| Grippy:
``Well, Cormo, it's time for your bath.''
|
Cormo is playing hop scotch and singing.
Aides roll large glass aquarium filled half-way with water onto stage front and center. |
| Cormo:
``I want to keep playing. Water's no fun!'' |
|
| Grippy:
``What would make water fun?'' |
|
| Cormo:
``If I were a whale, water would be fun.
Whales get to bubble and spout!'' |
Grippy picks up two yogurt containers and a
safety pin, and walks toward the aquarium.
Cormo, still hopping, hops near to watch. |
| Grippy:
``You can bubble and spout like a whale.
Come and try it. I'll poke a hole in this
yogurt cup and you put it under the water.'' |
Grippy pokes pin into bottom of yogurt cup
and gives cup, upside down to Cormo. |
| Cormo:
``I like those bubbles. But where's the
spout?'' |
Cormo is holding the yogurt cup under the
water. Bubbles come out the hole as she
speaks. Grippy hands Cormo the other cup. |
| Grippy:
``Here, push this cup into the first one
really fast, like you do when you're stacking
them to put them away.'' |
Cormo does as told. Water spouts up out of
the hole in the container. |
| Cormo:
``That's pretty neat. But now I need some
friends to show it to.'' |
|
| Grippy:
``Okay. I see some children out there.
Call some of them up here to play with you.
I'll poke holes in more yogurt cups for
them. |
Grippy pokes holes in yogurt cup bottoms,
using the pin. |
| Cormo:
``You, and you, and you. Come on and
play with me. What are your names?'' |
Grippy repeats each name as each child says
hers or his, and hands each a pair of cups. |
| Cormo:
``Like this....What do you think? What
else can we do?'' |
Children and Cormo make the cups spout
and bubble for a while. (I'm hoping some
child will think of using a cup as a funnel or
a scoop.) |
| Grippy:
``I see you all know how to pour water. Do
any of you know how to pour air?'' |
Cormo turns a cup upside down. |
| Cormo:
``I don't see anything pouring.'' |
Cormo turns empty cup upside down in the
air. |
| Grippy:
``Do you remember the bubbles you made
from the hole in the cup?'' |
Grippy mimes pushing the cup under the
water upside down. |
| Cormo:
``Yes. But when you pour, the stuff has to
come out from the mouth of the cup.'' |
Cormo holds a cup and points to the mouth. |
| Grippy:
``Okay. But what was in the cup that made
the bubbles come out the hole in the
bottom?'' |
This question is addressed to the children. (I
hope someone will say air.) This may take a
while. |
| Cormo:
``So, there's air in the cup when it's upside
down whether it's up here, or in the
aquarium under the water?'' |
Cormo makes appropriate gestures with the
cup. |
| Grippy:
``Can you think of an experiment to prove
that?'' |
Question is addressed to children. (I'm
hoping some child will turn a cup upside
down and push it under the water, and then
tilt the cup to let the air out. If not, Cormo
can do it and let the children copy.) |
| Grippy: ``You children are good at this.'' |
Cormo pats some of the children on the
shoulder. Grippy hugs others. |
| Grippy:
``The cup carries its own air supply, kind of
like an astronaut's space suit.'' |
Cormo holds up a picture of an astronaut in
a space suit. (I hope we can get a big one of
a space walk.) |
| Cormo:
``I've got an idea. If I stuffed a wad of
paper into the bottom of a glass, would it
stay dry when the glass is under water?'' |
Cormo wads up a piece of paper while
talking. Children respond to Cormo's
question. Grippy asks children why they
think the paper will or won't stay dry. |
| Grippy:
``There's only one way to find out. You've
got to do the experiment.'' |
Grippy will need to develop a gesture for
this phrase because it will be used often. |
| Cormo:
``Who would like to help me?'' |
Cormo picks a child to help. The child
pushes the cup with the paper in the bottom
under the water. Then the child pulls the
cup up. Cormo takes the paper out of the
cup. |
| Cormo:
``Who will check the paper to see if it's wet
or dry?'' |
Cormo picks a child. Child announces
verdict. (Paper will be dry if we did this
right -- if we didn't we should do this
experiment again and talk about how we
need to repeat experiments to be sure we get
the same results each time.) |
| Grippy:
``That's wonderful. There's enough air in
that cup to keep the paper dry. (if necessary
-- add `at least some of the time.') |
Cormo hands paper to Grippy to hold during
this speech. |
| Cormo:
``What else can we do with water that's
fun?'' |
Cormo will need to develop a gesture here --
she'll be asking similar questions often. |
| Grippy:
``Have you ever played with sinkers and
