Activity 01
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.
Differentiate between magnetic and non-magnetic materials.
Facilitation TipDuring Sorting Station, hand each pair a labelled tray so every object has a clear place and students can rotate roles without crowding.
What to look forProvide students with a collection of small objects (e.g., paperclip, coin, eraser, key, foil wrapper). Ask them to sort the objects into two groups: 'Magnetic' and 'Non-magnetic', and write one sentence explaining their classification criteria.

Activity 02
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.
Explain how two magnets can attract or repel each other without touching.
Facilitation TipFor Pole Investigation, give each pair two bar magnets and a simple table to record which ends attract or repel before they draw conclusions.
What to look forHold up two bar magnets. Ask students: 'What do you observe happening when I bring these ends together? What about these ends? Can you use the terms 'attract' and 'repel' to describe what you see? What do you think is happening inside the magnets to cause this?'

Activity 03
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.
Design an experiment to test the strength of different magnets.
Facilitation TipSet clear rules for the Magnet Strength fair test: same paperclip size, same starting gap, and five measured trials before students choose their strongest magnet.
What to look forPresent students with a scenario: 'A treasure chest is buried under a thin layer of sand. You have a strong magnet. What material would the treasure likely need to be made of for the magnet to find it? Explain your reasoning.'

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.
Differentiate between magnetic and non-magnetic materials.
What to look forProvide students with a collection of small objects (e.g., paperclip, coin, eraser, key, foil wrapper). Ask them to sort the objects into two groups: 'Magnetic' and 'Non-magnetic', and write one sentence explaining their classification criteria.

Generate Complete Lesson→A few notes on teaching this unit
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.
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.
Watch Out for These Misconceptions
During Sorting Station, watch for students labelling all metals as magnetic.
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.
During Pole Investigation, watch for students assuming only attraction is possible.
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.
During Experiment Design: Magnet Strength, watch for students claiming magnets must touch to work.
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.
