The hypothesis is that arches are strong because they exert horizontal as well as vertical forces to resist the pressure of heavy loads.

You will carefully break off the small end of four eggs, remove the egg white and yolk, and wind a piece of cellophane tape around the center of each eggshell. Then, you will cut through the center of the tape to make four dome-shaped shells and lay them on a table with the cut sides down arranged in the shape of a rectangle. Finally, you will guess how many telephone books you can lay on top of the shells before they break.

You will need four eggs, tape, and books.

This experiment demonstrates how arches are used in architecture not only for aesthetic appeal but for a very useful and needed purpose. The crown of an eggshell can support heavy books because the weight is distributed evenly along the structure of the egg.

This science project is interesting and unique because it uses everyday materials to demonstrate a complex concept.

Experiment variations to consider include using different materials to make the arches, such as cardboard or paper, or using different objects to test the strength of the arches, such as coins or marbles.
