Year 5 Science – Friction

Year 5 have been investigating friction in their science lesson this week. They investigated how friction creates heat by rubbing their hands together and found that the harder they rubbed, the more heat was produced. They also watched as Mr Stead did the handkerchief and cup experiment:

Then the children completed their own friction experiments to see how much force it took to move a wooden block along different surfaces. The children found that the surface with the least friction was the table top (plastic laminate) and the surface with the most friction was the sandpaper.
