materials
needed for the activities
-
to note how and where to obtain
supplies inexpensively
-
to describe ways of packing supplies
efficiently
-
to show how to set up physically
for a Family Science Night
-
to describe a typical Family Science
Night

after a Family Science Night
PEDAGOGICAL
RATIONALE FOR A FAMILY SCIENCE NIGHT
In our past efforts, we have
emphasized the importance of "doing science" rather than just hearing about
it or reading about it in order to stimulate interest and generate curiosity
among elementary school children.3 We
have seen the joy and enthusiasm that results. We have conducted
workshops for teachers so that the teachers might become more comfortable
involving their children in science activities. The next logical
step is to bring parents into the process.
We agree completely with J.
B. McCabe, the editor of Science and Children, who noted earlier this year
that "we are well aware that research shows us that children with parents
involved in their education perform at higher levels than those children
whose parents are divorced from their learning." She says further
that "I am convinced that science activities both in and out of the classroom
provide the perfect vehicle for children and their parents to participate
together."4 Several surveys have conveyed
this same message. Two surveys in 1982 and 1988 indicate that parents
pass to their children their own attitudes toward science and mathematics.5,6
Therefore, it is exceedingly important that we generate enthusiasm and
stimulate curiosity more so in parents even than in the children.
Otherwise, whatever enthusiasm is generated in school will be stifled at
home. In 1992 P. B. Campbell found that women pursuing careers in
science and engineering mention their parents most frequently as a significant
influence in their career plans and that, unfortunately, 20% of the high
school and college women indicated that their parents discouraged their
interest in and study of engineering.7
Moreover, Kober noted in 1993 that parents who were never very good at
science or who fear or are uncomfortable with science may pass those feelings
along to their children, thus prejudicing their children's perception of
the importance of science and how well they can do in science.8
Based on these and similar surveys the U. S. Department of Education mandated
in 1994 that every school will promote partnerships that will increase
parental involvement and participation in promoting the social, emotional,
and academic growth of children.9 In 1995
P. Daisy and M. G. Shroyer found that parents are extremely important components
in the learning of science and mathematics.10
In their surveys 57% of the parents recommended more invitations to after-school
demonstrations and more direct involvement with instruction. One
parent was quoted as saying, "have the children go with parents and let
parents experience what children are doing in science and math."10
It is just as obvious that
determining how to involve parents is not easy. We believe that a
Family Science Night is one way to get parents excited about science and
involved in the education of their children. In spite of comments
to the contrary by principals, teachers, and curriculum coordinators who
ask what is the minimum number of people we need to conduct a Family
Science Night and tell us that they cannot get parents to come out to programs
like this, our biggest problem is often to hold down the crowd. We
can only keep about 80 children and their parents (about 175 total) busy
at one time with our activities. However, we had nearly 300 people
at one Family Science Night last Fall because numbers were not properly
restricted and some were told they could come even in after-school calls
on the day of our visit. Similarly, when parent/teacher teams at
Stevens Elementary School in Burnt Hills, NY set up their own Family Science
Night after our initial visit the year before, as we are wanting you to
do, they conducted the activities three nights instead of the intended
one evening because so many people signed up for the program.
Involving parents in a Family
Science Night is not without its difficulties. Many parents are not
accustomed to a hands-on, guided-inquiry mode of teaching and learning.
Parents frequently find it rather threatening when their children begin
asking or discussing questions which they cannot answer. L. Okasgaski
and R. J. Sternberg emphasized that changing teaching methodology to a
hands-on, inquiry-based mode of learning may confuse and cause resistance
in parents who have learned from textbook and drill sheet memorization
of facts.11 On the other hand, we have
often found the degree of stimulation and excitement in parents to equal
or exceed that of their children.
Plenty of the secondary objective
of child/parent interaction also occurs, especially if we can stay out
of the picture and not be too quick to help out with problems or dilemmas.
At the end of one evening, a father said, "this is the most interactive
time which I have ever had with my daughter. Usually we go to the
movies, we sit in the dark, and we don't talk. Where are you going
to be next week?" Can you relate to that?
OTHER
FAMILY SCIENCE PROGRAMS
A number of people and groups
have tried family science programs in the past, most with great success.
Some are more like a show and are primarily in a demonstration mode; most
of the ones discussed here are of the hands-on, guided-inquiry type.
None are accomplished by a single person though there is usually a strong
coordinator. A few are outlined briefly to give you a sense of the
great variety. P. B. Strawbridge, with the help of high school students,
has held three-hour, Saturday- morning, hands-on science sessions for 5th
grade children and parents.12 F. L. Holmes
has also offered a Saturday morning program.13
V. Parker has coordinated a Saturday-morning science festival of 60 hands-on
activity tables in a schoolyard.14 C.
Renkas has developed a weekend program in which community experts guide
a series of hands-on programs at different locations.15
D. Weissman has even described a Friday night slumber party for children
and parents with activities emphasizing science.16
D. H. Gardner has organized family science programs during regularly scheduled
school-year events.17 J. C. Fehlig has
trained a team of parents to lead hands-on science activities during the
school day.18 J. Swim has trained high
school students to lead hands-on science activities in elementary schools
during the school day.19 L. H. Barrow,
N. Knipping, and R. Litherland have used problem-solving science activities
on weekday evenings20 as we have done.
