Slippery shoes!

In Science Club this week we investigated which type of shoes are the least slippery. Each group tested a different surface (wooden, plastic and carpet) and six different types of shoes. We placed shoes on ramps and measured how many books it took to prop up the ramp before the shoe slid. As scientists we thought about how we could make our investigation fair by only changing one thing (type of shoes) and keeping everything else the same (the size of shoe) then made predictions about which shoe we thought would have the most and least friction on each surface, explaining why we thought this. Some of our results really surprised us!

After our investigation we compared our results and found that the best surface to create friction was carpet and some of the best shoes were trainers, pumps or sandal depending on the surface.

Ruby: I was surprised that the black boot took 20 books to slide on the wood!"

Alice: I was surprised that the PE pump only book 4 books to slide."

Alistair: "I learnt a new word 'Friction' and was shocked that the PE shoe slid so quickly."
