In Year 3 we have been very busy looking at forces. We wanted to test whether different materials affected how far cars would travel.
We used 7 different materials; tinfoil, bubble wrap, wood, foam, corrugated card, sand paper and felt. We talked about how to ensure it was a fair test we would use the same height of ramp, the same car and the same person doing each job. Before we carried out the investigation we made a prediction about which material we thought the car would travel furthest on.
We had 6 groups and each group tested the ramp once. We combined these results to find out the overall result.
We had great fun and used lots of scientific language.
