### Lesson Plan: Understanding Force
**Subject:** Basic Science and Technology
**Grade Level:** Primary 3
**Duration:** 60 minutes
**Topic:** Force
---
#### Objectives:
- Define force.
- Identify different examples of force in everyday life.
- Understand how force can change the motion of an object.
#### Materials:
- Ball
- Toy cars
- String
- Weights or differently sized objects (blocks, books, etc.)
- Pictures or videos showing different forces (wind, water, gravity)
- Worksheets
- Board and markers
#### Introduction (10 minutes):
1. **Greeting and Warm-Up (2 minutes):**
- Greet the students.
- Engage them in a short warm-up activity like clapping hands in patterns to stimulate attention.
2. **Introduction to Topic (8 minutes):**
- Write "Force" on the board.
- Ask students if they have ever heard the word "force" and what they think it means.
- Briefly explain that force is a push or a pull on an object.
- Show quick examples like pushing a door to open it and pulling a drawer to close it.
#### Instruction and Demonstration (20 minutes):
1. **Explaining Forces (10 minutes):**
- Define force clearly: "A force is a push or a pull that can change the motion of an object."
- Illustrate by using a ball; push it (shows force causes movement) and pull a toy car with a string.
- Explain the two main types of forces: pushes and pulls.
2. **Examples in Everyday Life (10 minutes):**
- Show pictures or short videos of everyday forces: wind pushing a kite, water pulling at boats, gravity pulling us to the ground.
- Conduct a small demonstration with weights: lift a light object (easy to pull up) and a heavy object (requires more force).
#### Guided Practice (15 minutes):
1. **Activity - Identifying Forces (10 minutes):**
- Divide students into small groups.
- Give each group different objects (balls, toy cars, books).
- Ask them to experiment with pushing and pulling these objects and observe what happens.
2. **Discussion and Sharing (5 minutes):**
- Bring the class back together.
- Have each group share what they observed.
- Highlight different forces they used (push/pull) and how objects moved differently based on the force applied.
#### Independent Practice (10 minutes):
1. **Worksheet Activity:**
- Distribute worksheets that have pictures of different scenarios (e.g., a child kicking a ball, a person pulling a cart).
- Instruct students to identify which scenario shows a push and which shows a pull.
- Write a sentence explaining the force in each scenario.
#### Conclusion (5 minutes):
1. **Review and Recap:**
- Summarize the key points: What is a force, types of forces (push and pull), and examples.
- Ask a few questions to review, such as “What happens when you push a toy car?” “Can you name a force we can find in nature?”
2. **Closing (2 minutes):**
- Praise the students for their participation and effort.
- Mention that they will continue to explore more about forces and their effects in future lessons.
#### Assessment:
- Observation during group activities to ensure participation and understanding.
- Completion and accuracy of the worksheet.
- Responses during the conclusion questions.

### Additional Notes:
- Ensure the activities are conducted safely, especially when handling heavier weights.
- Facilitate and guide group discussions to maintain focus and encourage all students to contribute.
- Adjust lesson duration depending on students' engagement and interest levels.
