Learning Objectives

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

• Define what a force is and explain how forces act on objects.
• Identify different types of forces, such as push, pull, friction, gravity, and air resistance.
• Observe and categorise forces in their surroundings through hands-on activities.

Key Vocabulary

✅ Force
✅ Contact force
✅ Non-contact force
✅ Gravity
✅ Friction
✅ Air resistance
✅ Push & Pull

Lesson Structure

1. Starter Activity: The Invisible Push (10 mins)

Objective: To spark curiosity about forces.

• Begin with a class demonstration: Hold a small foam ball and ask, “What happens when I push the ball?”
• Let students share their thoughts. Then ask: “What happens if I drop the ball? Why does it move?”
• Introduce the idea that forces are all around us and lead into today’s lesson focus.

Mini Investigation:

• Give each student a small object (eraser, toy car, sponge, etc.).
• Ask them to experiment with pushing, pulling, and dropping it.
• Let them describe what they observe in pairs.

2. Teacher Explanation & Discussion (15 mins)

Objective: To establish the foundational knowledge of forces.

• What is a Force? (Explain that a force is a push or pull that moves or changes an object’s motion.)
• Types of Forces: Introduce
  • Contact Forces (e.g., friction, pushing a door open)
  • Non-contact Forces (e.g., gravity pulling us down)
• Real-Life Examples:
  • Walking (friction helps us move forward).
  • Dropping a pencil (gravity pulls it down).
  • Airplane flying (air resistance acts against it).

3. Hands-On Investigation: Force Detectives (20 mins)

Objective: To identify different forces in action.

• Set Up: Give each pair a Forces Observation Sheet.
• Instructions:
  1. Assign different classroom objects and actions (e.g., opening a door, sliding a book, jumping in place).
  2. Ask students to observe what happens and write down the forces involved.
  3. Pairs discuss and categorise forces into Push, Pull, Friction, Gravity, or Air Resistance.

Challenge:

• Can they find an example of a contact and non-contact force?

4. Mini Experiment: The Mystery of Friction (10 mins)

Objective: To explore how friction affects motion.

• Materials: A toy car, smooth surface (plastic tray), rough surface (sandpaper).
• Process:
  1. Push the car on the smooth surface—observe how far it travels.
  2. Push it again on sandpaper—compare the distance.
  3. Discuss why friction slowed it down.

5. Plenary: Forces in the Real World (5 mins)

Objective: To reinforce learning and encourage real-world connections.

• Ask: “Where do you experience forces every day?”
• Students share real-life examples (cycling, kicking a football, using brakes on a bike).
• Quick-fire quiz:
  • What type of force pulls objects down? (Gravity)
  • What happens if we didn’t have friction? (Slipping everywhere)

Exit Reflection: One-word summary—each student chooses one word that best describes what they learned today.

Assessment for Learning

✅ Observation: Check understanding as students discuss forces in pairs.
✅ Forces Observation Sheets: Ensure students correctly categorise forces.
✅ Questioning: Use real-world questions to assess comprehension.

---

Differentiation Strategies

• Support: Provide sentence starters (e.g., "I noticed that when I push the car, it...").
• Challenge: Ask higher-level students to think about combining forces (e.g., what happens when you push a ball uphill?).

---

Resources & Materials

• Foam balls / toy cars
• Small classroom objects (erasers, books, etc.)
• Smooth and rough surfaces
• Forces Observation Sheets

Teacher Reflection (Post-Lesson)

• Which activities engaged students the most?
• Did students grasp the concept of forces?
• What adjustments could enhance future lessons?
