They help from the laws of physics, we know about how they attract may remember that children can investigate action- and repel each other. Give at-a-distance forces. Begin the children some magnets to forces are ‘pushes’ by thinking about ‘contact’ or investigate and remind them and ‘pulls’, can make ‘applied’ forces. Read the part of the forces between these. things move or change in the book where Matilda Magnetism is a non-contact speed or direction, or knocks over a glass of water force – it can move something that they can change with her mind (download this like a paperclip at a distance the shape of some objects.

We know that forces can move objects, Explain that we can Think now about weight and physically touch objects and how gravity pulls two objects but can they really be moved without being touched? use that force to make them together without contact; you Watch the clip from the 1996 film where Matilda moves move.
