This science fair project examines how tsunamis travel by simulating a tsunami moving around an island. You will generate a pretend tsunami in a swimming pool.

Every time a sound is produced it emits a sound wave. This experiment demonstrates how sound travels, using nothing more than a spoon and a string!

Using an empty tennis ball can and a swimming pool, you will determine if it's possible to have a conversation under water.

In this free science fair project, learn how to separate salt from water using heat. A great science project for elementary school kids.
