Explore Series Electric Circuits

In this worksheet, students will be asked to decide if a circuit is complete.

'Explore Series Electric Circuits ' worksheet

Key stage:  KS 2

Year:  Year 4 Science worksheets

Curriculum topic:   Electricity

Curriculum subtopic:   Switches

Difficulty level:  

Worksheet Overview

In this worksheet you must decide whether a circuit will work. For example, whether it will light a bulb or make a fan work.


Light bulb


As you know, electric current flows because it is pushed by cells (or batteries). For the current to flow right around a circuit, there must be no gaps in it.


Circuit with switch


If the circuit has a switch in it, and the switch is open, that's a gap: no electric current will flow.


Circuit with reed switch


The green component in this circuit is a type of switch called a reed switch. Reed switches are switched on by magnets - bringing a magnet near to it will close the switch and allow electric current to flow.


So, check whether a circuit is complete and whether the current can get round it.


Remember: the higher the electric current, the brighter any lamps will be, the faster a motor will turn and the louder a buzzer will sound.
