Pupils identify where friction is occurring in a number of photographs. They say whether the moving objects have been designed to create high or low friction and why.
Learning Objectives:
PoS - identify the effects of air resistance, water resistance and friction, that act between moving surfaces
NaG - pupils should experience forces that make things begin to move, get faster or slow down
WS - pupils should identify scientific evidence that has been used to support or refute ideas or arguments
