In this science fair project, students make their own rain gauge to measure rainfall.

In this science fair project, students discover how sedimentary layers form as sediments like mud, silt and sand settle over time.

In this free science fair project, learn how to separate salt from water using heat. A great science project for elementary school kids.

In this fun science fair project, make two different scale models of our solar system using Astronomical Units and planets' relative size!

Science fair project examining barometric pressure, and how it can be used to predict the weather. How does atmospheric pressures relate to weather conditions?

Does your child always demand to know why the sky is blue, how the sun moves across the sky, or where wind comes from?
