This science fair project idea explores whether white light can be separated into different colors.

Can you increase the light and plant growth in your garden using mirrors? In this experiment, measure light reflection and find out!

Learn about sound physics and do a survey experiment to explore the difference between sound and noise in this science project.

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!

Create clear sound shakers so your preschooler can observe and compare the different sounds that objects make!

This experiment will determine how different kinds of light affects the strength of bakerâs yeast.

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

Quickly update your child's room by decorating the switchplate over the light switch! It will add a funky flair to any room in the house.

Plants and light seem to be good buddies, but how far does the friendship really go?

Create your own light bulb and test filaments of different thicknesses to see which keeps the bulb burning for the longest time.

This science fair project idea discovers if an artificial light source will yield the same plant health and growth rates as light from the sun.

What causes sound? Here's a simple science experiment that adds a visual element to the science of sound to help kids better understand this tricky concept.

This science fair project idea investigates how images are influenced by changes in light.

Learn about where colors come from and how light absorption works in this fun experiment! All you need is a flashlight, construction paper, and cellophane!

This science fair project idea examines the actual cost of three household light bulbs by testing energy consumption.

Explore convex and concave objects and how they reflect light.

In this activity, you'll send your kindergartener on a scavenger hunt to find sounds and create a sound recording. Here's how!
