Science fair project that helps you create your own compost pile in order to test the efficiency of different methods of composting.

Learners hypothesize about and experiment with soil erosion in this hands-on activity.

Test your skills as a weather forecaster, and learn some science terms on the way!

Kids will love making clouds and learning how to make a water cycle model in this fun science fair project idea that explores evaporation and precipitation.

Can you think of a way of cleaning dirty water using the sun? In this activity, you will be making a "solar still" that is able to do just that!

Try this activity with your child to explore what happens to rain (and the living things that need it) when it becomes polluted.

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