Collection of science ideas - LongHere are lots of ideas collected from the ece mailring, chatboard,& off the internet. Some of the names of the original posters have been accidentally omitted.
Another fun magnet challenge is to put a small magnet in a
plastic water
bottle(filled with water.) Have the children try to move the
magnet through the
water until it reaches the top. --Gail :-)Magud wrote:

>>>Here's a super sink and float "challenge" for the kids.
Give them a
>>>meatball sized piece of plasticine(modeling clay) and a
bowl of water.
>>>Ask them what they observe. They will notice that the clay
sinks to
>>>the bottom. Then ask them if they can do something so that
the clay
>>>floats. Mold the clay into a boat and it will float!!!!!!!THEN - give them paper clips - and see HOW MANY clips they
can float on
their
"barge" before it sinks. They should discover that the
flatter and
wider they
make it, the more clips it'll hold. Of course, they'll also
discover
they'll
need SIDES!! It's a neat activity.

ArdisEasy science experiments from A to Z:
A: AIR
SHOW:
Blow air through a straw onto your hand.
Ask: Can you feel the air?
Can you hear it?
Can you see it?
IDEAS:
You can feel moving air. You can hear air as it moves out of
the straw.
However, you cannot see air. Basically, air is a mixture of
two invisible
gases, oxygen and nitrogen. Since air is matter in the
gaseous state, it has
weight and can push against things. Air
also takes up space. Blow up a balloon and let the air out as
a demonstration
or fold a piece of paper to make a fan to show we can feel
moving air.B: BALL
SHOW:
Hold the ball high. Let go. What does the ball do? Why
doesn't the ball
drop up? Ask the class.
IDEAS:
As soon as the ball is released it begins to move down - that
is, it falls.
Every object is attracted by the earth's gravity. When an
object is free to
fall, the force of gravity pulls it "down." It pulls down
toward the center
of the earth.
C: CUP
SHOW:
Float a cup in a bowl of water. Put pennies into the cup.
What happens to
the cup? How many pennies did it take to make the cup heavy
enough to sink?
Let the class help you count the pennies.
IDEAS:
The cup on its own floats. As more and more pennies are put
into the cup, it
sinks deeper and deeper into the water.
D: DROP
SHOW:
Sprinkle some water with a medicine dropper or spoon on a
piece of waxed
paper. What happens to the water? Ask the children before you
tell.
IDEAS:
On waxed paper, water rolls up into drops of different sizes.
Water does not
seep into the waxed paper. As a result, each sprinkle of
water pulls itself
together to form a drop. Large drops are heavier and
therefore flatter than
small drops. When two drops touch,
they fuse (go together) into one larger drop.E: EGG
SHOW:
Stand a hard-boiled egg on its end. Let go. What happens to
the egg?
IDEAS:
When the egg is released, it rolls over and comes to a rest
on its side. If
the egg were perfectly balanced on one end, it might remain
upright. Since
the egg is not in perfect balance, gravity pulls it down to
the lowest
possible position, which is the position when the egg is on
its side.F: FLOAT
SHOW: Several objects that float; other objects that sink.
Why do some of
these float?
Why do some sink?
IDEAS:
Objects that are heavier will sink. Objects that are lighter
will float.F: FORK
SHOW:
Hang a fork from a string. Let the fork hit the edge of the
table. What do
you hear? Ask
the class as you show them.
IDEAS:
The fork gives off a sound when it hits the table, because
the force of the
impact makes
the tines of the fork vibrate, or move back and forth. The
vibrating tines
produce the sound. Forks of different sizes will make
different sounds. Your
child might want to show two different sizes of forks.G: GLOVE
SHOW:
Wear an old glove on your right hand. Hold an ice cube in
each hand. Which
hand feels
cold first? Show the class and ask, "Which hand do you think
felt cold
first?" WHY?
IDEAS:
The left hand feels cold first. The glove on the right hand
stops the flow of
heat from the
right hand to the ice. In other words, the glove is a heat
insulator. Hence
the right hand retains its heat and stays warm. The
unprotected left hand
loses its heat to the ice and feels cold.H: HOOP
SHOW:
Push a hoop. Ask the class, "what does the hoop do?"
