A couple of weeks ago, Ann Marie’s 4th class were learning all about Electrical circuits; have a look at all we learned…………..

Electricity can flow through the components in a complete electric circuit. We can use symbols to draw circuits.

Circuits

A circuit always needs a power source, such as a battery, with wires connected to both the positive (+) and negative (–) ends.

A circuit can also contain other electrical components, such as bulbs, buzzers or motors, which allow electricity to pass through.

Electricity will only travel around a circuit that is complete. That means it has no gaps.

Switches

• When a switch is open (off), there is a gap in the circuit. Electricity cannot travel around the circuit.
• When a switch is closed (on), it makes the circuit complete. Electricity can travel around the circuit.

Have a look at the photos of the class doing various experiments and even making our own switches!!
