Student lesson
- Magnets attract some metals.
- The force works at a distance.
- It can pass through paper, wood and plastic.
- It is strongest at the ends (poles).
Words to know
an object that attracts some metals
the force a magnet exerts
a force that works without touching
the space around a magnet where its force acts
1. Discover: The jumping paper clip
Nii holds a magnet above a paper clip on a table. The clip jumps up and sticks. “It moved without touching,” he says. “That is a magnetic force. It works through the air.”
Think: What else could a magnet pull through?
2. Understand: Magnetic force
Idea 1: What is a magnet?
A magnet attracts some metals like iron. Its pull is called a magnetic force.
Idea 2: Non-contact
Magnetic force is a non-contact force. It works without touching, in the field around the magnet, and can pass through paper, wood and plastic.
Idea 3: Strength
A magnetic force is strongest at the poles, the ends of the magnet. Stronger magnets can pull from further away.
3. Worked examples
Example 1 (I show you): Distance
Clip jumps.
- No touch.
- Force.
- Magnetic.
Answer: Magnetic force acts at a distance.
Example 2 (We do it together): Through
Paper in between.
- Still pulls.
- Through paper.
- Yes.
Answer: Magnetism passes through paper.
Example 3 (You try): Strong
Ends.
Show the steps and answer
- Poles.
- Strongest.
- Ends.
Answer: The poles are strongest.
Did you know?
Earth itself acts like a giant magnet, which is why compasses work.
Why this matters
Magnets are used in doors, speakers, motors and tools.
4. Explore: Magnet through materials
Test whether magnetic force passes through materials.
- Put a paper clip on a table.
- Place paper, card, plastic between.
- Move the magnet under.
- Record if it moves.
Think about it: what did you notice?
What did you notice? The force passed through many materials.

Courseversity badge thresholds (overall quiz score): Gold = 90–100%; Silver = 80–89.9%; Bronze = 70–79.9%. A badge is never a full record of progress.
If a learner struggles
- Find the misconception: “Magnets only work when touching.” They act at a distance.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Explain magnetic force.
- 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 tests magnetic forces. You do not need to be an expert to help.
- Play with a safe magnet.
- Ask, “What does it pull?”
- Keep magnets away from cards.
- 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: describe a magnetic force; show it acts at a distance; test through materials; compare magnet strength.
Prerequisite knowledge. Grade 2 force ideas: pushes and pulls, simple machines and how forces change movement.
Materials. Classroom magnets, paper clips, card, plastic, wood. 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. Check magnet strength.
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). Pull a clip up with a magnet and ask, “What is happening?”
Explanation (10 min). Teach magnetic force.
Guided activity (10 min). Learners test.
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. Does the force pass through? Where is it strongest?
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. “Magnets only work when touching.” They act at a distance.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz, the 10-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 magnetic force. 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.