floaters?'' |
Question is addressed to children as well as
Cormo. If children answer, Grippy or
Cormo ask them to name something that
sinks and something that floats. (If we have
that thing on hand, we'll let the child put it
in the water to demonstrate e.g. rock, paper,
ball, wooden block, plastic block.) |
| Cormo:
``What about my buckets? Sometimes they
float and sometimes they sink.'' |
Cormo holds up set of buckets. |
| Grippy:
``First, show us how you make them sink.'' |
Cormo puts a bucket into the aquarium
sideways. It sinks. |
| Cormo:
``Like this.'' |
Cormo points at bucket. |
| Grippy:
`` Now, show us how you make one float.'' |
Cormo puts a bucket into the aquarium open
side up, like a boat. |
| Cormo:
``Like this. It's sort of like a boat. I can
put things in it, and it still floats.'' |
Cormo holds up plastic dollies and blocks,
and lets the children each take a toy. |
| Grippy:
``How many toys do you think your boat
will hold?'' |
|
| Cormo:
``Let's find out. I'll put this block in.'' |
Note the bucket will sink slightly when the
block is in the bucket. |
| Grippy:
``Come on (names of children), you can put
your toys in, too.'' |
Bucket continues to sink lower with each
addition. |
| Cormo:
``Did you see what's happening to the
bucket? It's sinking. Why would it do
that?'' |
Children try to answer this question. Hope
somebody will suggest seeing if the bucket
rises again if they take toys out. If not,
Grippy can suggest it. Bucket rises and
sinks as toys are removed and added. Make
this point! |
| Cormo:
``I think I know how to make it sink all the
way! I'll put a rock in it.'' |
Cormo picks up rock from apparatus table
and puts it into the bucket. Bucket sinks!
Some of the dolls may float to the surface. |
| Grippy:
``You did make it sink. But do you know
why it sank?'' |
Grippy needs another gesture here -- this is
another common type of Grippy question. |
| Cormo:
``Because it's heavy?'' |
|
| Grippy:
``That's a good question. Do heavy things
sink in water?'' |
|
| Cormo:
``Can we do an experiment?'' |
Again -- Cormo needs a gesture for this --
this is another frequent question. |
| Grippy:
``Sure. We can always do experiments.
Here are some heavy things. Here's a block
of ice and a piece of plastic.'' |
|
| Cormo:
``Plastic isn't heavy.'' |
|
| Grippy:
``It is if you have a big enough piece.'' |
|
| Cormo:
``Okay. Should I drop them in the water?'' |
Cormo picks up the ice and plastic. |
| Grippy:
``Is that your experiment?'' |
|
| Cormo:
``Yes. It will show if heavy things sink.'' |
Cormo drops ice and plastic into aquarium.
Ice floats. Plastic sinks. Cormo is
surprised. Some of the children might be,
too. |
| Grippy:
``What happened?'' |
Question is directed at children.
Grippy tries to get children to say that
there's more to sinking and floating than
being heavy. It depends on what material
you have. A tiny piece of plastic can sink.
A huge piece of ice can float. (we can have
these props available.) |
| Cormo:
``That's not what I expected. The heavy ice
floated and the light plastic sank.'' |
Cormo points at the ice and plastic as she
talks about them. |
| Grippy:
``I always love experiments that don't turn
out the way I expect. They help me learn
something new. And speaking of something
new -- here's Riddles. He's always got
something new to show us.'' |
Riddles comes on stage pushing a cart of
transparent glasses, a punch bowl, a ladle, a
siphon, a red cabbage, a grater, plastic
drinking straws, wadded paper, paper boats,
and empty strawberry baskets. |
| Cormo:
``Is he going to pull a rabbit out of a hat?'' |
Cormo pretends to pull a rabbit out of an
invisible hat. |
| Riddles:
``Any magician can do that. I'm a
scientific magician.'' |
|
| Cormo:
``What do they do?'' |
|
| Riddles:
``Scientific magicians do the unexpected.
But then they give away their secrets.
Science is for sharing.'' |
|
| Cormo:
``Show us something! Show us
Something!'' |
Cormo jumps around and gets the other
children excited, too. |
| Riddles:
``Have you ever seen water run up hill?'' |
Question is asked of all the children. If any
of them say "yes," ask if they know how to
make water do that right now. If they do,
let them demonstrate. Otherwise, get on
with the siphon. |
| Riddles:
``Water is going to run up inside this tube,
out of the aquarium and into this punch
bowl. And while I'm doing that, I need
some help for my next trick. Who will help
Grippy grate the red cabbage?'' |
While he talks, Riddles immerses the siphon
into the aquarium and when it is all under
water and bubbled, he puts his thumb over
one end.
