This trick uses vertical and horizontal forces to help your child to push apart your hands apart, no matter how hard you try to keep them together!

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

This project compares the strength of one, two, and three-ply toilet paper.

This science fair project idea explores if the length of the string that an object is suspended on has an effect on how fast or slow it swings.

In this cool engineering science fair project, kids learn how to build Hero's engine: an enlightening example of Newton's third law.

Young physicists will wrestle with a discrepant event: the Hammer Ruler Trick. They'll make some inferences about torque, balance, and center of gravity.

This science fair project idea explores how much force is needed to move a lever at different distances from the fulcrum.

For a fun family activity to introduce your child to genetics, have your child go on a search for dominant and recessive family genes!

This science fair project idea investigates if webbed feet help a duck (and others) swim.

This science fair project idea investigates if heat from direct sunlight is hotter than heat from reflected sunlight.

In this project, build an insect model that shows how the head, thorax, and abdomen fit together! Learn insect anatomy by constructing a paper mache critter.

Science fair project in which you will attempt to throw a ball the greatest horizontal distance possible by using different angles.

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.

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

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

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.

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

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.

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

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

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

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.

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

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

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.

In this hands-on design challenge your child will make their very own Rube Goldberg Machine.
