This science activity will help your student explore the changes that occur to transform an egg from raw to soft to hard-boiled.

The next time you've got a restless second grade earth scientist on your hands, use this experiment to demonstrate crystals and make a tasty treat, too!

In this physics project, learn about the relationship between light intensity and distance using a laser pointer, flashlight, and graph paper!

This science fair project focuses on a polymer called hydrogel super absorbent crystal which absorbs water, swelling to many times its original size.

What are buttress roots? In this fun science project, make a model of a rainforest tree and learn how they help trees survive in the tropical rainforest!

This science fair idea examines hydrogel superabsorbent polymer crystals. They can absorb 500 times their weight in water. Can they absorb other liquids too?

Did you even wonder why some rocks are round and smooth while others are broken up into small pieces?

The rock cycle will come alive for your child when he uses broken crayons to create the three basic rock types.

In this experiment, you'll make a seafloor spreading model to learn more about how plate tectonics work and create mid-ocean ridges.

In this experiment, your child will create two compost bins and see if he can determine what attracts fruit flies.

Kids learn how to prevent erosion by growing grass. They'll test soil with grass against raw soil in this revealing science fair project idea for 4th grade.

This science experiment examines the role of fat in food, especially in making bread rise and whipping cream.

Kids discover what a homogeneous mixture is by adding sugar to distilled water and identify the various factors affecting solubility.

Check out this cool science fair project idea to explore which other common animals besides scorpions glow under a UV Black light.

Saturn is the ringed planet in our solar system, a gas giant with rings made of ice and dust. Let's make a cool scale model with an old CD and some glitter!

Learn about the layers of the Earth and make a model! Create a earth layer book, cake, or clay diagram.

This science fair project idea determines if crystals will absorb food dye and if colors will mix by the process of diffusion.

How well can people recall what they have observed. Test your knowledge in this fun experiment.