Meanwhile, Grippy gets the cabbage and
grater and a small bowl and begins grating,
with the help of any willing children. |
| Riddles:
``Watch the water carefully. There's
nothing up my sleeve. You can do this at
home in the bath tub if you have a tube or an
old piece of hose. Pretty cool, huh?'' |
Riddles brings thumb-covered siphon end
over to the bowl and lowers it to the bottom.
Then he releases the water. He holds up the
tube so every one can see that the water is
flowing up hill. |
| Riddles:
``This is called a siphon. A siphon is a tube
that lets you move liquids from one
container to another without having to lift
them.'' |
By this time the water will be pretty high in
the bowl. Some children will be worried
that it will overflow. If they aren't Cormo
can ask if the bowl will overflow and make a
mess. |
| Riddles:
``Thanks for watching out for me. The nice
thing about siphons is that they connect two
containers, so the two containers act as one.
That means the water in the punch bowl will
never get higher than the water in the
aquarium. Cormo would you help me here?
Please lift the punch bowl up a few inches.'' |
Riddles uses his hands to indicate that the
water in the aquarium and the bowl are the
same height.
Cormo lifts the bowl and the water goes
down in the bowl as it goes back into the
aquarium. |
| Cormo:
``Would that work for a glass as well as a
bowl?'' |
Cormo puts down the bowl and picks up a
glass and gives it to Riddles. |
| Grippy:
``Isn't it wonderful that she's always asking
questions?'' |
|
| Riddles:
``I love questions! And I love to do
experiments to find out the answers. I'll just
scoop this glass into the bowl and over the
siphon. Then I'll take it out and see what
the water does.'' |
Riddles lowers the glass into the bowl and
inserts the siphon into the glass. Then he
quickly removes the glass and holds it so its
bottom is lower than the water level in the
aquarium. He moves the glass up and down
to see the water level lower and raise. |
| Cormo:
``It's working! It's working!'' |
Cormo jumps around. She encourages other
children to jump too. If any of the children
want to try the siphon with the glass, let
them do so. If they drop it, tell them that's
okay -- it takes practice. And the bathtub is
a good place to practice. |
| Riddles:
``And, if you don't have a tube or a hose,
you can move water with a drinking straw.
You just have to put the straw into the
water, cover the top with your finger, and
lift up. Like all magic tricks, it takes a little
practice -- but you'll get it. Then you can
carry the water wherever you want and just
lift your finger off the top of the straw when
you want the water to come out. Who wants
to try it?'' |
He demonstrates putting a drinking straw
into the water, capping it with a finger and
picking it up. Then he carries the water to
the bowl and lets it pour out.
As many children as want may try this. |
| Grippy:
``We've been playing with sinkers and
floaters. That's something else you can do
in the tub.'' |
Said while children are playing with straws. |
| Cormo:
``We saw something unexpected. We saw
the heavy ice float. And the light-weight
plastic sank.''
|
|
| Riddles:
``You saw plastic sink?'' |
Riddles picks up a plastic strawberry basket
while asking this question. |
| Cormo:
``Yes. It sank.'' |
Cormo gestures sinking to the bottom of the
tank -- she points to the sunken toys. |
| Riddles:
``Watch this.'' |
He puts the berry basket into the punch
bowl. It floats. |
| Cormo:
``How'd you do that?'' |
Points to floating basket. |
| Riddles:
``Magic.'' |
Waves hands mysteriously. |
| Cormo:
``You promised you tell all your secrets.
Remember!'' |
Points accusingly. |
| Riddles:
``Sometimes I don't tell. Sometimes I help
you figure my secrets out for yourself.'' |
Riddles includes all the children in this
statement. |
| Riddles:
``Here's a wad of paper. Watch what
happens when I drop it into the aquarium.'' |
Riddles drops the wad of paper into the
aquarium. It sinks. Children will tell him
so. |
| Riddles:
``Now, watch when I put this paper boat in
the water.'' |
Riddles puts the paper boat in the aquarium.
It floats. The children tell him so. Or if not,
Cormo tells him. |
| Riddles: ``Boats wouldn't be any good if
they sank. But boats are made of metal and
even cement, and other things that sink.
So, why do you suppose boats float?'' |
Riddles pushes the boat around on the water
as he talks. |
| Cormo:
``My bucket floated earlier -- until I put the
rock in it and made it sink.'' |
Cormo points out the sunken bucket in the
aquarium. |
| Riddles:
``Then your bucket acted like a boat. So,
here's a riddle: how is a bucket like a boat?
