Kids are sure to be entranced by the magic of the ocean when they create their very own ocean in a bottle.

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.

This science fair project idea demonstrates sonar mapping of the ocean floor.

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.

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

This science fair project examines whether ocean water can be made safe to drink.

Can't make it to the beach? Bring the science of ocean waves home with this fun earth science-related craft.

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

Help your preschooler practice observing and experimenting with this exciting activity where they'll get to examine objects below the water's surface!

This fun activity makes use of pasta shells, paint, and glue make a crab while your child learns about this unique creature.

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.

In this experiment you explore how tectonic plates move to create land and expand bodies of water.

Ignite your kindergartener's love of adventure and learning with an imaginary trip under the sea.

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.

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.

Science fair project that explores the natural process of limestone formation.

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

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

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.

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

Invite your kindergarten marine biologist to practice in scientific identification and categorization while creating a lovely treasure box.

Check out this silly game that will put your kid's animal habitat knowledge (and acting skills) to the test.

The objective of this project is to evaluate whether a top will spin at different rates during different phases of the moon.

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

Study the effects of wind and temperature on evaporation. Place wet sponges in different environments, check at regular intervals, track time required to dry.

What if the shape of the Earth weren't spherical? How does its shape affect our gravity, climate, and tides? Model these questions in this cool project!

This science fair project idea uses the process of chemical weathering to change a mineral.

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