Here's a fun activity that will introduce your fourth grader to the concept of frictionless motion by constructing a hovercraft.

This science fair project idea produces sounds by creating vibrations using different objects.

If your fourth grader is obsessed with all things glow-in-the-dark, then here's an activity that will really light up her imagination!

Help your fifth grader execute this experiment involving a lit candle (submerged in water!) to show him the wonders of heat energy transference.

On the next chilly, winter day, invite your fifth grader to make a hand warmer by experimenting with the loaded combination of a few natural ingredients.

Excite your fourth grader by recreating ancient Viking myths. This miniature longboat will explore the principle of water molecules expanding when heated.

Your third grader will delight in learning about sound waves as he observes the different sounds created by tapping on glasses with varying amounts of water.

If your science savy third grader is up for a challenge, let her bend light with a casserole dish!

Teach your child how butter is created by shaking up cream the old-fashioned way.

Help your curious third grader construct a dazzling spinning wheel that will teach him about the science behind colors while providing some silly entertainment!

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

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.

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.
