The Friction Test

We have been looking at the effects of friction on speed. We spoke about how friction can be a good thing and a bad thing. 

With our model cars we tested different road surfaces to see how far they went with more and less friction. We tested using the lino flooring in the classroom, with a carpet, with the underside of a carpet and with laminate flooring boards. Each time, we used the laminate flooring as a ramp to make sure the cars were going the same speed when they reached the surfaces.

The less friction - the further our cars went. We could guess which surfaces were going to be good by feeling how smooth they were. There was excellent team work, measuring skills, recording skills and explaining going on. Well done P4!
