Year 6 pupils have been putting their science skills to the test by exploring voltage and discovering how it affects the brightness of a bulb. During the lesson, children worked collaboratively to build electrical circuits using cells, wires and bulbs before making predictions and carrying out investigations.
The budding scientists calculated the voltage in different circuits by counting the number of cells used, learning that each cell provides approximately 1.5 volts. They then observed what happened when additional cells were added to the circuit. Pupils quickly discovered that increasing the voltage made the bulb shine more brightly, while fewer cells resulted in a dimmer light.
Using careful observations and scientific reasoning, the class recorded their results and identified a clear pattern between voltage and brightness. Through practical investigation, pupils developed their understanding of how electrical energy is transferred around a circuit and how voltage affects the output of electrical components.
