Introduction to Circuits
Light up the class's knowledge. Pupils build a simple circuit using a battery, wire, and a light bulb and create a diagram of their circuit. The teacher provides a short lecture on a complete circuit, calling attention to the direction...

Splitting Water with Electricity
Explore how electricity splits water molecules into hydrogen and oxygen. Learners begin by calculating the voltage necessary to separate the water. They then perform the experiment and measure the ratio of hydrogen and oxygen bubbles.

What Is Rust?
Why do metals rust differently? Scholars experiment with metal combinations in a hands-on activity. They create unique environments with different metals and compare the rate and amount of rust for each.
