Student lesson

The lesson in 60 seconds

  1. Magnetic materials are attracted by magnets.
  2. Iron and steel are magnetic.
  3. Many metals, like aluminium and copper, are not.
  4. Plastic, wood and glass are non-magnetic.

Words to know

magnetic
attracted by a magnet
non-magnetic
not attracted by a magnet
iron
a metal that is magnetic
steel
a mix of iron and other materials

1. Discover: The tin and the can

Selma tests a steel can and an aluminium drink can with a magnet. The steel can sticks. The aluminium can does not. “Both are metal,” she says. “But only one is magnetic!”

Think: Why do the two metals behave differently?

2. Understand: Magnetic materials

Idea 1: Magnetic or not

A material is magnetic if a magnet attracts it. Iron and steel are magnetic. Plastic, wood, glass and paper are non-magnetic.

Idea 2: Metals differ

Not all metals are magnetic. Aluminium, copper, gold and silver are not attracted by a magnet.

Idea 3: Testing

Hold a magnet near each object and see if it is pulled. Record results in a table. Test one object at a time.

Remember: Iron and steel are magnetic. Many metals are not. We test objects with a magnet and sort them.

3. Worked examples

Example 1 (I show you): Test

Nail.

  1. Iron.
  2. Pulled.
  3. Magnetic.

Answer: A nail is magnetic.

Example 2 (We do it together): Test

Coin.

  1. Many coins.
  2. Not pulled.
  3. Non-magnetic.

Answer: Many coins are not magnetic.

Example 3 (You try): Sort

Wood.

Show the steps and answer
  1. Not pulled.
  2. Non-magnetic.
  3. Sorted.

Answer: Wood is non-magnetic.

Did you know?

Only a few metals are strongly magnetic: iron, nickel and cobalt.

Why this matters

Knowing magnetic materials helps recyclers separate steel from other metals.

4. Explore: Magnetic sort

Test ten objects and sort them.

  1. Collect ten safe objects.
  2. Predict which will be magnetic.
  3. Test each with a magnet.
  4. Sort into two groups.
Think about it: what did you notice?

What did you notice? Not all metals were magnetic.

Safety first: Use only safe, blunt objects. Keep magnets away from phones, cards and computers. Never put small objects or magnets in the mouth.

5. Practise

Say it in a sentence

Use these starters when you talk about the lesson. Say them out loud.

  • A ___ material is attracted by a magnet.
  • Iron and ___ are magnetic.
  • Plastic is ___.
  • We ___ objects with magnets.

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

  1. Find the misconception: “All metals are magnetic.” Only some.
  2. Explain another way: use real objects, pictures or actions first, then words.
  3. Show a simpler example: Sort magnetic and non-magnetic materials.
  4. Guided practice: work through one example together and let the learner try the next one.
  5. Reassess: use the quiz again or the worksheet.
  6. Move on when the learner shows Silver-level evidence independently.

For parents and guardians

In this lesson your child tests which materials are magnetic. You do not need to be an expert to help.

  • Test things at home safely.
  • Ask, “Will it stick?”
  • 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: define magnetic material; test objects with a magnet; sort magnetic and non-magnetic; explain that not all metals are magnetic.

Prerequisite knowledge. Grade 2 force ideas: pushes and pulls, simple machines and how forces change movement.

Materials. Magnets, objects, tables, pencils. 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. Collect safe objects.

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). Hold up a nail and a coin and ask, “Which will stick?”

Explanation (10 min). Teach magnetic materials.

Guided activity (10 min). Learners test.

Independent activity (10 min). Learners sort.

Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.

Key questions. Is it magnetic? How do you know?

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. “All metals are magnetic.” Only some.

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. Sort magnetic and non-magnetic materials. 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.
