Objective
By the end of this lesson, you will be able to observe the way objects move and understand how changes in motion are related to push and pull forces.
Materials and Prep
- Various objects of different shapes and sizes (e.g., toy cars, balls, blocks)
- A clear space for movement
Activities
- Activity 1: Rolling Objects - Roll different objects on a smooth surface and observe how they move. Discuss what makes them move and how they stop.
- Activity 2: Push and Pull - Use your hands to push and pull objects of various sizes and weights. Observe how the objects respond to the force applied.
- Activity 3: Tug of War - Find a partner and play a simple game of tug of war using a rope or a long piece of fabric. Observe how the force applied by each person affects the movement of the rope.
- Activity 4: Experiment with Balloons - Blow up a balloon and let it go without tying it. Observe how it moves and discuss what forces are acting on it.
Talking Points
- "Objects can move in different ways. They can roll, slide, or be pushed or pulled."
- "When we push something, we use force to move it away from us. When we pull something, we use force to bring it closer to us."
- "The size and weight of an object can affect how it moves when we push or pull it. Heavier objects may be harder to move."
- "When we play tug of war, we are using force to try and move the rope. The stronger force will make the rope move in that direction."
- "When we let go of a blown-up balloon, it moves because the air inside pushes it forward."
