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

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

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

Show your child how to construct a homemade thermometer. It's hands-on fun and a great way to learn about this important instrument!

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