Hands-on science activities are not just for school;21
in fact, some parents are uncomfortable visiting schools but willingly
take their children other places. M. G. Jones has described a program
emphasizing literacy and cultural diversity through science activities
held in churches, community centers, or museums.22
D. McCreedy, M. Borun, H. S. Mosatche, and K. F. Wagner have described
an effort which is fully museum based.23
One type of community outreach program conducted by M. C. Sherman consists
of seven evening programs during the school year for 5th through 8th grade
students and parents or other hearing partners at St. Joseph Institute
for the Deaf in St. Louis, MO.24 Finally,
M. Tinnesand and D. Creech have set up a program through the American Chemical
Society to train scientists to conduct hands-on science programs25
just as we are trying to do through this handbook.
MAKING
CONTACTS TO SET UP A FAMILY SCIENCE NIGHT
Many of you were already designated
as members of teams being trained to conduct Family Science Nights in a
particular school. Your principal or science coordinator knows about
your training and will probably contact you. The principal may, however,
need a reminder. This contact will be the stimulus for you to get
your team back together, make specific assignments, decide what activities
you will use, obtain supplies, and conduct the program.
Others of you were a part of
workshops where you have been trained, but may come from industry, government,
libraries, museums, or other agencies rather than representing a specific
school. Networking through coworkers, friends, and family with elementary
age children is the best way to advertise your willingness to conduct a
Family Science Night and to make initial contacts with schools. It
is useful to have a single-page description of your objectives, how you
would like to accomplish them, and what help you will need (see APPENDIX
A
for a sample which you should modify to fit your program). Give this
description to your initial contact so that person can take it back to
teachers, the science coordinator, or the principal to obtain permission
to hold a Family Science Night.
If you prefer to conduct a
Family Science Night at a library, museum, Boy Scout meeting, Girl Scout
meeting, 4-H meeting, family reunion, county fair, church youth group,
playground, or in whatever context, contact the appropriate leader directly
with the same description noted above.
Once you have conducted your
first Family Science Night, you will probably not need to do further advertising
or make additional contacts. Word-of-mouth through the grapevine
will accomplish this for you, whether you like it or not. A parent
who brought a child to your first program may also be a teacher at another
school and pass the word. The word will also be passed at the next
teacher in-service session. Another parent who brought a child to
your first program will be the program coordinator at a local library or
museum and will tell coworkers. Your most difficult task after this
will be for you to gracefully say "NO" on some occasions!
However your contacts are made,
consult with each school organizer to set a date; provide material for
advertising (see sample copies in APPENDIX B); give guidance concerning
physical layout and needs such as water, sound system, and trash barrels
(see Setting Up the Space
for a Family Science Night); and discuss possible impediments such
as after-school activities in the cafeteria during a time that your team
needs to be setting up. Even a principal easily loses track of all
of the after-school activities held in the cafeteria without a reminder
to check them. If you are working outside of a school setting, some
of your needs may be even less well understood and must be specified clearly.
POSSIBLE
ACTIVITIES FOR A FAMILY SCIENCE NIGHT
Ready-to-use instructions for
more than 20 activities which we utilize regularly at Family Science Nights
are provided under the List
of Activities. They are in alphabetical order by the titles.
You can print those pages directly. They are about 90% of the size
that we normally use. You may want to enlarge them when you copy
them for your use. Any number of copies of these instructions may
be made for educational use, but copies of the instructions may not be
sold for a profit.
Liability Disclaimer
We have made every reasonable
effort to phrase these instructions carefully in order to point out obvious
safety precautions and to encourage safe experimental practices, safe use
of equipment and supplies, and proper disposal. However, we do not
pretend to have addressed all possible risks and safety problems associated
with the substances and equipment or the methods prescribed for their use.
It is the responsibility of the persons using these activities to study
labels on containers and Material
Safety Data Sheets where provided; to consult and comply with pertinent
local, state, and federal guidelines; to see that parents or adult partners
supervise their children carefully; and to practice reasonable care and
common sense in the execution of these activities. Moreover, we cannot
assume responsibility for mishaps that occur whether or not the instructions
were followed rigorously by children or their parents.
Even water is a hazardous material
if it is spilled on the floor and someone then slips on it and falls before
it is mopped up. We strongly encourage all those planning to use
these instructions or instructions from other sources to modify or augment
the procedures, if necessary, in accordance with your common sense, your
needs, and accepted local codes and practices. Precautions for the
safe use of chemicals and directions for their proper disposal are on the
labels of containers or on Material
Safety Data Sheets obtained upon request at the time of purchase.
An example of an MSDS for sodium bicarbonate (baking soda) is provided
in APPENDIX C.
We have chosen not to have
children or parents wear safety glasses or goggles since we only use chemicals
that can be purchased in the grocery store. You may decide that your
local practices dictate a different guideline. Are there hazards?
Certainly the answer is YES. For example, horseradish may be used
as one of the samples in our Starch in Food Products experiment, and vinegar
may be used as one of the samples in our Acid-Base Behavior of Kitchen
Chemicals experiment. Do you wear safety glasses or goggles when
you serve or eat horseradish or when you prepare and shake a vinegar salad
dressing? In one sense you should because both horseradish and vinegar
burn significantly if you accidentally spatter some into your eye.
We have decided to accept this risk, but know that you should rinse the
eye vigorously with water for ten minutes if either of these accidents
happens.
OTHER SOURCES OF ACTIVITIES
FOR A FAMILY SCIENCE NIGHT
Many of the references cited
earlier provide activities that, with expansion of the procedures but otherwise
little or no modification, are appropriate for a Family Science Night.
