By the end of the lesson, the learner should be able to:

- Identify common levers used in day to day life
- Demonstrate the use of common levers
- Appreciate the role of levers in making work easier

In groups, learners are guided to:
- Visit a playground to identify and play on a see-saw
- Demonstrate the use of simple items like bottle openers, scissors, spoons, and spades
- Discuss how these items make work easier
