We wondered what would happen if we tried to move objects across different surfaces. The children chose to pull an object across surfaces including the carpet, the table, the whiteboard and the corridor. They measured their results in Newtons using a force meter. We found out that the rougher a surface was the more force we needed to apply in order to move the object. When a surface was smooth it needed less force to move the object, as there was less friction.
