Level 2: Circuits

Electricity and magnetism · level 2 of 8 · rough age 7-8 (a guide for parents; anyone can start anywhere)

A circuit is a loop with no gaps. This level builds circuits with switches, tests which things let electricity through, and draws circuits with symbols the way engineers do. It ends with the circuits inside a Mars rover, from its power source to its wheels.

Lesson	You will be able to
A complete circuit	Say whether a circuit is complete and fix one that is not
Switches	Explain how a switch turns a bulb on and off
Conductors and insulators	Test which things let electricity through
Circuit symbols	Draw a circuit with symbols
More bulbs, more batteries	Predict how bright the bulbs will be
A rover's circuits	Follow the electricity from a rover's power source to its wheels
