Year 3 – Friction

This afternoon, Year 3 investigated friction.  We set up a fair test investigation where we looked at what material would cause the most friction and slow the car down the most.  We all made predictions before we started and we all had a different idea about which material would cause the most frictions.  We set up a ramp and either covered it in sand, a towel, corrugated cardboard or didn’t cover it at all (wood).  We found that the sand caused the most friction as the car hardly moved down the ramp at all.