IDEAS:
The hoop, like a wheel, rolls when it is pushed. The hoop has
the shape of a
circle. Of all geometric shapes, the circle is the one that
rolls on a
surface with the greatest ease. Of course, it is this
roundness that gives
the wheel its great importance in land
transportation. (You can also use small cars or trucks to
further demonstrate
wheel or hoop movement.)I: ICE
SHOW:
Put an ice cube in a dish. Let it stand for a while. What
happens to the
ice? Talk about it with the class.
IDEAS:
The ice in the dish melts into water. Ice is the solid (hard)
state that
water can assume at temperatures of 32 degrees or below. Ice
melts and
becomes liquid water again when the room temperature is more
than 32 degrees
F.J: JET
SHOW:
Make a jet flyer. Blow up a long balloon. Let go of it. What
does the
balloon do?
IDEAS:
Upon release, a jet of air pushes out of the balloon's
opening. As the air
escapes, the balloon darts around the room in a helter-
skelter manner. This
illustrates one of Newton's laws f motions, "For every
action, there is an
equal and opposite reaction."K: KEY
SHOW:
Try to pick up different kinds of keys with a magnet.
Which keys does the magnet lift? Why?
IDEAS:
If the magnet lifts the key, the key is made of, or contains
iron. If the
magnet does not lift the key, it does not contain iron In
that case the key
may be made of brass, aluminum or another non-magnetic
material.L: LIGHT
SHOW:
Hold your hand up in the sunlight. What do you see? Do this
outside.IDEAS:
You can see the shadow of the hand. It forms when light is
blocked by an
object through which light cannot pass. A shadow is an area
that is not
reached by the light.M: MAGNET
SHOW:
Line up some paper clips. How many paper clips can your
magnet pull?
IDEAS:
The number of paper clips that a magnet can pull gives a
measure of the
strength of the magnet. The stronger, the magnet, the longer
the train of
clips the magnet can haul.N: NAIL
SHOW:
Make a mark with nail polish at the base of your nail. Leave
the polish on
for a few days.
Where is the mark after a few days?
IDEAS:
After a few days the mark on the nail is above the base. As
the new nail
tissue grows, the old dead tissue is pushed out of the
finger. The movement
of the polish mark shows at what rate the nail grows.N: NUT
SHOW:
Display several nuts such as pecans, walnuts, almonds or
hickory. Ask: What
is inside the shell? Why are they important for the plant
they came from?
Crack the nuts.
IDEAS:
Nut is the popular name for a type of plant seed or fruit
which grows in a
shell of woody fiber. The term nut may mean the shell as well
as the mean
inside. The kernels of most edible nuts form highly
concentrated foods, rich
in protein.O: OIL
SHOW:
Put some water in a glass. Add some cooking oil. What happens
to the oil?
Ask the class if they can figure it out.
IDEAS:
The oil floats on top of the water because of two basic
characteristics.
First, Oil is less dense than water. Second, oil does not mix
with water. It
is possible to disperse oil in water for a short time by
shaking the mixture
vigorously. When the shaking stops,
however, the oil runs together and floats back to the top.P: PENCIL
SHOW:
Try to write on waxed paper with a pencil. What happens?
IDEAS:
The pencil does not write on waxed paper. In order to leave a
mark, the lead
(graphite) of the pencil must rub off on the paper. The waxed
paper is too
smooth. Hence, no graphite rubs off on it.P: POPCORN
SHOW:
A few kernels of unpopped corn. Show some corn that has been
popped. What
happened?
IDEAS:
Pressure of the heat makes it expand and change. We will pop
some corn to
help with this demonstration.P: PUDDING
SHOW:
Put a package of instant pudding in a quart bottle, plus 2
cups of milk, and
shake. What happens to the dry pudding mix, the liquid? Why?
IDEAS:
When the bottle was shook, the dry pudding and the liquid
start to mix. With
the pressure or energy, the ingredients start to change. When
allowed to rest
a few minutes we get semisolid PUDDING to taste.Q: QUARTER
SHOW:
Spin a quarter on a table. What do you hear?
