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.

This project demonstrates the correspondence between the volume of water displaced by a submerged object and the volume of the object displacing it.

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

Invite your fifth grader to test the different rates of liquid absorption in synthetic and cotton materials, such as nylon and cotton.

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!

What happens when colored beams of light mix? You might be surprised.

Help your fifth grader execute this experiment involving a lit candle (submerged in water!) to show him the wonders of heat energy transference.

This experiment that explores water and air pressure will amaze your fifth grader as it appears that a single card is holding water in an upside-down glass.

This science fair project demonstrates the principles of reflection through simple experiments involving mirrors and light.

Get your fifth grader involved in some earth science by helping her plan and create her very own rock collection.

Experiment with buoyancy to learn how a submarine rises and sinks in this classic science experiment.

Based on the concept of water's "freezing point," this activity entails the lowering of water's freezing point to chill ice cream!

This science fair project creates a visual model of whatâs happening to sound waves as a car approaches and then leaves.

Learn with makes water molecules work with this fun and easy science activity!

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