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.

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.

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.

An hour glass, also known as a sand clock, keeps time. In this activity, your child will make her own sand clock and measure the time it keeps.

Explore the chemistry of latex polymers with this outrageous, hilarious science activity.

In this air pressure science experiment with a balloon and a jar, children will use heat to create a partial vacuum and suck a balloon into a jar.

Using an empty tennis ball can and a swimming pool, you will determine if it's possible to have a conversation under water.

Try this chemistry experiment with your curious kid and get some "shocking" results!

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?

Delight your budding scientist with this cool physics magic trick and teach her some basic physics concepts while you're at it!

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

Try this experiment to give your curious kid a more "solid" understanding of how temperature affects the states of matter.

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!

When you see those sunscreen "protection levels," what does that really mean? Try this experiment to find out.

Is it solid or liquid? Create oobleck and witness the amazingly weird oscillation between the two!