There are, however, many book sources that provide more activities in one
place and usually with detailed instructions including purpose, procedure,
materials required, and a brief explanation. Some of the books which
we have found most useful for work with elementary school children are
listed in alphabetical order by authors (where appropriate) in Book
Sources of Hands-On Activities under Other Resources. A few merit
special comments.
If you attended one of our
workshops, you or another member of your team received a paperback copy
of Kessler and Barrett, The Best of WonderScience, which is one
of the most extensive sources. It presents more than 400 activities
covering primarily chemistry and physics and should provide you plenty
of activities from which to choose unless you get into Family Science Nights
as your profession. It is in full color and has detailed instructions.
It is a compilation of the first 10 years of WonderScience magazine
for those of you who know that magazine and is also geared to the National
Science Education Standards. The activities are designed for grades
four through six, but we have used some them from kindergarten through
8th grade with only a few modifications. It costs over $50 and can
be obtained from Delmar Publishers, 3 Columbia Circle, Box 15015, Albany,
NY 12212-5015 if you want additional copies. During this past year,
the second edition of The Best of WonderScience has been published.
It is presently reviewed under Book
Reviews.
The set of books by Janice
VanCleave is excellent. There are also four other ones covering Ecology,
Geography, Geometry, and Math. You can purchase them by topic depending
upon your needs through a local bookstore. Their greatest strength
in our judgment is described by some of her subtitles (101 experiments
that really work). The great variety of activities are
well tested, and anyone can conduct the activities from the simple instructions
provided. One weakness of these books is that the explanations are
very brief if you need detailed background to bolster your confidence.
These books are a great bargain at $11.95 each in paperback. She
has also written at least nine books in a Spectacular Science Project series
covering Animals, Earthquakes, Electricity, Gravity, Machines, Magnets,
Microscopes and Magnifying Lenses, Molecules, and Volcanoes. These
are particularly useful for science fair projects.
The book by Friedl, Teaching
Science to Children: An Integrated Approach, is just the opposite of
the VanCleave set in terms of providing very detailed explanations and
background material. Each section contains combined discussions of
both procedures and content. Friedl is also a master at taking a
simple activity and building in the element of surprise, creating that
discrepant event. In our experience this markedly increases student
interest and motivation. This book presents more than 300 activities
and costs about $43 (but is now out of print).
The books by Liem, Invitations
to Science Inquiry and a Supplement, present more than 450 activities
between them. They are designed primarily for the upper elementary
and middle school levels, but we have adapted some of them for the lower
elementary grades. As in most of the other books described, each
activity is illustrated with a list of easily obtained materials required,
a sketch of the experiment, a step-by-step procedure, what questions to
ask, and an explanation. Many activities are set up as discrepant
events. The main book is about $45 through a local bookstore.
The most significant strength
of Super Science Connections is its integration of appropriate children's
literature with the hands-on science activities. It does this more
effectively than any other books that we have encountered. This aspect
is probably more useful to teachers in the classroom, allowing them to
use time more efficiently by combining language arts and science, but the
book also has some good activities for Family Science Nights. It
can be obtained from the Institute of Chemical Education for about $32.
A list of book sources for
activities for middle or even high school children is provided Book
Sources of Hands-On Activities. Some books are on both the elementary
and middle school lists. Especially the new entries by Borgford and
Summerlin; Humphreys; Shakhashiri; Summerlin and Ealy; and Summerlin, Borgford,
and Ealy offer generally more sophisticated experiments that often require
considerably fancier equipment, much more stringent safety precautions,
and older children under stricter supervision performing the experiments.
Finally, ideas or complete
hands-on activities can also be found at many sites on the web. A
few web sites that we or others have found useful are listed under Web
sites. Watch the links from these to other sites as well.
Also take the time to do some of your own surfing; there is a wealth of
activities on the web if you can only find them.
HOW TO DEVELOP A FAMILY
SCIENCE NIGHT
The two most important principles
are
-
Don't try to do it yourself; work with a team.
-
Keep it simple, especially the
first time.
Developing a Family Science Night
requires a few heads and many hands. One person can pull together
enough ideas, but there is a greater variety of ideas if several people
are involved. The sheer time required to find an appropriate activity,
try it and modify it to your situation, accumulate the supplies, pack the
supplies, and then set it up and pack it up on the night of the program
means that initially, if you have this luxury the first time, it is helpful
to have one person responsible for developing each activity or two activities
at most. Obviously, the task is easier if you are using activities
that have already been developed for this purpose by someone else.
Once you have a set of instructions that make sense for your situation,
this development phase is essentially completed except for minor modifications
and improvements. Even after all of our practice, we can't imagine
developing and conducting a Family Science Night alone.
There are several ways of keeping
the development simple. First, start with a small number of activities,
and use more stations of those activities. It is much easier to develop
one activity and to obtain, pack, and set up supplies for multiple stations
of that one activity than it is to develop multiple activities. What
is the minimum number of activities needed? Assuming that parents
are helping to hold their children on a task and to face at least some
of the questions posed (sometimes wishful thinking), most activities will
require a minimum of ten minutes to accomplish. Thus, children and
parents will complete no more than five or six activities in an hour.
In reality, some children will jump from one activity to the next with
parental concurrence and will try more than six activities. In any
case, six activities is probably an absolute minimum. We now set
up 15-20 activities for most of our programs, depending upon the space
available and the number of people expected. Nobody completes nearly
all of the activities, but that is as it should be because you want them
to be excited about coming back again and about trying some of the activities
with parents at home.
