Science fair project idea that examines different physical characteristics of a chosen animal. Make educated guesses about evolution based on animal's form.

In this science fair project, students discover how sedimentary layers form as sediments like mud, silt and sand settle over time.

This science fair project idea demonstrates that plants give off water.

Learn how different types of soil affect how animal tracks form in this experiment!

The objective of this science fair project is to examine the effects of temperature on salt and water solutions, as they form crystals over time.

In this science fair project, students learn how pressure can make the minerals in a rock line up in the same direction and form bands and foliation.

In this fun activity, kids practice measurement and boost fine motor skills as they learn all about how fossils form and even make a few of their own!

Dinosaurs were huge creatures that left behind huge footprints that lasted for millions of years. In this science fair project, kids learn how dinosaur tracks were left behind!

Use reusable, recyclable materials--along with a dose of imagination--to build a castle with first grade geometrical forms.

In this experiment, students will create their own version of coquina, a sedimentary rock thatâs formed by seashells and sand, cemented by seawater minerals.

How do we know that air exists when we can't see it, taste it, or touch it? Here's a classic experiment that will teach your kid some basics of aerodynamics!

Teach your child about recycling and gardening as she re-uses an empty plastic milk gallon jug to craft a swan-shaped plant container!

Make "fossils" with your child to hide in the sandbox or at the park or the beach, to help your child explore his archaeological side.

Take the art making outside: have your first grader make a clay relief sculpture of the natural world. This is a great activity for summer.

Do this experiment to help your first grader understand how salt can be removed from salt water. All it takes are a few household materials.

What's a crater, and how does it happen? Here's a kindergarten experiment with safe, nontoxic ingredients.

Help your kindergarten science maven explore the water cycle without getting everything wet.

Help your young learner discover why the insects that a spider eats stick to its web but the spider doesn't.

Does your child love learning about dinosaurs? Does he like digging around in search of hidden treasures? In this fun activity he'll do both!

It's a rare kid who doesn't like a sandbox. Next time you're out digging, build in some earth science, too.

Help your child add some flair to the family garden with pencil pinwheels!

This science fair project idea explores how length affects the weight a bridge can hold.

With some cookie dough and ordinary household objects, let your kindergartener explore how fossil imprints are made.

If you're looking for something to keep your kid busy on a warm day, and give him some writing practice in the process, bring on the mud!

What's cooler than an explosion? Not much! This simple science experiment lets kids build their own pop rocket. So put on your safety goggles and let her rip.
