Over the last 3 weeks we have been investigating friction. We started by looking at how far toy cars moved on different surfaces. We looked for similarities and differences between the surfaces. We found that rough bumpy surfaces had more friction than smooth shiny ones. We used what we found to create our own surface to try and slow down a ball.
This week, we tested our surfaces to see which slowed the ball down quickest. We predicted which surface would be the best, created a results table and then found the average distance.
