Our new topic this half term is magnets and forces. We started by looking at the push and full force and today explored friction. We set up an investigating to see the amount of friction created by different surfaces. We have learnt that the amount of friction created by an object moving over a surface depends on the roughness of the surface and the object, and the force between them. We each made a prediction and recorded our results in a table. At the end we wrote a good conclusion about what we have found out.
