In our Science unit this half term, we are exploring forces and magnets. We have learnt that we need forces to make things move, and that a force can be a push or a pull. We can make things move faster, slower or even make them stop if the size of the force changes. Different surfaces can also affect how forces act on moving things, which brings us to our most recent lesson, where we received a very exciting letter! 

We set to work to investigate friction, and how it affects the motion of an object. We know that friction works against the motion in the opposite direction. We worked in small teams to find which surface was best for toy cars. We did this by constructing ramps and measuring how far our toy car travelled on different surfaces. These surfaces included wood, rubber, plastic, cardboard, wool, bubble wrap and fabric! We are planning to use our findings to explain which surface is best for toy cars.
