Earth Science Fair Projects

Our earth science fair projects page features anything that can be considered an earth science. These include geology science fair projects, meteorology science fair projects, oceanograhpy, and more.

Each science experiment will show you what you need and simple instructions for how to perform the experiment. All are free science experiments for kids and discuss the scientific principles demonstrated by the child science project.

I recommend these printable science project plans for K-12 for hundreds of great project blueprints and this step-by-step guide for doing an award winning science fair project. Also be sure to check out these fun science kits as a fast, simple way to get started on your science experiment.
