Lesson Content

Meaning And Examples Of Levers

A lever is a simple machine that helps us lift or move heavy objects with less effort. It consists of a rigid bar that pivots around a fixed point called the fulcrum.

Examples of simple levers include:

1. See-Saw: A playground equipment where a long board is balanced in the middle.
2. Pliers: A hand tool used to grip and bend objects.
3. Can Opener: A tool used to open cans.
4. Crowbar: A tool used for prying and lifting heavy objects.
5. Scissors: A tool used for cutting paper and other materials.

Lesson Evaluation:

To evaluate the learning, the teacher asks pupils to:

1. Define a lever.
2. Name three examples of simple levers.
3. Explain how a see-saw works as a lever.
4. Identify the fulcrum in a pair of pliers.