A second way to keep the development
simple is through a careful choice of activities. Especially if you
are choosing new activities, keep in mind a number of considerations: safety
factors, age-appropriateness, space required to perform the activity, ease
of obtaining supplies, the number of different supplies required, whether
the supplies can be recycled or reused, the cost of supplies, and the ease
of packing the supplies.
A third way to keep the process
simple is to limit the number of children and parents at the Family Science
Night. This can be done in many ways: limiting participation in the
program to one grade level, taking sign-ups on a first-come-first-served
basis, taking sign ups of interested people and then choosing participants
by a lottery system, or some combination of these. We usually also
have to consider space available which frequently dictates that each child
have only one parent or adult partner, not necessarily a desired
situation. Moreover, you must consider whether you can afford the
luxury of encouraging parents to perform an activity simultaneously across
the table from the child with discussion of similarities and differences
following or whether you must encourage the child to perform the experiment
with occasional guidance and discussion from a parent looking over the
child's shoulder. To some extent, the child and parent will function
and interact in the way that they are comfortable anyway! However,
you may find that interaction increasing gradually during the course of
the evening. We sometimes have to make a last-minute decision on
how to phrase this encouragement in the introduction of the program when
we hear from the organizer how many to expect or see the crowd in front
of us.
Combining the ideas in this
section, six activities with eight stations each can accommodate up to
40 children and their parents with some spaces to which they can move after
completing an activity. You can then enlarge this program as needs
require and experience allows.
EQUIPMENT
AND SUPPLY LIST FOR A FAMILY SCIENCE NIGHT
To keep track of equipment
and supplies on hand and/or needed for our next Family Science Night, we
have developed an "Equipment
and Supply List. This list was developed for a Family Science
Night for 75 children and a parent or adult partner - 150 people
in all. If a spreadsheet format is used, changes to the list can
easily be made as you add, drop, or modify experiments. This list
is organized according to the experiments we set up, showing specific supplies
and quantities of those supplies needed to do that experiment. The
experiments for the Opening Demonstrations are listed separately for convenience
and because they may change more frequently than the others. Because
each experiment is basically packaged separately (see Packing
Supplies for a Family Science Night), each one can quickly be checked
to be sure all of the necessary supplies are in the appropriate bag.
In the "Get" column we place a check mark if the needed item is fully accounted
for. If supplies need to be replenished, we note how much needs to
be purchased. Once an experiment bag either contains all of the needed
supplies and supplies too large for the bag are accounted for, the experiment
is checked off in the margin of the list.
At the end of the list, there
is an "Extras Box" category. We have learned that it pays to "be
prepared," and keep some extra supplies with us at all times. Although
not on this list, we also keep balloons, cups, markers, scissors, extra
bottles of glue, etc. with us so that if more people show up than planned
and table space is available, we are able to "expand" the program somewhat
to handle some extra people. Several experiments are very easily
"expandable." For example, just by placing two extra pairs
of scissors on each of the tables for Canned
Constellations, Faster
Than the Eye Can See, and Wonderwhirler,
you can accommodate 6-18 more people, because the experiments do not require
the constant use of a pair of scissors. Also, there are evenings
when one experiment seems to capture the attention of the participants,
and the supplies for that experiment run out before the program ends.
Often, we choose to just let that happen and close out the table early;
however, at other times, we put extra supplies out so that more people
can participate in that experiment. This decision depends mainly
on the time left for the program, whether the same people have done that
one experiment many times over (such as often happens with From
Glue to Glob or Invincible
Balloon), or whether there are several interested people who have not
yet had a chance to do that particular experiment.
OBTAINING
SUPPLIES INEXPENSIVELY FOR A FAMILY SCIENCE NIGHT
Shopping for a Family
Science Night program is quite simple, because the supplies needed are
simple. Most of our supplies can be obtained at a local grocery store
or grocery warehouse, "KMart"/ "Walmart," and/or paper supply store such
as "Staples" or "OfficeMax." There are a few items which we obtain
through science
supply catalogs. To help you get started, we thought it would
be helpful to give you some hints we have found useful when obtaining supplies.
Acid-Base
Behavior of Kitchen Chemicals: The Indicator strips (approximately
1/4" x 5") are cut from sheets of Goldenrod (Galaxy Gold) paper obtained
from "Educational
Innovations, Inc." If you purchase the Galaxy Gold paper from
"Office Max" and other local paper stores, take a container of Windex with
you and ask to test a sheet of the paper before you buy a ream. If
it doesn't turn red when sprayed with Windex, Wausau Paper Company has
changed the dye in your part of the country, and the paper will not work.
Attractive:
We keep trying to "beef up" this experiment and have recently added a pile
of magnetic marbles and a stack of five ring magnets on a stick so the
children can observe and play with magnetic opposing/attracting forces.
The marbles are available at toy stores, and the ring magnets are quite
inexpensive at "Radio Shack."
Canned
Constellations: Film developing centers are usually happy
to give you the film canisters they would otherwise discard. Black
canisters are needed for this experiment, as the white opaque ones let
in too much light for the pin hole patterns to be seen.
Cartesian
Divers: 4" glass-tipped medicine droppers enable the child
to see clearly the change in water level. However, most of the droppers
we've seen in pharmacies are too long or are translucent plastic.
"Educational
Innovations, Inc." has plastic pipets and brass nuts available for
a reasonable price for you to construct your own divers.
