Why Are Eggs Egg Shaped Animal Science Experiment
Have you ever wondered why eggs are shaped the way that they are shaped? This animal science experiment will investigate the interesting shape of eggs. Before beginning this experiment, hold an egg between your thumb and pointer finger with the pointy end of the egg pointed upwards. Gently and steadily squeeze the egg. Did the egg break and if so was it easy to crush the egg?
Materials:
- Four eggs (extras needed if the shells get smashed)
- Scissors
- Several books of approximately the same weight.
- Masking tape
Instructions:
- Crack the eggs into a bowl and save to use in a separate meal later. You are trying to roughly crack the eggs in half.
- You may accidentally break a few eggs during the step so have a few spares available.
- Rinse and dry the shells.
- Now place a piece of masking tape around the open end of each shell to use as a guide for trimming.
- Use the scissors to trim each shell. You want the trimmed shells to all roughly be about the same size.
- Once you have four shells prepared, place them in a rectangle shape on a hard flat surface.
- Begin stacking books on top of your eggs until they eventually collapse.

How it Works:
They shape of the egg provides strength and keeps the eggs from easily cracking. If eggs had corners they would be more susceptible to cracks and not as strong. The oblong shape of the egg also keeps it from easily rolling out of the nest.
Make This A Science Project:
Arrange the eggshells in different patterns before stacking the books. Does this effect the amount of weight the eggshells can support?
