Magnets: Attraction and RepulsionActivities & Teaching Strategies
Active learning lets students feel magnetic forces firsthand rather than memorise rules. Handling real objects turns the invisible forces of attraction and repulsion into observable evidence students can trust and describe.
Learning Objectives
- 1Classify a range of common materials as magnetic or non-magnetic based on experimental results.
- 2Explain the phenomenon of magnetic attraction and repulsion, referencing the interaction of magnetic poles.
- 3Compare the magnetic strength of different bar magnets by designing and conducting a fair test.
- 4Predict whether an object will be attracted to a magnet based on its material composition.

Sorting Station: Magnetic Materials
Provide trays with objects like paperclips, plastic spoons, coins, and wood blocks. Students predict, test with magnets, and sort into magnetic and non-magnetic piles. Groups record findings in a class chart and discuss surprises.
Prepare & details
Differentiate between magnetic and non-magnetic materials.
Facilitation Tip: During Sorting Station, hand each pair a labelled tray so every object has a clear place and students can rotate roles without crowding.
Setup: Groups at tables with access to source materials
Materials: Source material collection, Inquiry cycle worksheet, Question generation protocol, Findings presentation template
Pairs Activity: Pole Investigation
Give each pair two bar magnets marked N and S. Students bring poles together to observe attract or repel, then test predictions with hidden magnets under cloth. Record results in a table showing like versus unlike poles.
Prepare & details
Explain how two magnets can attract or repel each other without touching.
Facilitation Tip: For Pole Investigation, give each pair two bar magnets and a simple table to record which ends attract or repel before they draw conclusions.
Setup: Groups at tables with access to source materials
Materials: Source material collection, Inquiry cycle worksheet, Question generation protocol, Findings presentation template
Experiment Design: Magnet Strength
Students choose variables like distance or magnet type, then design a fair test using a ruler and paperclips to measure pull. Pairs conduct trials, average results, and present to the class.
Prepare & details
Design an experiment to test the strength of different magnets.
Facilitation Tip: Set clear rules for the Magnet Strength fair test: same paperclip size, same starting gap, and five measured trials before students choose their strongest magnet.
Setup: Groups at tables with access to source materials
Materials: Source material collection, Inquiry cycle worksheet, Question generation protocol, Findings presentation template
Timeline Challenge: Magnetic Maze
Hide iron filings or paperclips under paper; students guide a magnet from above to navigate a drawn maze. Switch roles and time attempts to compare strengths.
Prepare & details
Differentiate between magnetic and non-magnetic materials.
Setup: Long wall or floor space for timeline construction
Materials: Event cards with dates and descriptions, Timeline base (tape or long paper), Connection arrows/string, Debate prompt cards
Teaching This Topic
Teach magnets through touch and talk: students need to hold objects, feel pulls without seeing the gap, and use precise terms like ‘pole’ and ‘repel.’ Avoid over-explaining; let evidence from their tests drive understanding. Research shows concrete experience outweighs abstract rules for retention at this age.
What to Expect
Students will confidently classify materials, explain pole behaviour with correct vocabulary, and design fair tests. They will articulate that magnets attract specific metals over a distance and that poles behave predictably.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Sorting Station, watch for students labelling all metals as magnetic.
What to Teach Instead
Encourage students to test each metal object one at a time, grouping only those that clearly cling to the magnet. Use the non-attracted group to highlight that most metals like aluminium and copper are not magnetic.
Common MisconceptionDuring Pole Investigation, watch for students assuming only attraction is possible.
What to Teach Instead
Have students switch magnet ends repeatedly and record both outcomes. Ask them to use the words ‘attract’ and ‘repel’ aloud as they feel the push, reinforcing that magnets can both pull and push.
Common MisconceptionDuring Experiment Design: Magnet Strength, watch for students claiming magnets must touch to work.
What to Teach Instead
Ask students to measure the exact gap where the magnet still pulls a paperclip. By quantifying the distance, they see the force acts through space, making the invisible force visible.
Assessment Ideas
After Sorting Station, provide a mixed set of small objects. Ask students to sort them into ‘Magnetic’ and ‘Non-magnetic’ groups and write one sentence explaining their classification criteria.
During Pole Investigation, hold up two bar magnets and ask students to describe what happens when like poles face each other and when opposite poles face each other. Encourage them to use the terms ‘attract’ and ‘repel’ and explain why the poles behave differently.
After Experiment Design: Magnet Strength, present students with a scenario: ‘A metal key is buried under a thin layer of soil. Will a strong magnet find it if the key is aluminium? Explain your reasoning based on what you learned about magnetic attraction.’
Extensions & Scaffolding
- Challenge: Ask students to design a second fair test comparing magnet shape or thickness, then present their method and results to the class.
- Scaffolding: Provide a word bank with ‘attract,’ ‘repel,’ ‘pole,’ and ‘ferromagnetic’ on cards for students to place under objects during Sorting Station.
- Deeper exploration: Introduce a mini-investigation on magnetic fields using iron filings on overhead sheets to reveal the full field shape around each magnet type.
Key Vocabulary
| Magnet | An object that produces a magnetic field, capable of attracting or repelling certain materials. |
| Magnetic material | A material that is attracted to magnets, typically containing iron, nickel, or cobalt. |
| Non-magnetic material | A material that is not attracted to magnets, such as wood, plastic, or aluminum. |
| Attract | The force that pulls two magnets or a magnet and a magnetic material together. |
| Repel | The force that pushes two magnets apart when their like poles are brought near each other. |
| Magnetic pole | The ends of a magnet where the magnetic force is strongest, usually labeled North and South. |
Suggested Methodologies
Planning templates for Science
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
RubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.