Center
of Gravity: We use several pieces of irregularly shaped,
sanded, scrap wood, with the sharp edges rounded off. The "balancing
bird" was purchased at a dollar store. The map of the USA (contiguous
states) was in a travel/map book. We copied it, laminated it with
sheets of laminating plastic (bought at "BJ's," the food warehouse), and
then cut as close to the contours of the U.S. as possible so the children
can obtain a fairly accurate center of gravity. It is about 6" x
4" so it is easy to balance on a pencil eraser.
Chromatography
Mystery Note: A black Vis-à-Vis pen gives the best
color separation of all the water-soluble markers we've tried. If
filter paper is not readily available, you can use coffee filters or even
paper towels, though you should experiment with the towels ahead of time
to find out which kind works best. We laminated the mystery note
chromatographs with sheets purchased from "BJ's" (see Center of Gravity
above). Squeeze bottles may be obtained from "Fisher
Scientific, Inc." or you could use plastic catsup/mustard bottles.
This activity provides a good
example of the evolution of an experiment. We began with unbleached
muslin squares stretched over empty tuna fish cans, using permanent ink
markers and alcohol-filled droppers to obtain a prettier permanent separation
of colors. However, when the non-washable inks permanently stained
a school's new lunch table, we quickly changed to water-soluble markers!
To make life easier for ourselves, we changed next to filter paper instead
of cloth, and "beefed up" the activity by providing a mystery for the children
to solve as part of the instructions.
Dissolving
and Reaction of Alka-Seltzer: Thermometers are obtained from
"Delta
Education."
Empty
the Bottle: The five-pint glass bottles that we use have
what is called a Safe-Cote for safety reasons. This plastic coating
over the glass prevents the glass from breaking apart in case the bottle
is dropped and broken. These bottles can be obtained from a local
high school, college, or university where they are often discarded after
the original reagent is used. The alternative of using a plastic
bottle is not as effective because the children get excited and squeeze
and collapse the plastic bottle while trying to get the water out.
The glass bottle holds its shape. You can make a glass bottle safe
in the same fashion as the Safe-Cote by taping it on the outside.
Transparent, wide, Scotch strapping tape is best because it will stick
for a fairly long time even when wet providing it is taped over itself
in a number of places. However, the children can still see through
the bottle.
Faster
than the Eye Can See: We drill the holes in the poker chips
at home, using a 1/16" drill on a drill press. Using a regular hand
drill can prove to be frustrating, as it is difficult to hold the poker
chip steady and the drill tends to clog with plastic. Without a drill
press, we would redesign this experiment, but try to keep it because it
is instructive and quite popular.
From
Glue to Glob: We usually buy Elmer's Glue-All by the gallon
and wash and refill the 7.6-ounce plastic squeeze containers after each
Family Science Night. This works all right if you are working out
of your own home, school, or laboratory and don't have another program
for at least a few days or weeks. However, if you must conduct a
couple Family Science Nights in the same week or don't have a convenient
place to wash these sticky bottles, pay the extra cost, buy the glue originally
in the 7.6-ounce containers, and start with new containers for each program.
Invincible
Balloon: One summer, while in Kansas, our host coordinator
was unable to get to the nearest Walmart - 150 miles away.
Instead, she ordered balloons from a local florist. They were lovely
balloons, but we soon realized that every single one was "popping" during
the course of the program. While there are always some balloons which
pop, many should stay inflated when the skewer is poked in. On closer
inspection, we realized that because these were very high quality balloons,
they didn't form a darker-colored "nipple" opposite the mouth of the balloon
when it was inflated. Thus, there was no extra unstretched rubber
in that area for the skewer to maneuver through, and the balloons all popped.
Moral of the story - buy the cheapest balloons available!!
We get ours at "Kmart" - 144 for $5.98. People tend to
use too much Vaseline on their skewers, resulting in a very greasy table
by the end of the evening. Clean-up is much easier if newspapers
are put down before placing the supplies on the table.
Iron
in Breakfast Cereal: It is very easy to see the gray-to-black
iron filings obtained from the cereal using a white stirring-bar magnet.
We purchase ours from "Fisher
Scientific, Inc." and then put them into a 5" piece of Tygon tubing
to form a handle. However, you could paint the magnet on a less expensive
magnetic wand with white acrylic paint and achieve a similar result.
Perception:
Remember that some of these pages must be in color. We had these
pages laminated professionally in order to have more durable sheets.
To keep them neat we then punched holes in them and placed them in a separate
binder.
Soda
Bottle Symphony: Glass soda bottles are becoming extinct!
However, there are still lots of glass bottles around - the
important issue is to have four bottles of the same shape and size so that
the children can see the changes in water level as they listen to the changes
in pitch.
Starch
in Food Products: Iodine from a local pharmacy is diluted
approximately 1 part iodine:30 parts water, or one dropper-full of iodine
in one film canister of water.
Swinging
Pendulum (Length) and Swinging
Pendulum (Mass): If ring stands are not available, you could
make a stand - about 30" high, or hang the pendulum from a
low ceiling, from a doorway, or from a table.
Weighing
Pennies: If your school does not have a sensitive enough
beam balance, you may be able to borrow one from a local high school.
The electronic balance is nice, but very expensive, and the beam balance
by itself is sufficient for the children to get a good reading on penny
weights.
Wonderwhirler:
One former workshop participant, who has done a lot of work in his local
elementary schools, found that even his children, who have done this experiment
a number of times, really got excited when he used brightly colored paper
instead of white paper.
