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

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

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.

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.

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