Testing Compression Strength: Standing on Eggs

Good afternoon scientists! My Little scientist stood on eggs today! Try it with your little one, but be ready to clean up just in case the egg carton tips over.Standing on Eggs

Materials

2 Dozen Large Eggs in Cartons  (We didn’t have two full cartons, but we had just enough to fit our little scientists feet.

Investigation

**Eggs can have diseases on them, be sure to wash you hands, feet, and floor thoroughly when done**

  1. Set out your egg cartons next to one another (go outside if worried about a mess). Have your little one step onto and stand on the eggs! It is super cool. Feeling especially talented? Try setting up several egg cartons and walk one the eggs.
  2. Be sure to wash your hands, feet, and surfaces when done.

Talking Points

Eggs are super fragile, but when placed vertically, like in their cartons they actually are quite strong.

Egg shells are made up of Calcium Carbonate. Calcium Carbonate is basically the same material used to make ceramics.

Compression Strength is a materials ability to reduce compression (basically getting pressed together).  Eggs have a very high compression strength, chicken eggs have a compression strength of up to 100 pounds. 

Eggs are also arch shaped which helps them to distribute the compression force of standing on them and spread out the weight evenly among the eggs.
