Year 4 - Circuits and symbols

Date: 16th Jan 2023 @ 3:46pm

Today we had to draw circuits. We realised that it would be too difficult to draw the actual components (parts) of the circuit all the time and it would take too long. So we learned that components of a circuit have symbols. This made it much easier to draw a working circuit. We then explored using components such as light bulbs, wires, buzzers, batteries and cells to make different circuits. We found out that a battery (such as a car battery) has multiple cells, whereas a AA battery is actually a cell because it is singular. This made a lot of sense to us because a car battery needs more power and voltage to allow a car to work compared to a remote control which usually just needs one or two cells.