Or like a strawberry basket?'' |
Children should figure out that the shape is
what's important. Grippy can ask questions
to help with this process. Cormo can give
the answer if necessary. |
| Riddles:
``That's right. And I know something else
you can do with buckets. But since you
aren't magicians, you should do this
outside.'' |
Riddles retrieves bucket from the aquarium,
half full of water. He swings it over his
head several times. Then he pours out the
water back into the aquarium. |
| Cormo:
``That's pretty neat. But what's the red
cabbage for? You said that was your next
trick.'' |
Cormo brings the cabbage that Grippy has
grated to Riddles. |
| Riddles:
``You can dump the cabbage into the punch
bowl. It needs to soak for a while. And
while we wait, I'll do one more water
carrying trick and I'll show you.
Remember, ALWAYS do this trick over a
sink or a tub, and only use a plastic or paper
drinking cup. I'll place this 3x5 card over
the mouth of this cup (any piece of
cardboard or even stiff paper will do), and
I'll turn it upside down. You didn't know
you could carry water in a cup upside down,
did you?'' |
Riddles half fills a clear plastic glass with
water from the aquarium, covers the rim
with a 3x5 card and turns the glass upside
down. After he is sure the 3x5 card is wet,
he lets go of the card. The water stays in
the glass. |
| Cormo:
``Why didn't the water fall out?'' |
Points to water in cup. |
| Riddles:
``This paper is covering the opening on the
cup, just like your finger covered the
opening on the straw when you carried water
in that. Do you see anything in common
here?'' |
Riddles points to paper at mouth of cup.
Children can be led to saying something like
-- both are covering the opening you usually
drink from. |
| Riddles:
``That's right. And the cover keeps air
from getting in, as well as keeping the water
from getting out. Something has to be in the
cup -- either air or water.'' |
|
| Cormo:
``That makes sense. We poured air out of
the cup earlier. (child's name) would you
show Riddles how we poured air?'' |
child pours air and Riddles says something
happy. |
| Riddles:
``I know one more trick with air and water.
See this bottle of water. I'll poke this pin
into the bottle. Now you tell me what you
think will happen when I take the pin out.'' |
Riddles has 2 liter soda bottle nearly full
with water. He pokes a pin into the bottle
somewhere in the top third of the bottle, but
below the air line.
Children guess what will happen. Riddles
doesn't answer. |
| Grippy:
``Now, lets do the experiment.'' |
|
| Riddles:
``Here goes.'' |
Riddles pulls out the pin. Nothing happens. |
| Riddles:
``The pin hole was blocked by the water in
the bottle. Air couldn't get in through the
hole, so the water couldn't get out.
Something has to be in the bottle. Now if I
unscrew the top, and let air in, watch what
happens. Now if I screw it back down
again, watch what happens. Again.'' |
Riddles points at hole.
Riddles unscrews lid and water comes out
the hole. He screws it back on and the
water stops flowing. He repeats several
times. |
| Cormo:
``That's a good trick, Riddles. But what
about the red cabbage? Look, it's turned the
water purple!'' |
Cormo points to water in punch bowl. |
| Riddles:
``It's ready. Thanks for reminding me.
Now, where's my ladle?'' |
Grippy gives Riddles the ladle from the cart. |
| Grippy:
``I'm feeling left out here. What can I
do?'' |
|
| Riddles:
``Each of these glasses has a clear liquid in
it. I'm going to ladle some of the purple
cabbage water into each glass. Before I
pour, you can read the labels on these
glasses, so we'll all know what's in them.'' |
Riddles points to the labels on the glasses. It
would be nice to have slides flashing these
words on the stage at the same time. |
| Riddles:
``And I've got a job for each of you
children, too. (There should be 5 children,
or if only 4, Cormo can be one for this
trick.) I need each of you to name the color
you see when I pour the purple cabbage
water into the glass. I'll tap you on the
shoulder when it's your turn.'' |
Riddles pours cabbage water into lemon-lime
soda, vinegar, baking soda, clear
dishwashing liquid and ammonia. Grippy
reads each one. Child names color. |
| Cormo:
``That's a really good trick. Now tell us
how it works. Why does red cabbage turn
all those colors?'' |
Cormo points to all the colors of water. |
| Riddles:
``Some things even magicians don't know.
To learn that you'll have to study chemistry.
The trick you can remember is that sour
liquids like vinegar make red cabbage turn
pink. And slippery ones like soap make it
turn green. You can try out other liquids in
your kitchen.'' |
Riddles holds up appropriate glass as he
talks. |
| Grippy:
``And now Cormo, it's time for your
bath.'' |
Grippy stands beside aquarium. |
| Cormo:
``Not in front of all these people!'' |
|