IDEAS:
At first the quarter spins silently. When it begins to fall,
it rattles
against the table faster and faster. The pitch of the sound
rises. When the
quarter comes to rest flat on the table, the sound stops.R: ROCK
SHOW:
Look at a rock through a large magnifying glass. What do you
see?
IDEAS:
You see many different bits of mineral matter of various
colors and shapes.
Some are arranged in layers. Some are shiny, some dull; some
rough, some
smooth. Hunt for two or three different shapes or sizes of
rocks to use.S: STRAW
SHOW:
Place a straw in water. Hold your finger tightly on the top
end. Lift the
straw out of the water. What happens to the water in the
straw?
IDEAS:
The water stays in the straw. As long as the top of the straw
is kept closed
with the finger, the water cannot run out. As soon as you
take the finger off
the top of the straw, the water runs out. In the first case,
air cannot enter
the straw so the water cannot leave
it. In the second case, air enters through the top and the
water falls.T: TOP
SHOW:
Spin a top. When does the top fall and stop?
IDEAS:
The top falls and stops when the spinning stops. As long as
the top spins
rapidly, it remains upright. As the top slows, it begins to
fall. The
friction at the point increases. The top slows even more.
Then, the top
falls on its side and the spinning comes to a halt.U: UNIVERSE
TELL ABOUT:
Hold up a picture. Ask what you can see when you look up at
the sky on a
clear night.
IDEAS:
On a clear night, when there are no trees, buildings, or
mountains obstructing
the view, you can see half of the universe. You can see the
stars, planets,
the Milky Way Galaxy and nebulae. At times you can also see
meteors, comets
and the moon.V: VORTEX
SHOW:
We will put water in our sink to form a vortex with a few
children at a time.
Let the water run out of the sink. Ask, "What does the water
do as it runs
out?"
IDEAS:
As water goes down the drain, it spins around to form what is
called a vortex.
A similar vortex in a large body of water is called a
whirlpool. In air, a
vortex may result in a whirlwind, a hurricane, or a tornado.W: WATER
SHOW:
Pour some drops of red food coloring in a glass of water.
What happens to the
red color? Is it still bright red? What happens if you stir
it?
IDEAS:
The red color gradually spreads throughout the water. The red
is evenly
distributed; it is said to be in solution in the water.Y: YO-YO
SHOW:
Let a yo-yo go. What does the yo-yo do as it falls?
IDEAS:
AS the yo-yo falls, it spins around faster and faster. At the
bottom of the
string, the yo-yo is spinning fast enough to make it climb
back up the string
to the starting position.X: XYLOPHONE
SHOW:
Use a small xylophone. Hit a long bar. Hit a short bar. Which
bar makes the
higher sounds?
IDEAS:
The short bar gives off the higher sound. The shorter the
length of the
vibrating material, the higher the pitch of the sound. The
longer the length,
the lower the sound. Play a scale for the class. Let them
guess whether some
notes are high or low with our eyes
closed.Z: ZIPPER
SHOW:
Zip a zipper. Why does the zipper stay together when it is
closed?
IDEAS:
When the zipper is closed, it is held together by little
interlocking hooks on
each side of the zipper. (Show fingers interlocking also.)
These hooks are
pried apart by the slide when the zipper is opened.Crystal Gardens
6 tb Salt
6 tb Liquid bluing
6 tb Water
1 tb AmmoniaCombine salt, bluing, water and
ammonia. Pour over small
pieces of rock or
coal in a shallow GLASS or CHINA
bowl. Drip food coloring
on top if desire.
Crystals will begin to grow soon.
Add water occasionally
to keep crystals
growing. You'll probably want to
place dish on tray or
wooden board as
crystals grow over the sides of the
bowl.Nancy Leon Y-GRADALE'S GREENE

Giant Bubble Liquid1/2 c Joy or Dawn dish detergent
5 c Water; distilled is best
2 tb GlycerineMix the dish detergent with the
water. (Measure
carefully, it makes a big
difference. Stir. Add the glycerine
(you can usually get
this in a drug store),
this makes more durable bubbles. You
can bend a wire coat
hanger into a
circle and wind a string around it.
