Study Guides
This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
This unit introduces knowledge of simple rotary mechanisms that create movement. Pupils will investigate how windmills work, consider sail design, and produce a working model that will be tested for stability and movement.
Lesson Summary
You will learn to describe how wind is useful.
Key Notes
- Windmills have sails or blades which turn.
- Windmills use wind to produce electricity or pump water.
- Windmills use wind to grind wheat into flour.
Vocabulary To Learn
- rotary motion: something that turns around in circles
- sails: parts of a windmill that turn in the wind
- blades: parts of a wind turbine that turn in the wind
- millstone: a heavy stone that grinds grain to make flour
Common Mistakes To Avoid
- Windmills create wind, rather than being moved by it.
3 Quick Questions (With Answers)
1. Explain the lesson in two key points.
Windmills have sails or blades which turn. Windmills use wind to produce electricity or pump water.
2. What does this key word mean in this lesson? 'rotary motion'
something that turns around in circles.
3. Correct this common mistake.
Mistake: Windmills create wind, rather than being moved by it. Correction: The wind pushes the windmill's blades to make them turn.
