Year 3 children had a great time playing with toy cars and letting them run down ramps covered in various materials this week as part of their investigation into friction.The objective was to discover which material – either carpet, wood, foam rubber or sand paper created the most friction. We rolled a toy car down each ramp, starting from the same height to make it a fair test. We learnt how friction was a force that slowed things down and occurs when two surface rub together. Eventually, the children concluded that the roughest material i.e. carpet created the most friction and wood, which was the smoothest surface, created the least friction.
