In our science lessons, year 2 and 3 have learnt about lots of different forces. Last week we learnt about how friction is a force and that it is the action of one surface rubbing against another.
We planned an experiment to see which surface caused the most friction when a toy car rolled on it. We made predictions, worked out how to keep our test fair and then set up the school hall with benches and different surfaces and got ready to roll!
The children worked in groups to time how long it took a toy car to get down a ramp, with different surfaces on it. The class discovered that the fake grass caused the car to move slowest, therefore it was the surface that caused the most friction!
Here are some photos of our experiment in action:
