This project tests the hypothesis that dark colors absorb more heat than light colors.

In this CD hovercraft science project, students will construct their own DIY hovercraft.

This classic children's game demonstrates how sound travels through air vs. through a solid.

How does a kazoo, the strings of a guitar, or the speaker of a radio make sound? The purpose of this science fair project is to show how vibration makes sound.

In this Bernoulli's Principle experiment, you'll learn how an increase in the speed of a fluid, like air, decreases pressure.

Demonstrate how you can make your own compass using a magnetized needle. It also allows you to compare magnetic north and geographic north.

Stir up some friendly competition with this tabletop bow and arrow craft!

In this science fair project, students focus sunlight with a magnifying glass and trap shorter waves to melt ice.

In this experiment, students find out what happens when a less-dense fluid interacts with a denser one, replicating the effect of cooler solid rock on magma.

Here's a great activity that uses corks and toothpicks to create a fleet of floating boats. Which design makes for the most seaworthy vessel?

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

In this activity, your child will learn about a style of gardening that uses moss, also called "kokedama."

Air invisible; it doesn't make sounds; you can't pick it up and throw it. So how do we know it exists? Help your second grade scientist figure it out.

Teach your little scientist about the amazing powers of gravity by comparing the falling speeds of two yummy fruits

In this science project, the center of gravity is explored.

In this project, waves of vibrations are experimented with using water in glasses.

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

The objective of this science fair project is to experiment with balancing everyday objects and observing the the effects of gravity on materials.

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

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

What is a compound microscope? Kids find out by making one of their own in this cool science fair project.

This quick and simple preschool mirror activity will introduce your child to the science of reflection and light with a flashlight experiment and picture game.

This science fair project idea investigates whether air has mass and weight.

The project investigates how friction affects motion by using different surface textures.

This simple heat transfer experiment is a great introduction to the concepts of heat transfer and conduction.

Develop your kindergartener's fine motor skills while tracing shadows on a sunny day with this fun kindergarten activity.

This project explores ways to prevent static electrical shocks.

This science fair project idea investigates how the height at which a pendulum is released affects the length of time it continues.

This science fair project idea examines liquids of different densities.

This science fair project idea discovers whether there are some objects that do not fall at a constant rate.
