A TOUCHY SUBJECT
Where's
your sense of touch? It's
in your skin -- and your skin covers your whole body.
The bottom layer of your skin can sense pressure, pain, heat and
cold. Nerves in your skin
send information to your brain. It's
your brain's job to figure out what your skin is touching!
INSTRUCTIONS
Put
your finger in the first hole. What
do you feel? When you think
you know what's inside, find a game piece with a picture that matches
your guess. For instance,
if you think you feel fur, find a game piece with a picture of fur on
it. Put the right game
piece in the first hole. Now, check out the next hole.
When every game piece is in a hole, check the back of this flip
book for the right answers!

HOW DO I TASTE?
Human tongues can only taste four flavors:
bitter, salty, sour and sweet. We
taste each flavor on a different part of our tongues.
So how do we know whether we're eating chocolate cake or peach
cobbler? The taste buds in
our mouths send information to our brains.
Our brains process the information and tell us what we're
tasting!
INSTRUCTIONS:
Try
putting together the puzzle. When
you get it right, you'll have a map of your own tongue! Check the last page of this booklet for the right answer.
When
you get home, try this! Get
four cotton swabs. Dip one
in salty water, one in sugar water, one in vinegar and one in
horseradish. Touch the different foods to different parts of your tongue.
How accurate is the tongue map?
COOL
STUFF ABOUT YOUR TONGUE
Human
beings have almost 10,000 taste buds, some on the roof of their mouths.
Girls
usually have more taste buds than boys.
Insects
are better at tasting than any other animal.
The
older you get, the fewer taste buds you have.
NOW HEAR THIS
Clap
your hands. When you do,
vibrations called sound waves start moving through the air in all
directions. Some sound
waves hit your ear drum and start it vibrating.
The vibrations send a message through your inner ear and on up to
your brain. Your brain
tells you "I hear clapping!"

up the bottle labeled #1 and shake it.
What do you hear?

together, find a picture of paper clips.
- Put
the picture in the slot above the bottle, and put the bottle back.

the same thing for all the bottles.
- When
you're done, check the next page for the right answers!

SUPER
SNIFFER!
Your
brain can recognize almost 10,000 different smells.
But how do smells get to your brain?
Smells start as tiny particles – little bitty bits of rose, or
peppermint, or tar or smoke. The
smell particles make their way through the mucus in your nose to the
olfactory (smelling) bulb. There,
they fit into a special nerve cell that's ready to receive the
particles. The nerve cells
send a message to your brain to let you know it's time to smell the
roses.
INSTRUCTIONS
- Pick
up the bottle labeled #1 and sniff it.
What do you smell?
- Find
the picture of the smell. For
instance, if you smelled chocolate, find a picture of a chocolate
bar.
- Put
the picture in the slot above the bottle, and put the bottle back.
- Do
the same thing for all the bottles.
