Year 2 materials – fact or friction?

Year 2 have been looking at different materials and their properties. This week we tackled the issue of friction! We have planned an experiment to determine what material would be best to slow down a younger child who was afraid of going too fast down a slide. We even managed to test out some materials ourselves before our experiment next week. Can you predict what happened when we sat on sponges at the top of the slide in the playground?
