Check out this mind-blowing experiment in which a hard-boiled egg will fit through an impossibly small opening with the help of only a few matches!

All you need are pencils, paper and some scissors to get started on this easy and fun game to review astronomy information, or other types of study concepts.

This experiment uses a yeast solution, liquid detergent, and hydrogen peroxide to produce an exciting reaction like no other!

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!

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

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.

This science fair project examines how tsunamis travel by simulating a tsunami moving around an island. You will generate a pretend tsunami in a swimming pool.

Learn how to make marbleized paper with simple everyday ingredients in this fun activity! Your child will learn about oil and water while doing this project.

Would your child like to learn about a hidden world? All she needs to do is open her box of markers!

Based on the concept of water's "freezing point," this activity entails the lowering of water's freezing point to chill ice cream!

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.

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

Here's a fun at-home activity that will help your child strengthen math skills using high and low temperature data, and become a master temperature tracker!

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!

Little scientists will make inferences about hearing loss, pitch, and frequency in this great science fair idea that puts the human ear to the test.

How to test for acids and bases? In this activity you and your child can make your own indicator from red cabbage!
