Get your hands on a concoction that breaks the rules about what's a solid and what's a liquid.

Help your child get a grasp on what it was like to build gigantic ancient structures with this easy engineering activity about science and physics.

What's a liquid? What's a solid? What better way to experiment than by turning a childhood favorite, ice cream, into a homemade science lesson!

This taste buds science experiment demonstrates how strongly our sense of smell controls what we taste.

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 idea is to determine if sound travels best through the air, water or a solid.

What is it about a Slinky that causes it to walk down the steps? This simple experiment is a perfect illustration of both gravity and momentum.

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!

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

The purpose of this science fair project is to build a basic radio.

Hone your child's skills of observation and take a look at forensic science for an interesting afternoon of exploration and detective work!
