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!

Children combine an acid and an alkaline substance to simulate a volcano eruption in this fun experiment.

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

This science fair project demonstrates the principles of reflection through simple experiments involving mirrors and light.

This experiment that explores water and air pressure will amaze your fifth grader as it appears that a single card is holding water in an upside-down glass.

Science isn't ho hum anymore when it involves building catapults to teach your fifth grader about projectile motion.

Take advantage of the fact that ink and water don't mix and introduce your kid to suminagashi, a Japanese form of art.

Observe how your brain works while it is focused on one thing, and how it works while you are distracted by another thing.

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.

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

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.

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 Mother's Day, mix in some fifth grade science learning to create this fabulous fudge!

These flying potato poppers make a cool sound, create a celebratory mood, and they can teach your child about the power of air pressure.

Wondering how we know that air is there? Here's a quick and easy experiment that proves that air may be thin, but it's not too wimpy to block your shot!

This surprisingly good glue recipe comes from common kitchen items.

Try the classic balloon-on-the-wall trick with your kid and watch static electricity in action.

Introduce your child to the world of motion and physics with a bit of marble play inspired by Sir Isaac Newton!
