Lesson Plan: Introduction to Levers

Subject: Design and Technology

Grade: Year 3

Duration: 30 minutes

---

Learning Objectives

By the end of this lesson, students will be able to:

• Understand the basic concept of levers.
• Identify the three different parts of a lever: the fulcrum, the load, and the effort.
• Describe how levers help us lift heavy objects.

---

Materials Required

• A simple lever model (made from a ruler and a small block for the fulcrum)
• Different weights (e.g., books, small bags of rice or beans)
• Whiteboard and markers
• Worksheets for drawing levers
• Interactive online resources or videos (optional)

---

Lesson Structure

Introduction (5 minutes)

Begin the lesson by asking students if they have ever used a seesaw or a bottle opener. Discuss briefly how these objects work using levers.

• Key Question: "What do you think a lever is?"
• Encourage students to share their thoughts.
• Introduce the term "lever" and explain its purpose.

Explanation of Levers (10 minutes)

1. Parts of a Lever

   • Fulcrum: The point where the lever pivots.
   • Load: The weight or resistance that is lifted.
   • Effort: The force applied to lift the load.

2. Types of Levers

   • First Class: Fulcrum is in the middle (e.g., seesaw).
   • Second Class: Load is in the middle (e.g., wheelbarrow).
   • Third Class: Effort is in the middle (e.g., tweezers).

3. Demonstration using the Model

   • Set up the simple lever model using a ruler and block.
   • Show how moving the fulcrum affects the effort needed to lift the load.

Hands-On Activity (10 minutes)

1. Group Activity:

   • Divide the class into small groups.
   • Provide each group with the lever model and different weights.
   • Ask them to experiment by changing the position of the fulcrum and record their observations on how it affects the effort needed to lift the load.

2. Discussion:

   • After the activity, regroup and discuss findings.
   • Ask each group to share how they adjusted the fulcrum and what effect it had on lifting the load.

---

Conclusion (5 minutes)

1. Recap Key Concepts:

   • Briefly review what a lever is and its components.
   • Ask students to recall the three types of levers.

2. Exit Ticket:

   • Hand out worksheets where students can draw their own lever and label its parts.
   • As they finish, encourage them to think of real-life examples of levers they encounter at home or in school.

---

Assessment

• Observe student participation during activities and discussions.
• Review completed worksheets to assess understanding of lever components and types.

---

Extension Activity (Optional)

For students who finish early, provide them with a fun challenge:

• Ask them to design a simple machine that uses a lever and describe how it works.

---

Resources

• Interactive video on levers
• Online games related to simple machines
• Library books on levers and simple machines

---

This lesson encourages engagement and curiosity while providing foundational knowledge about levers. It incorporates visual, auditory, and kinesthetic learning styles for effective understanding.
