This week’s Science lesson in UKS2 was a total drag… literally! The children learned about the force of friction. They conducted an experiment to test how much friction is produced by different materials. Using a Newton meter, the children measured the force used to drag a weighed-down plastic tray along several materials. To make sure their results were accurate, each material was tested three times and in order for it to be a fair test, a control surface (the table) was tested too.