Depending on how big
you make your circle,
you get great big bubbles. The
string helps in getting
the liquid to stay on the
circle. You can also use straws and
string-Tie a 2 1/2
foot length of string
through 2 straws and unleash square
bubbles. The trick is
to dip your string
and straw thing into the solution,
then wave it through
the air. Break the bubble
off by flipping the apparatus up a
bit. Plain straws make
good bubble pipes.
Also try using the plastic
strawberry baskets, they make
lots of little bubbles.
It is fun to experiment with all
different bubble makers.
Big-time bubble making
is a bit like fishing. You'll have
much better luck in
cool wet weather. Early
evenings, nighttime and early
mornings are often good.
Just after a rain is
ideal. Don't throw any leftovers
away either. The longer
your solution sits, the
better it gets.
Silly Putty2 c White all-purpose glue
1 c Liquid starchWARNING: Non-Edible
Mix together well. Set on trays for
play, or use waxed
paper. Can be used as
the commercial Silly Putty is. Store
in an airtight

How about a little lesson on "air" being all around. You can
put a napkin in
a jar, turn the jar upside down and push it down under
water. The napkin
stays dry and students have to figure out that the air kept
the water out.A similar idea is to put a funnel in a bottle. Pour water
through the funnel.
Then do the same thing again, but make a seal around the top
of the bottle out
of playdough. The water will not flow.You could also use food color, oil and water and discuss why
they oil and
water don't separate.Another simple idea is to just do sink/float tests.
Good luck!
Dear Jeannine,
ABSORB and REPEL: I used a small tray with a paper towel on
it....
another small tray with wax paper taped on it. I set up 3
places
with this. I put red water on near one tray and yellow near
the
other tray.
The colored water was in baby food jars with an eyedropper in
each.
The child can try on the paper towel and watch it absorb.
Try in on
the wax paper and tip the tray and watch it glide. When the
child
wants to get rid of the drop on the wax paper, he/she can
just set a
small sponge on it and it absorbs it like magic. (After a
while the
wax paper needs replacing.)COLOR MIXING: Materials: 3 white ice cube trays....a small
pitcher
of water....3 sets of red, yellow, and blue colored water...
(NOT TOO
DARK)....9 eye droppers....3 trays or 3 towels.I'm giving you the way to set up for 3 people. If you only
have to
set one place for your class, then this is really easy. Each
setting: Tray or towel with white ice cube tray that has a
little
bit of plain water in each cube spot on it. The tray or
towel also
has 3 clear containers (Baby food jars?) with red, yellow,
and blue
water in them and an eye dropper is in each one.....The child
can
then dropper the colors in the cube tray and keep adding to
them to
make new colors. These are really beautiful pastels if the
colors
are light enough. Be sure to try it ahead of time. The
pitcher of
water is there for the child to put clear water in the tray
for the
next person. (OH....I forgot...You need a centrally located
large
container to be used as a dumping station.I I have 2 for you!
First one:
Get red cabbage leaves. Tear into little pieces. Put them
in a zip-lock
baggie (small, but not snack size) and add some very warm
(not boiling) water.
Close the baggie and gently squeeze the cabbage leaves. The
water will change
colors. Now the magic! You tell a story about a little bear
selling juice
outside his house. He loves blue juice, but no one else
seems to like it and
he isn't making any money. Along comes a fairy godmother.
She looks at the
little bear's juice and frowns. She then pours some of her
magic potion into
the blue juice (white vinegar) and WOW! The juice turns a
wonderful color.
Now everyone wants the little bear's juice!
You have changed the ph of the cabbage juice from an alkaline
to an acid base.
We did this in kindergarten when we talked about colors.
Each child did their
own experiment and were so proud of their success! Of course
the room smelled
a little like cooked cabbage...who cares!No. 2:
Pop rockets. Get several film canisters (a local pharmacy
has saved mine for
me). Decorate a piece of paper anyway you want and tape it
around the film
canister with it at the bottom (the paper serves no purpose,
just for looks).
