Let’s do an egg shell squeeze science experiment today!

Have you ever thought about how strong an egg shell is?  Most of the time we think of eggs as being fragile and breakable.  Let’s take a little deeper look at which is right…is an egg shell fragile or is it strong?

Can you squeeze an egg?

 

Egg Shell Science Experiment

About Egg Shells

The function of the eggshell is to protect the embryo from the environment, but it cannot be too strong otherwise the chick would not be able to break out and hatch. It is made of calcium carbonate, an important biomineral, which is different from hydroxyapatite, the mineral component of bone.

Phys.org

That means an egg shell needs to be really strong to protect the future hatching chick, but not too strong that the chick cannot get out of the shell.

One of the ways that this is possible is through the egg shell science that we are about to explore…

Knowing how easy an egg cracks, it makes sense to think they are fragile.  But they are extremely strong – so strong that you can squeeze an egg in these simple experiments and never break it’s shell.

We recommend doing this set of kitchen science food experiments in the backyard or over the kitchen sink!

Egg Experiment for Kids: Squeeze the Egg Shell!

Egg Shell Strength Squeeze Test #1

First, place an egg in the palm of your hand. Close your hand so that your fingers are completely wrapped around the egg. Squeeze the egg by applying even pressure all around the shell. I was nervous to try this and stood over my kitchen sink.  You can too. Did the shell break?

No.  Amazing, right?

Egg Shell Strength Squeeze Test #2

Try another way – Hold the egg between your thumb and forefinger and squeeze the top and bottom of the egg. Did it break when you squeezed it this way?

Egg Shell Strength Squeeze Test #3

Finally, hold the egg in the palm of your hand. Press only on one side of the shell. Do not squeeze the egg – just press on the side.

What happens?  Why do you think this happens?

Science Behind Egg Shell Strength

The Strong Shell: The egg’s unique shape gives it tremendous strength, despite its fragility. Think of an egg as a 3-dimensional arch. The egg is strongest at the top and the bottom. That’s why the egg doesn’t break when you add pressure to both ends like in our 2nd science experiment.

When you hold the egg in your hand and squeeze, you are distributing pressure all over the egg like in the first science experiment.  The curved shell can distribute this pressure rather than concentrating it all on one area. When an egg is cracked on the side of a bowl, it breaks as the pressure is concentrated on one side.

This also explains how a hen can sit on an egg and not break it, but a tiny little chick can break through the eggshell – the weight of the hen is evenly distributed over the egg, while the pecking of the chick is an uneven force directed at just one spot on the egg.
