Lesson Plan: Motion - Push and Pull
Grade: 3
Subject: Science
Duration: 30 minutes
Topic: Motion - Push and Pull
Objectives
By the end of this lesson, students will be able to:
- Define motion and identify examples of push and pull.
- Describe how pushes and pulls can change the movement of an object.
- Demonstrate the concepts of push and pull through hands-on activities.
Materials Needed
- Whiteboard and markers
- Chart paper
- Markers or crayons
- Toy cars or balls
- Ramps (made from cardboard or wooden boards)
- Weights (e.g., small bags of sand or rice)
- Push and pull activity cards (prepared as a worksheet)
Introduction (5 minutes)
-
Engage the Students:
- Begin with a short discussion on what motion means.
- Ask questions like:
- "What makes a car move?"
- "How do we move objects around us?"
-
Introduce the Topic:
- Explain that motion is changing position, and it can happen when we use force to push or pull objects.
Direct Instruction (10 minutes)
What is Push and Pull?
-
Push:
- Define "push" as applying force away from oneself.
- Provide examples: kicking a ball, pushing a shopping cart.
-
Pull:
- Define "pull" as applying force towards oneself.
- Provide examples: pulling a rope, drawing a wagon.
Effects of Push and Pull
- Explain how pushes and pulls can make objects start moving, stop moving, or change direction.
- Use examples to illustrate:
- Pushing a toy car makes it roll forward.
- Pulling a toy towards you makes it come closer.
Guided Practice (10 minutes)
-
Activity Setup:
- Divide students into small groups and give each group toy cars or balls, as well as ramps.
-
Experimentation:
- Instruct students to:
- Predict what will happen when they push or pull the toy cars down the ramps.
- Record their observations on chart paper.
- Discuss the results within their groups.
Independent Practice (5 minutes)
- Distribute the Push and Pull Activity Cards worksheet.
- Students will match pictures of push and pull actions with their definitions and draw their own examples.
Conclusion (5 minutes)
-
Review Key Concepts:
- Ask students to share their findings from the group activity.
- Summarize the key points about push and pull.
-
Exit Ticket:
- Have each student write one example of a push and one example of a pull on a sticky note and stick it on the board as they leave.
Assessment
- Observe group interactions during the experiment.
- Evaluate the completed worksheets for understanding of push and pull concepts.
- Review exit tickets for individual comprehension.
This lesson plan is aligned with the Next Generation Science Standards (NGSS) for Grade 3, focusing on physical science concepts related to forces and motion.
