Earth and Space Science Fair Projects

Looking for science fair project ideas that will make your kid a star at his upcoming science fair? Education.com's editorial staff has curated a rich collection of cool Earth and space science fair projects written by our team of talented professional scientists, science teachers, and educational consultants. Our Earth science projects and Earth science experiments give inquisitive kids the opportunity to identify unknown minerals and discover why certain volcanic rocks can float. Our space science projects give students the chance to do everything from building a model rocket to determining the elliptical path of a planet's orbit using applied math.

Middle School
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.
Earth & Space Science
Fifth Grade
In this science fair project, learn how to model the hydrologic cycle, the continuous interchange of water between the oceans, land, plants, and clouds.
Earth & Space Science
Middle School
In this experiment, you'll make a seafloor spreading model to learn more about how plate tectonics work and create mid-ocean ridges.
Oceans
Geology
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.
Ecology
Elementary School
In this project, you'll build a model of the earth, complete with all seven continents and four major oceans.
