Discover the strength of a dome

Some of the strongest shapes in nature are curves and domes. Think of the ancient temples, churches and buildings that are still standing after hundreds of years. Explore why a dome is so strong with your kids and help them learn about these cool scientific facts.

What you need:

Activity:

Tape some masking tape around the middle of one eggshell.

Cut the eggshell in half through the masking tape, leaving four eggshell halves.
