This homemade barometer allows your little scientist to contemplate and compare different air and weather conditions.

Did you ever think you could make colors disappear right before your eyes? This science experiment is just like a magic trick: now you see it, now you don't!

In this sound experiment children listen for differences as they tap on a bag of air, a bag of water, and a wooden block held up to their ears.

Explore the scientific concept of capacity by seeing how many pennies you boat can hold before it sinks!

Explore solids and liquids with your young scientist by making gluep, a goopy substance that can behave like both a solid and a liquid!

Create a homemade pair of sunglasses with colored lenses to see just how light and color affect our sight! Use this fun project to practice science!

Believe it or not, images that are cast upon your eye's light-sensitive screen (called the retina) are upside down. Here's a fun, fast experiment to prove it!

Here's an interesting activity that will enable your child to make his own magnifier out of a drop of water

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 science fair project, young children discover what happens when two fluids that have different densities get together.

This classic children's game-connecting two cups with a string-demonstrates sound's ability to travel through air vs through a solid.

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.