Make a cone shape and attach it to the top (opposite end from
film canister)
Do not tape the paper to the film canister. You will need to
be able to slip
the cylinder off the canister. In the canister, fill it
about 1/3 to 1/2 full
of water-NO MORE! Practice flipping the lid off and on
quickly and slipping
the rocket cylinder over it QUICKLY. You are going to drop a
half an Alka-
Seltzer tablet into the water, snap on the lid, slip the
rocket cylinder on
and set it on the ground. In a few seconds, the rocket will
POP off the
ground.
We also did this one with 5 classes at a time. Ages ranged
from kindergarten
to 2nd. We had a countdown and everything! Great for the
last day of school!I have many more, but thought these two were impressive!
Have fun student teaching!Produced for parents, but lots of good ideas that can be used
in the
classroom for math and science experiences (or use 2-3 at a
time in your
classroom/school newsletters). Also, reference for writing
curriculum
philosophy:From U.S. DEPARTMENT OF EDUCATION
OFFICE OF EDUCATIONAL RESEARCH AND IMPROVEMENT
PROGRAMS FOR THE IMPROVEMENT OF PRACTICE:An easy and fun won is to get two funnels and attach a three
foot clear
tube between them _ I always used clay to seal, if they
didn't fit
perfectly. Let the kids experiment with gravity and have the
water go from
one to the other as they alternately raise them.
Another good one is the old kleenex in the water glass
experiment to show
how air keeps water off the kleenex. Put the kleenex deep in
the bottom of
the glass and then, of course, have them predict what will
happen . They
can take turns.
Another great one is the suction cup on the table. Get a car
dent puller
size suction cup and press it on a smooth table. Invite kids
to pull it
off. (Make sure they don't pull too hard or to pull off the
dge of the
table. Explain about the air pressure in the room.
I usually introduced three of these experiments in a small
group and let
the children take turns doing them.Have fun and expect some water on the floor!

Erupting Colors
*My own daughters loved this, and so do the kids I teach, all
ages !
Materials:
baking pan (I like to use a glass pan)
milk
food coloring
liquid dishwashing soapProcess
1. Pour milk into a cake pan to cover the bottom,
usually about 1"
deep.
2. Sprinkle several drops of food coloring on the milk.
3. Now add a few drops of dishwashing detergent in the
centers of
the largest drops of color. Watch the erupting, churing,
boiling
colors!
(If the colors stop erupting after awhile, begin again
from clean
milk and colors and detergent.)

Here are two science and art ideas on the theme of Crystals
from my book,
ScienceArts. These are fun to do in the winter or as the
weather turns frosty,
and when ice, and snow are more evident. And for some (Hello,
Denver! Hello,
Nebraska!), right now *IS* crystal time.
Crystal Sparkle Doughconcept words: crystals, dissolve, evaporate
Materials:3 squeeze bottles
3 cups
3 tempera paint colors
equal parts of flour, salt, water (about 1 cup each for a
standard art
experience)paper
bowl
spoon
Art Experiment:1. Use a spoon to mix equal parts of flour, salt, and water
in a bowl.2. Divide this mixture into 3 cups and color with tempera
paint to whatever
shade is desired.3. Fill each squeeze bottle with one of the colors of the
mixture.4. Squeeze the paint mixture onto paper in any design.
5. Let the paint dry thoroughly to see the crystals and
sparkles.
Notes:Works on wood, shells, cardboard.
Can be spread with a spatula instead of squeezed.
Varying the sizes of the holes in the squeeze bottles gives
different effects.

===============================================
There have been some new ideas thrown around about shadows
and light.
Here are a couple of ideas from my ScienceArts book which has
some
"magic" activities, that I love:
Shadow Painting
Need:
big paper
wide tip marking pen
stones to keep paper from blowing
paints and brushes
outdoors on sunny day (can work indoors too, of course, on a
sunny day or
with a bright light source)Do:
1. Find a shadow on the ground, such as from a tree.
2. Position the paper on the shadow to capture the shape.
Hold the
corners of the paper with stones, if needed. Or friends can
help hold it.
3. Outline the shape with the marking pen.
4. Paint in the shape of the shadow.
5. Remove the paper from the shadow and see what it looks
like !