PACKING SUPPLIES FOR A
FAMILY SCIENCE NIGHT
One thing of which we are aware
is the lack of storage space in homes and in classrooms, with the result
that it is difficult to find things when needed! However, if each
experiment can be placed into its own bag, finding an experiment you want
to do becomes less of a hassle. We are very thankful for plastic
zip-close storage bags as they readily provide the required organization.
We put all of the items needed to do a specific experiment into one bag,
and then label that bag with the name of the experiment. However,
to keep the papers neater, we do not put the instructions or patterns in
the bags. Different experiments are packed into different sized bags
according to need. For example, in the bag labeled Wonderwhirler
(a quart-size bag), we will have 6 pairs of scissors and a box of paper
clips; in the Dissolving
and Reaction of Alka-Seltzer bag (1-gallon size) there will be 4 plastic
beakers, 4 thermometers, and a box of Alka-Seltzer tablets; all of the
items listed under the Center of Gravity experiment on the "Equipment and
Supply List" are in the Center
of Gravity bag (a 2-gallon bag); and a pint-size bag contains the pendulums
wrapped around cardboard whereas the ring stands are accounted for separately.
Once all of the experiments have been set up, we distribute instruction
sheets for all of the activities; the patterns for Canned
Constellations, Scale
Model of Our Solar System, and Wonderwhirler,
and graphs for several experiments to the appropriate tables. We
also place pencils where needed.
There are a couple of experiments
which require equipment or supplies which will not fit into even the 2-gallon
bags, so those are packed separately. Chromatography
and From
Glue to Glob are packed into one box, and one tote box is designated
for Cartesian
Divers and Empty
the Bottle. Obviously, the ring stands and meter sticks are also
separate from the other supplies. The 2-liter soda bottles and 1/2-gallon
containers for waste water or cereal slurry are usually packed in our "Extras
Box," as is the "Total" cereal. Once a bag is packed and checked
on the "Equipment
and Supply List," we place it in a 12-gallon plastic tote box (we bought
ours at "BJ's" for $4.00, including the lid). We often make a list
of which experiments go into each tote box and tape it to the lid so that
we know where to find specific experiments if needed.
The tote boxes stack neatly
on top of one another, so if you can find a corner in your storage area,
the inventoried and fully supplied boxes can be stored away until the next
time they are needed.
SETTING UP THE SPACE FOR
A FAMILY SCIENCE NIGHT
Family Science Nights are normally
held in a school cafeteria which is most appropriate because there will
be minor water spills that will not be good for a hardwood gym floor or
rugs in a library-type space. However, we have conducted Family Science
Nights in gyms, cafetoriums (combination cafeteria, auditorium, and sometimes
gym, usually having concrete floors), libraries, museums, community centers,
fire halls, armories, county fair buildings, church halls, and probably
other places. You have to be flexible and work with the spaces that
are available. We have occasionally not used a couple of activities
depending on the nature of the space and the inconvenience of spills.
Tables and chairs are set up
ahead of time by janitorial or custodial staff. An ideal table arrangement
is shown in APPENDIX F
in that there is space between tables for easy movement and there is an
open space at the front demonstration table for children to sit on the
floor during short opening demonstrations. Normally tables should
have more space between them than is the usual case for school lunches
to allow easy passage of people between tables. Again you must be
flexible and make do with what is available. For example, some schools
have double folding tables locked to facing walls in the cafeteria so that
making additional space between tables is not possible. With some
activities, you may not want to set up on both sides of the table if you
can't achieve additional space between tables. The number of tables
is determined by the size of the space and the number of people you want
to accommodate. About 20 seven- to eight-foot tables with seats or
chairs are required for about 150 people. You can factor up or down
from that number depending on the expected crowd. We also use one
table (which can be the demonstration table during the opening, if necessary)
for laying out book sources that parents can look through or printed materials
such as Finding
Constellations that you want families to take home. These can
also be laid out on a stage if that is adjacent to the space.
Several trash barrels and a
close source of water (preferably hot and cold for Dissolving
and Reaction of Alka-Seltzer) are also necessary. We ask schools
or other groups to provide newspapers to cover at least two tables on which
From
Glue-to-Glob and Invincible
Balloon will be done. This makes clean-up much easier at the
end of the program. We also ask that several rolls or packs of paper
towels be provided so that spills can be cleaned up quickly. Empty
the Bottle is obviously set up close to the source of water so that
tubs of water don't have to be carried very far. Dissolving
and Reaction of Alka-Seltzer is set up close to the source of hot and
cold water. Most schools will let organizers obtain water from the
kitchen adjacent to the cafeteria or from a janitor's closet but often
require parents and children to get hot or cold water from a lavatory because
they are not wanted in the kitchen or the janitor's closet. Certain
experiments cannot be placed on adjacent tables that are locked together
through a folding mechanism. For example, Invincible
Balloon causes sufficient excitement that the table is jarred constantly
and would prevent the stabilizing of balances used for Weighing
Pennies on an adjacent but connected table. We have three experiments
that utilize pennies. They should not be set up near each other because
the pennies will get mixed up, and the pennies in the Weighing
Pennies experiment have to be from certain years. We do not try
to set up the same arrangement of experiments at each site because there
are simply too many variables to consider on the spot. However, you
will usually know the configuration of your site ahead of time.
