This easy aerodynamics activity is a simple way to introduce kids to the scientific method.

4th graders construct an ocean food web to learn about consumers and trophic levels, food webs, and food chains in this cool ecology science fair project.

Why doesn't the ocean freeze? Students answer this question by simulating the chemical composition and temperature of arctic waters in their own home.

Science fair project which simulates the global conveyor belts on a small scale, and observes the effects of wind, density and temperature on water movement.

Turn the common pastime of constructing paper airplanes into a lesson on the physics of aerodynamics and flight with this fun science activity.

In this investigation, an oil spill is simulated in a jar to observe the damage that oil spills have on the ocean and ocean life.

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 project, you'll build a model of the earth, complete with all seven continents and four major oceans.

Find out whether a longer airplane will fly farther or a wider paper airplane.

You've heard all about oil spills, but can they really be that bad? After all, vegetable oil is in almost every yummy baking good from cookies to brownies.

This science fair project idea compares biodiversity between drops of water.

In this activity, your child will write stories about two different people. The stories will include similarities and differences in the ways each person lives in their communities.

Help your child celebrate the summer and the sun by making a sandy seascape.

No big beach party or a sudsy seafood feast should be without this bright, colorful tablecloth!

Take to the air with science by experimenting with helicopter seeds right in your own backyard!

This science fair project idea determines if the size of the parachute will change the rate at which an object falls.

This science fair project idea investigates how a bottom keel helps keep a boat from rocking back and forth.

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.

How does water pressure change with depth? Kids learn how pressure works underwater with this cool and easy demo.

Is it a bird? Is it Superman? No, it's your third grader's homemade miniature plane zooming across the room on a zip line.

Will increasing the amount of salt in water effect how slow or fast the water freezes?

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!

Let your future scribe's imagination run wild! Children have a hard time understanding fact versus fiction, and writing a tall tale can help.

What heats up fasterâwater or soil? 5th grade students test the specific heat of water against the specific heat of sand in this great science fair project.

How do animals keep warm? In this experiment, find out whether fat insulation resists cold temperatures and learn how this works in the animal kingdom.

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

Capture your beach memories—not with a photograph, but with a beach mosaic made from that classic beach souvenir, the shell.

Brine shrimp usually live in saltwater. Investigate how salt concentration (salinity) affects the rate at which brine shrimp eggs hatch.

Build a decorated box and fill it with research that can help you get to your dream location someday!

Is our water polluted? Help your young scientist understand the importance of taking care of the environment with this simple experiment.
