Our new mini- topic named ‘Power’ has begun this week. During this topic we will be learning mainly about forces and magnetism. So we began by looking at friction.
We choose different surfaces to test out: hessian, plastic, sandpaper. Then, we rolled a small car down a slope across the surfaces and measured how far the car rolled.
We then graphed our results to find out which surface produced the most friction. It was really important that we measured accurately and kept all the other variables such as the length of the slope the same.
Stay tuned for more investigations!
