More batteries, brighter bulb
Associate the brightness of a lamp or volume of a buzzer with the number and voltage of cells used in a series circuit
Suggested ages 10–11
Learning journey
Your child is learning how electricity works in circuits — understanding how batteries power different components like bulbs and buzzers, and how to draw circuit diagrams using proper symbols.
Evidence of understanding
- Describe the pattern: more cells (or higher voltage) = brighter bulb / louder buzzer
- Explain that more cells provide more energy to the circuit
- Predict the effect of changing the number of cells on a component's behaviour
Assessment prompt
Can More batteries, brighter bulb explain why adding a second battery makes the bulb brighter, and predict what happens with three batteries?
