Simple Circuits
- Introduces students to the Locktronics board and components.
- Shows students that you need to have a complete circuit (path for electricity to flow) for a circuit to work.
- Students build circuits with bulbs and switches and explore altering their order.
Using Switches
- Explains that closed switches allow current to pass through and open switches stop it from flowing.
- Students then experiment with a simple bulb and switch circuit to think about current routes.
Buzzers and Motors
- Shows that some components change their behaviour if you change the amount of electricity that flows through them.
- Students investigate how the pitch of the buzzer changes with voltage.
- Students investigate how the speed and direction of the motor can also be changed.
Energy Changes
- Shows that electrical circuits always involve energy changes (transfers).
- Students can draw simple energy transfer diagrams.
- Students build a circuit and look at the energy changes which each component makes.
