We predicted that the more lamps we added to our electrical circuit, the dimmer the bulbs would be. To prove this scientifically we worked in groups to use a data logger to measure the brightness of the bulb when there was 1, 2 or 3 lamps in our circuits. We had to ensure that we kept our test fair and we also repeated our results to ensure they were accurate.
We begun our new Electricity topic by recapping on what we had learned before. We built complete circuits and began to investigate what happened when we changed different components in our circuits.
