Move the Teacher
- Discrepant Event (Investigatable)
10 mins. (or however long it takes!)
- Forces and Motion
We use rollers or wheels to help us move things. How can we use them to help us move someone, like your teacher, while they're sitting on a board?
The sliding friction of the board against the floor is much greater than the rolling friction of cylinders against the floor. That's why it is much easier to pull someone using cylindrical 'rollers' - there is less friction.
In this activity, students work together to move their teacher (or another adult) using only a board and rolling cylinders.
