Forces and Magnets

This title supports the following learning objectives for Key Stage 2 science: Notice that some forces need contact between two objects, but magnetic forces can act at a distance; Observe how magnets attract or repel; Compare and group everyday materials on the basis of whether they are attracted to a magnet; Describe magnets as having two poles and predict whether two magnets will attract or repel each other, depending on which poles are facing; Explain that objects fall towards Earth because of gravity; Identify the effects of resistance and friction; Recognise that levers, pulleys and gears allow a smaller force to have a greater effect.
