This clip compilation could be used as an introduction to a lesson exploring forces. The children could be asked to watch the video and note down as many examples of pushes and pulls as possible, sorting them into two distinct groups. Can they add any more examples to their lists? The clip also provides a useful springboard to examine how much force it takes to move an object from a stationary position. In class, the children could experiment with a weighted plastic tub and a forcemeter/ newtonmeter to explore how much force is required to start the tub moving. Does it require as much force to 'push' or 'pull' the weighted object? Clearly, this experiment can be developed into a variety of design tasks. Does the tub require more force to start moving on different surfaces? What happens if heavier weights are added?