(You can do this same thing by shining a bright light and
making
deliberate shadows of a chair, flowers in a vase, a friend's
silhouette,
etc. indoors. Trace. Paint. Or instead of painting, cut-out
and blue to
another paper.)LIGHT
Reflection Collage
Need:
aluminum foil
glue
black matte board or paper
sunshine, outdoor wallDo:
1. Glue pieces of aluminum foil on a piece of black paper in
any design.
Try to leave some blank spaces between the foil shapes.
Strips of foil
work especially well.
2. Dry a little until the foil holds well.
3. Go outside and hold the design up to a wall, capturing the
sunshine
and reflecting it on the wall. The design will be clearly
seen on the
wall.(Try this inside with a flashlight shining on the design.)
I've got lots more ideas if someone needs more...

"Bright Ideas for Learning"===============================================
GAK1-MIX: 2c. Elmer's Glue with 1 1/2 c. *HOT* water
2-DISSOLVE: 1T. Borax into 1 c. water & add to glue mixture
3-ADD: Food coloring
4-STORE GAK in an airtight container
===============================================
As an art project, make funny creatures by gluing googly
eyes, pom-poms,
paper scraps, etc. to small circular magnets. When they are
dry, tell
the children you will show them how to move their creatures
magically.
With a horseshoe magnet held behind a sheet of posterboard,
move the
creatures around. Let the children magically move their
creatures
around with the attracted magnets.===============================================

Pour small amount of bubble solution into bowl and add food
coloring.
Have child blow bubbles with a straw until the bubbles reach
the bowls
brim. Place a piece of paper on top of the bubbles in the
bowl. Lift
and see that the bubbles have transferred onto the paper. Try
alot of
different colors.===============================================
A silly putty like material can be made by putting about 1/2
inch of Elmer's
glue in a cup. Add 10 ml of water and stir.Mix about 1 tsp of Borax (20 Mule Team Borax in the grocery
section works
well and will provide you with about a 4000 year supply for
about $3.00) in
about 6 oz of water. Stir well. Add 5 ml of the Borax
solution to the glue
and water mixture. Stir. Remove the lumpy stuff and let sit
on a piece of
plastic wrap for a few minutes to get rid of teh stickiness.
To make larger
quantities, multiply the proportions accordingly.===============================================
Silly Putty
Sta Flo liquid starch and Elmer's School glue. Brand names
are important
here.
The recipe calls for about 5 glue to 3 starch. I never
measure it
though. Put the starch into a hard plastic cup (look at
dollar stores)
and then add the glue. Stir with your hands and fingers. It
feels like
brains. (So I am told by my first graders.) Warm hands work
better than
cold.

Unit: Physical Science-Matter primary
Matter and energy have observable characteristics
Lesson: What can matter feel like?
Adapted from Scholastic Science Place
Objectives: 1. The learner will be able to correctly
describe the textureof two
objects in the texture bag.
2. The learner will correctly describe
the texture of theirrubbings.
Materials: bags of things that have a variety of textures
(one for eachstudent or
for pairs of student), leaves, crayons, paper
Vocabulary Words- Matter= anything that takes up space and
has weightObserve= to notice things in the
environmentTexture= how something feels
Sorting/Classifying- to group
objects that are similarInstruction:
1. Motivation: Big Book- I Spy A Book of Picture
Riddles Use pages 12and
13 or 20 and 21. Ask children how the objects in the
pictures mightfeel and
how they know. Write the words on the board.
2. Introduce vocabulary words- place the words on the board
have thestudents
who are reading, read the words then I will give a
definition. Forclassifying activate prior knowledge by talking about
how we sortedbuttons
by colors and other characteristics.
3. Distribute bags of texture objects. Allow students to
explore theobjects.
4. One at a time have each child hold up two objects of
different texturesand
describe the texture of those objects.
5. Demonstrate how to do rubbings. Place paper over a coin
and rub crayonover the paper. Explain that rubbings can show the
texture of objects.Pass
out paper and have children do three to four rubbings of
objects fromthe
texture bags or around the room. Children should use
the side of thecrayon
to rub.
6. If possible create a bulletin board with sections for
different textures.Have the
children correctly place their rubbings in the texture
categories.
