Lesson Planning
Teaching
- Investigate how levers work. Explore how the position of fulcrum, load and effort impacts on use.
- Investigate how pulleys work and how the number of pulleys used changes the effort required.
- Draw diagrams that explain the forces, loads, weights and efforts for levers and pulleys.
Activities
- Investigate how levers work and how the position of the fulcrum impacts on its effectiveness.
- Scale weights and lengths.
- Investigate how pulleys work and note the correlation between effort required and the number of pulleys.
- Set out instructions for forces on the ground to help them implement findings from investigations.
Investigation - problem solving/fair testing
Investigate and create levers.
Investigate and create pulleys.
