Use chemical analysis to identify a variety of mystery powders that look the same but actually have very different properties.

What's the best way to make DIY compost? Kids will learn about aerobic and anaerobic decomposition while learning to appreciate the value of composting.

In this challenge, students are tasked with creating a car that can be powered by a balloon!

In this science and engineering activity, children will explore types of tunnels and their purposes and then design and build a tunnel of their own.

Use a dichotomous key to identify plants or animals.

How does a compass work? What's a magnetic field? Kids will build their own compass at home to find the answers in this great science fair project idea.
