Science - Feeling Friction

We researched what friction is (two surfaces rubbing together to cause heat). We had to decide whether rubbing our hands together normally or rubbing our hands together with detergent would make heat quicker.

Our class was divided in our hypothesis. We timed it and found that rubbing our hands together without detergent created heat more quickly, because with detergent our hands were smoother and a smoother surface takes longer to cause friction.