Normally it takes two of us
a little over an hour to lay out supplies and instruction sheets for about
20 activities for 150 people. That time can be reduced if several people
are each responsible for a couple activities. Remember that setting
up must also be accomplished while most people are eating dinner so that
earlier or other arrangements must be made for dinner. Some schools
arrange for box suppers that we can eat at any convenient time during setting
up.
As described earlier under
Packing
Supplies for a Family Science Night, most of the supplies for each
experiment are contained in a single zip-close bag. Thus, bags are
laid out first on appropriate tables; contents of bags are then distributed
onto each table; bags are collected for later repacking; water containers
are filled where necessary; instruction sheets, patterns, and graphs (which
have been previously alphabetized with appropriate numbers of copies) are
placed at each table; and pencils are distributed where needed. You
hope all this happens before people come charging in! But learn to
be flexible. At one school, I had to start the Introduction in the
library and demonstrate longer than planned while a basketball game was
being completed in the gym after which custodians set up tables while Priscilla
and the assistant principal set up the stations so that we could move into
the gym!
DESCRIPTION OF A TYPICAL
FAMILY SCIENCE NIGHT
When people arrive, we and
the coordinators tell them to sit wherever they want but not to start any
activities until after the Introduction. Generally, the children
follow this instruction very well, but some parents may need periodic gentle
reminders.
At the starting time, we gather
the children at the front for the Introduction, facing the demonstration
table. Parents remain seated at the tables. Sometimes we are
introduced; sometimes we have to introduce ourselves. It helps to
ask the coordinator ahead of time so that at least you know how to handle
the situation.
With help from children who
volunteer from the audience, we present several brief demonstrations.
These demonstrations generate enthusiasm, introduce several activities
which children and parents will perform later, and set the tone for the
evening. Injecting a little humor and the element of surprise certainly
makes the demonstrations more stunning and raises the excitement level.
For example, we may perform The Invincible Bag experiment by having a child
hold a zip-close bag filled with water while we try to push a pencil through
the bag to illustrate some of the principles involved in a later activity
in which children try to push a wooden skewer through a balloon without
puncturing it. The audience is expecting the child to get wet throughout
the experiment, but, of course, it never happens because the zip-close
bag seals around the pencil and prevents water from leaking out.
During the Introduction we
also describe how children will work with their parents at their own pace
and move from station to station during the evening. We note that
some activities yield products that can be taken home and that these are
specifically marked on the instruction sheets. We also remind them
not to remove any other items from the tables (and particularly wooden
skewers which should not leave the table for safety reasons as well), or
supplies will not be there for the next persons. We urge parents
to involve children with the questions that are raised on the instruction
sheets and prod children and parents to graph data where requested.
We point out the book table where parents can look at materials that they
might purchase for use in the home and remind them a take a two-page copy
of Finding
Constellations (see APPENDIX G,
in case parents don't know how to find the constellation in the night sky
that matches the child's Canned
Constellation). Finally, we thank all sponsors and individuals
who have helped to make the evening a success before sending children back
to work with their parents. The Introduction normally takes about
20 minutes.
During the next hour children,
with occasional assistance or direct help from a parent or adult partner,
perform many of the activities at the tables. None will have time
to do all of the experiments. During this time Priscilla and I, who
are very evident in our colorfully decorated white laboratory coats, move
through the crowd. One of our roles is to obtain additional supplies
if they are needed or to locate supplies, if possible, that allow child
and parent to try something which they have devised. If we are asked
questions, we try to raise other questions that will encourage the child
and parent to seek their own answer. For us at least, it is more
important that the child and parent communicate meaningfully with each
other than it is that the science be exactly right. This is a very
important principle because we have found that if there is an authority
figure at each table prepared to answer any and all questions, most interaction
between child and parent ceases since it is easier to ask the authority.
This period is one of noisy excitement, but if it is well planned, it almost
runs itself.
At the end of the evening we
usually have a ten-minute Closing session during which we discuss a couple
of activities in more detail or show how they might be done more efficiently
and effectively. We often choose which ones based on the number of
questions we were asked about an activity during the evening, observations
we made which showed that people were doing an activity incompletely or
without understanding what they were doing, or any other criteria.
Even though people beg, don't
let the program drag on. You want them to leave with a desire to
do more, and many of them are too young to stay up later with school again
the next morning.
Some parents ask for copies
of the activities. We do not provide these on the spot. However,
after checking this out ahead of time with the coordinator, we tell parents
that the coordinator has a master copy and can provide a set of instructions
to parents who send a note (perhaps for the cost of copying or frequently
free of charge). Eventually anyone will be able to print our
activities from this Web site.
We ask that a couple of parents
remain afterwards to help clean up, but you should resist the temptation
to accept the assistance of others beyond your trained team. Other
parents mean well, but they will throw things away that you want to save,
they will not pack things the way you would do it, and it will save you
time that evening at the expense of much more time reorganizing the next
day or a few days later.
HINTS
FOR CONDUCTING A FAMILY SCIENCE NIGHT
Following are hints which provided
solutions to problems that we have encountered with our programs or which
others have suggested while participating in our programs or conducting
their own. They are listed rather randomly.
(1) Be very careful to specify
the number of people that you can handle given the facilities, and call
the coordinator periodically to make certain that the school or other group
is holding to that number. The program is suddenly out of control
if you have planned and set up for 90 people and 140 arrive! It will
be overcrowded, you can't keep them all busy at one time, there isn't space
anyway, and some will go home disgruntled about science.
