Do
you think that you are pretty strong? Is your father or mother
strong? When you think of eggs, you probably don’t think that they
are really strong, do you? In fact, you probably think that they are
pretty weak, because if you drop them, they always break and make a
big mess.
This
science fair project is easy for students in kindergarten and first
grade to do. Usually, science fair projects want to prove that a
hypothesis is right (or wrong). For younger students, this can be
too difficult to do. Here is the question that you are going to
answer in this project: can you break an egg by squeezing? Can your
mother or father break an egg by squeezing it?
The
process of this science fair project is pretty easy. The equipment
is something that you have in every kitchen: eggs and a bowl. The
first step is to inspect the eggs to check and see if there are any
cracks in them. Eggs that are cracked should not be used. To see if
you can squeeze an egg, place it in the palm of your hand and close
your fingers around it. Then squeeze it as hard as you can (over the
bowl, of course, so you don’t make a mess all over the kitchen).
What happened? Were you able to squeeze the egg and break it?
Repeat
the experiment asking people who are stronger than you (and who have
bigger hands) to give it a try. Could they squeeze the egg and break
it?
If
you are doing the experiment right, you shouldn’t be able to
squeeze the egg and have it break. The reason why is that unlike
what we believe, eggs are really quite strong. When thinking about
how a chicken lays an egg, you can see that they are squeezed a lot,
but don’t break.
Taking
the same eggs that you tried to squeeze, break it (over the bowl).
How did you do it? You probably tapped it against something, making
a crack in the egg, and then were able to break the egg.
The
structure of the egg makes it very strong, and unless you break the
structure, even the strongest man in the world (or the person with
the biggest hands) can’t squeeze an egg enough to make it break.
So
was your answer to the question on whether or not you would be able
to squeeze an egg right? Since you have been playing with eggs, you
should make sure to wash your hands with soap and water to prevent
some of the bacteria and viruses that can be found in uncooked eggs.
After that, you may want to ask your mother or father to cook omelets
for dinner.
