This activity will help your child review science concepts, learn new ones, and become familiar with examples of various concepts in science. Plus, it's fun!

Find a mathematical relationship between the intensity of a sound wave and distance from the sound source. Use a pedometer and a sound level meter.

Is it solid or liquid? Create oobleck and witness the amazingly weird oscillation between the two!

Teach your child some scientific basics as you explore the densities of various liquids in this fun experiment.

In this fun science fair project idea learn about the multiple sources of radio waves and fin out how difficult it is to block them.

In this physics project, learn about the relationship between light intensity and distance using a laser pointer, flashlight, and graph paper!

In this cool science fair project, kids apply basic algebra to learn how to make a PVC pipe instrument while exploring concepts like frequency and resonance.

In this cool sound resonance experiment, learn about frequency and pitch, and use a tuning fork to calculate sound velocity in air.

Look for a correlation between temperature and the intensity of cricket chirping. Measure ambient temperature and sound intensity in decibels.

The goal of this science fair project is to evaluate the effect of heat on sound wave frequency.
