S2.5.1 For the adult
Forces are pushes and pulls
What makes a thing start to move, or stop?
What this chapter teaches
A force is a push or a pull. An arrow shows its direction, and a longer arrow shows a bigger force. Forces can start, stop, speed up, slow down or turn a thing, and they can change its shape. A still thing has forces on it too, and they balance.
Three questions to ask
There is no one right wording. Listen for the idea.
- What is a push and a pull that you use at home?
- A book lies on a table. What forces are on it?
- How can a force change the shape of a thing?
After the chapter, the learner can
- Draw arrows to show the direction of a push or a pull
- Explain that forces can change speed, direction and shape
What they copy into their notebook
A force is a push or a pull. An arrow shows its way. A longer arrow is a bigger force. Forces can change speed, direction and shape. A still thing has balanced forces.
