P4H Friction Experiment


Primary 4 have been exploring friction this week. We learnt that friction occurs between two surfaces that slide against each other.

We had a theory that the rougher the surface the stronger the friction. So, we carried out an experiment to investigate.

We had four surfaces to test out: smooth, woolen, corrugated card and foam.

We made predications on what surfaces would have the most friction then we went ahead with our experiment.

We had great fun testing out toy cars on the different surfaces!

We recorded our results and explained our findings. We discovered that smooth surfaces had less friction and the woollen surface had the most friction!
