Student lesson
- Moving air can push objects.
- Moving air is used in kites and sails.
- Windmills use moving air to do work.
- Bigger surfaces catch more air.
Words to know
a gentle wind
a sheet that catches wind to move a boat
a light frame flown on the wind
a machine with blades turned by wind
1. Discover: The kite day
On a windy afternoon, Kojo flies a kite on the school field. The kite lifts and pulls on the string. “The moving air is pushing it,” says his teacher. “It is a force you cannot see.”
Think: What keeps the kite up?
2. Understand: Moving air
Idea 1: Air pushes
Moving air is a push. It can move leaves, fly kites and push boats with sails.
Idea 2: Using wind
A windmill has blades that turn in wind. They can grind grain or pump water. Sailing boats use wind to travel across water.
Idea 3: Catching air
A big surface catches more air. A large sail pushes a boat more than a small one. A parachute is a big surface that slows a fall.
3. Worked examples
Example 1 (I show you): What moves it?
A sail boat.
- Wind pushes the sail.
- Boat moves.
- Moving air.
Answer: Moving air pushes the sail.
Example 2 (We do it together): Bigger sail
Large and small sails.
- Large catches more.
- More push.
- Faster boat.
Answer: Bigger sails catch more air.
Example 3 (You try): Parachute
A big canopy.
Show the steps and answer
- Catches air.
- Slows fall.
- Safe landing.
Answer: A parachute slows the fall.
Did you know?
Windmills in the Netherlands were used for centuries to pump water from low land.
Why this matters
Wind power helps people sail, travel and make energy.
4. Explore: Sail test
Make a paper sail on a foil boat and blow on it.
- Make a boat from foil.
- Fix a paper sail.
- Blow gently with a straw.
- Compare big and small sails.
Think about it: what did you notice?
What did you notice? The big sail moved the boat more.

If a learner struggles
- Find the misconception: “Wind is nothing.” It is moving air.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Explain how moving air pushes things.
- Guided practice: work through one example together and let the learner try the next one.
- Reassess: use the quiz again or the worksheet.
- Move on when the learner shows Silver-level evidence independently.
For parents and guardians
In this lesson your child learns how moving air does useful work. You do not need to be an expert to help.
- Fly a kite safely together.
- Ask, “What is pushing it?”
- Make a paper windmill.
- Ask “how do you know?” after each answer, and listen.
- Praise effort, not only right answers. Mistakes are how we learn.
- Ten to fifteen minutes a day is better than one long session.
Teacher package
1–5. Objectives, prerequisites, materials, preparation, duration
Lesson objectives. Learners will: say that moving air is a force; show objects pushed by air; explain sails and kites; test shapes in a breeze.
Prerequisite knowledge. Grade 1 ideas: weather and the sky, water around us and keeping our environment clean.
Materials. Foil, paper, straws, trays and water. Low-resource options: use chalk or charcoal on a board or wall, drawings in the sand, and objects from the classroom instead of printed materials.
Preparation. Prepare foil boats and sails. Prepare trays.
Suggested duration. 45–60 minutes. It can be split into two shorter sessions.
6–9. Teaching procedure, explanation notes, guided and independent activities
Introduction (5 min). Show a kite picture and ask, “What makes it fly?”
Explanation (10 min). Teach moving air.
Guided activity (10 min). Learners test sails.
Independent activity (10 min). Learners record.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. What is pushing it? Why?
Teacher explanation notes. Start with real objects and safe, hands-on observation. Then talk about what was seen, then draw and write. Always say “how do you know?”. Keep to the safety notes, and use local, safe materials.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use real objects and pictures, short sentences and a partner. Let learners point, show or draw instead of writing. Extension. Ask learners to find a new example at home and explain how they know.
Formative assessment. Listen to learners read and explain, ask “how do you know?”, and check the independent work.
Misconceptions. “Wind is nothing.” It is moving air.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz, the 9-mark exam practice and the worksheet on this page. All answers and marking guides are in the answer sections above. Re-check every answer before use.
16–19. Remediation, enrichment, homework, teacher reflection
Remediation. Explain how moving air pushes things. Enrichment. Look for one new example near your home or school, draw it and explain it to someone. Homework. See above.
Teacher reflection. After teaching, record: which ideas learners understood; which misconceptions occurred; which activities worked; which learners need more practice; and what to improve next time.