(2) Depending on your ability
to project your voice, the acoustics of the space used, and the number
of people expected, a microphone may be very helpful for the Introduction
and the Closing. We don't like to be tied to a microphone and lose
our freedom of movement, but sometimes it is absolutely necessary.
You should check this out ahead of time with the coordinator. Some
places even have roving microphones that work very effectively.
(3) You will occasionally encounter
over-aggressive parents. Parents are just as wide-eyed and excited
as children at these programs. They may just get so excited about
science for the first time in their life that they are out of control.
Sometimes we have to remind them to slow down and give their child a chance!
Alternatively, occasional parents see this as an opportunity to show their
child how much they know and how important they are. A gentle "cool
it, and give your child an opportunity to do the experiments" generally
solves the problem. Remind them that this program is primarily for
the benefit of the child.
(4) You will also encounter
wayward parents who stand at the side of the room talking to other parents
about the football game last week or whatever while their children struggle
by themselves. Again a gentle reminder that they should be working
with their children may help. Some might be obstinate and hard to
change on the spot.
(5) Try not to answer questions
directly. Rather, ask further questions to steer the child and parent
in a direction that will allow them to answer their own question.
You convey a very important principle about how science works when you
raise more questions for them to think about. Moreover, you may stimulate
evenings of activities at home and a child and parent really communicating
and interacting for the first time in their lives.
(6) If baby-sitting is too
costly or hard to find for some parents, enlist the services of a high
school service club such as Key Club to provide baby-sitting for very young
children. These members are often seeking to fulfill their service
hours, and this allows parents and children to come who could not otherwise.
Similarly, if a single parent has more than one child who could attend
the Family Science Night, it is very difficult to be working and interacting
with more than one child simultaneously. Again, enlist high school
students from service clubs to act as adult partners for the evening.
They will also learn much from the experience.
(7) Parents, and even some
children, in inner-city schools may not read English very well, but may
read Spanish easily. The need then is for instructions in Spanish
as well as English. We presently have a handwritten Spanish set,
translated by Michelle Delamaine in Lancaster, PA, and can provide a copy
of them with sufficient notice. At some later time we may even have
them typed!
(8) A number of people have
asked for more pictures on our instructions to help those who don't yet
read very effectively. Being the super artists and camera bugs that
we are, that is happening only very slowly. However, please feel
free to add pictures or diagrams to our instructions, and we would appreciate
also being able to have copies and benefit from your efforts.
(9) Some people have indicated
that the Purpose section of our instructions is too brief and that more
needs to be said about why a given activity is important and what are its
applications. Others want more follow-up questions which children
and parents can discuss later. Again, feel free to supplement our
instructions. One of our overriding goals has been to keep the instructions
to a single page wherever possible because we have found that it is hard
to get some children to stick with what we have. Nevertheless, use
your own judgment and talents.
HOW TO PACK UP SUPPLIES
AFTER A FAMILY SCIENCE NIGHT
The most difficult part of
clean-up time is politely saying "No, thank you!" to many offers to help
clean up. One night, following a program to which 250 people came,
several people pitched in to help us clean up, and we were out of there
in 1/2 hour. They were wonderful, and very proud of the rapid clean
up. Unfortunately, they were not with us the following two days as
we inventoried materials for many extra hours, due to the mixing-up of
experiments in bags, items thrown away, etc. Ideally, you will have
a committee with whom you are working who understand the packing and inventory
process so that as they pack, it is done in such a way as to enable the
inventory for the next program to proceed much more quickly.
To help the packing up process,
on each experiment bag, we tape a list of the items which should go into
that bag following the program. For example, on the "Canned
Constellations" bag is listed: 3 permanent ink markers, 6 pairs of
scissors, push pins, and film canisters. Thus, whoever packs knows
that 3 markers and 6 pairs of scissors go into that bag. If there
are extra markers or scissors on the table, they are to be left in a separate
pile. They are also aware that the push pins and the remaining unused
canisters go into this bag, but do not have to be counted. Then,
when we inventory that bag for the next program, we can quickly see if
there are sufficient push pins, note that there are 3 markers and 6 pairs
of scissors, and add the appropriate number of canisters.
Using newspapers on the tables
for From
Glue to Glob and Invincible
Balloon is very helpful. However, be sure that someone very familiar
with those experiments is in charge of cleaning them up, as items can easily
get lost in disposing the newspapers. We always have a plastic grocery
bag with us to clean up From
Glue to Glob and put all of the items which need to be washed off into
that bag - including markers, wash bottles, and glue bottles, because we
find it easier to clean them at home than to do so at the end of the program.
If there are experiments no
longer in use near the end of the program, we begin to clean up those tables
early. You will find that even when the program is over, some children
and some parents will continue to work at an experiment. We usually
let them continue for a time if there are other experiments to put away.
However, when that table needs to be cleaned, we let them know that the
evening is over and if they want to continue, they will have to do so at
home.
The experiment bags are then
packed into our "BJ's" tubs, placed into the back of our van, and once
again, we are grateful that another evening program of science activities
provided much fun, considerable excitement and stimulation, some knowledge,
and lots of good interaction for many children and their parents!
SUMMARY
Overall these Family Science
Nights accomplish far more than we could have imagined. They generate
a passion for science in elementary school children, they involve parents
as teachers and learners in the educational process, they provide positive
educational experiences and powerful interactions between children and
parents, and they meet a national goal of getting the general public involved
with and excited about science. Try one, and see for yourself!
