Lesson Details
Key learning points
- Mechanisms are systems that make something move and can include levers.
- Levers are rigid bars that help lift or move things by turning on a pivot point.
- Levers can be made using card and split pins.
Common misconception
A lever is just a seesaw mechanism and only moves up and down.
Levers move up and down and the end of the lever moves in a curved direction. Levers can be turned for different effects.
