What You Do
What Is Happening
- Pick up one egg.
- Hold your hand over a sink just in case the egg breaks!
- Place the egg in the center and palm of your hand.
- Close your fingers around the egg. Squeeze the egg as hard as you can.
When we break an egg, we usually tap it against a hard surface to crack
the egg's shell. When you were squeezing the egg, the force and pressure
of your squeeze was being spread out over the whole surface of the
eggshell. The egg is designed so it won't
easily break in the outdoors and the wild. The egg's shape and its shell
are made so it will protect the baby growing inside until it is ready to
hatch and come out into the world. The egg is kind of like an arch with
three dimensions. It is one of nature's strongest architectural designs!
