We have been doing a unit about force. Force is when you move something with a push or pull. And we have been learning about friction. Friction helps you do everything except when you're trying to have fun like slides,roller skating, ice skating, and much more. We do an experiment to find out if wax paper, sand paper, fabric, or a table had more friction. The sandpaper had the most and the wax paper had the least.
It was very fun we came up with a lot of ideas to make different ramps.
