MAKE A HELMET FOR AN
Do you know what a bicycle
helmet will do for you if you have a bike accident? It
will protect your head and your brain from serious
What would happen if you dropped an
egg that hadn't been cooked? It would break, right?
Pretend your head is that egg! Would you like to keep
your "egg head" from breaking? You can make a little
"helmet" to protect your egg!
Would you like to see how a helmet can
protect you? Try this experiment!
Ask your parents or a friend to
help you with this activity.
You will need these
a fresh egg
a plastic egg (if you have
one) to practice fitting a helmet on to
things to make a helmet
from, like paper, styrofoam, styrofoam packing
peanuts, bubble wrap, cardboard, plastic, string, and
What would happen if you dropped
a fresh egg from about as high as your shoulder? Would it
break? If it's OK with your parents, try it! It'll be
messy, so you might want to drop it onto a garbage bag.
(Be sure to wash your hands with soap after you clean up
the egg, because raw eggs carry samonella
What could you put around the
egg to keep it from breaking when you dropped
Think about how a bike helmet
protects a person's head. Look at your own bike helmet.
How does it protect you? How does it keep your head
Now, you can think about what to
put around your egg to keep it safe like a bike helmet
keeps your head safe.
You could use a plastic egg for
practice as you design your egg helmet. Plastic eggs
aren't as messy as real ones, and you can keep using your
plastic egg over and over again.
After you make a helmet that
protects your plastic egg, try it on a real
Put your helmet around the egg and
drop the helmet with the egg in it from shoulder
Does your helmet keep the egg
You might need to try design a
few helmets before your helmet protects your egg! Good
