Magnetic ForcesActivities & Teaching Strategies
Active learning helps Year 3 students grasp magnetic forces because concrete, hands-on experiences turn abstract ideas into visible outcomes. Students see repulsion, attraction, and strength differences when they manipulate real objects, making the invisible force tangible and memorable.
Learning Objectives
- 1Classify a range of everyday materials as magnetic or non-magnetic based on experimental results.
- 2Compare the strength of different magnets by measuring the distance at which they attract or repel objects.
- 3Explain the concepts of magnetic attraction and repulsion as non-contact forces.
- 4Design and conduct a simple experiment to investigate the properties of magnets.

Stations Rotation: Magnet Testing Stations
Prepare four stations: one for attraction (lift paperclips with various magnets), repulsion (push floating magnets in water), strength comparison (measure drop distances), and materials sort (test classroom items). Groups rotate every 10 minutes, draw predictions, test, and record results in tables.
Prepare & details
Explain how magnets can attract or repel without touching.
Facilitation Tip: During Magnet Testing Stations, place a mix of magnetic and non-magnetic items at each station and have students record predictions before testing to reveal prior knowledge gaps.
Setup: Tables/desks arranged in 4-6 distinct stations around room
Materials: Station instruction cards, Different materials per station, Rotation timer
Pairs: Pole Identification Challenge
Provide bar magnets and compass needles. Pairs mark north and south poles by observing deflection, then test attractions and repulsions between magnets. They create a class chart of predictions versus outcomes.
Prepare & details
Compare the strength of different magnets.
Facilitation Tip: For the Pole Identification Challenge, give each pair two bar magnets and ask them to mark the poles with stickers before testing interactions to build ownership of their findings.
Setup: Tables/desks arranged in 4-6 distinct stations around room
Materials: Station instruction cards, Different materials per station, Rotation timer
Small Groups: Design a Fair Test
Groups choose two magnets and design an experiment to compare strengths, such as maximum paperclips lifted or distance of attraction. They list variables to control, conduct trials, and present findings to the class.
Prepare & details
Design an experiment to test which materials are magnetic.
Facilitation Tip: While students Design a Fair Test, circulate with a clipboard to note whether they control variables like distance or object size, gently guiding those who change multiple factors at once.
Setup: Tables/desks arranged in 4-6 distinct stations around room

Whole Class: Magnetic Fishing Game
Hide magnetic and non-magnetic objects in a tub of shredded paper. Students take turns 'fishing' with string-tied magnets, classify catches, and discuss why some items were attracted.
Prepare & details
Explain how magnets can attract or repel without touching.
Facilitation Tip: In the Magnetic Fishing Game, assign roles like recorder or fisher to ensure all students participate and discuss their observations as a group.
Setup: Tables/desks arranged in 4-6 distinct stations around room

Teaching This Topic
Teach magnetic forces by starting with what students already know, then let them test their ideas through structured experiments. Avoid explaining everything upfront—instead, let observations lead the discussion so students confront misconceptions themselves. Research shows this approach builds deeper understanding than lectures alone.
What to Expect
Successful learning looks like students accurately identifying magnetic materials, predicting pole interactions, and explaining why force changes with distance. They should use terms like attraction, repulsion, and fair test while designing simple experiments with clear evidence.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Magnet Testing Stations, watch for students assuming all metals are magnetic, especially when testing coins or aluminium foil.
What to Teach Instead
Provide a variety of metals at the station, including copper, aluminium, steel, and iron. Ask students to predict and test each one, then discuss why only some respond to the magnet.
Common MisconceptionDuring Pole Identification Challenge, watch for students believing a single-letter marking is enough to identify poles.
What to Teach Instead
Have students test their marked poles with another magnet and observe attraction or repulsion. Ask them to refine their labels based on results, reinforcing that poles must be verified through interaction.
Common MisconceptionDuring Design a Fair Test, watch for students thinking magnetic force never changes with distance.
What to Teach Instead
Encourage students to measure how far apart the magnet and object can be while still attracting. Ask them to compare distances for different magnets and explain their findings in terms of force weakening over distance.
Assessment Ideas
After Magnet Testing Stations, provide students with a small collection of objects (e.g., paperclip, coin, plastic toy, iron nail). Ask them to sort the objects into two groups: 'Magnetic' and 'Non-Magnetic'. On the back, they should write one sentence explaining how they decided on the classification.
After Pole Identification Challenge, present students with two bar magnets. Ask: 'What do you observe when I bring these ends together? What happens when I flip one magnet? Can you explain why this happens using the terms attraction and repulsion?'
During the Magnetic Fishing Game, circulate and ask individual students: 'How are you measuring which magnet is stronger? What does it mean if a magnet can pull a paperclip from further away?'
Extensions & Scaffolding
- Challenge students to design a device that sorts magnetic from non-magnetic objects using only a magnet and household materials.
- Scaffolding: Provide labeled bins for magnetic and non-magnetic items and a visual checklist for fair test steps.
- Deeper exploration: Have students graph the pull distance of different magnets and compare results in small groups.
Key Vocabulary
| Magnet | An object that produces a magnetic field, capable of attracting or repelling certain materials. |
| Magnetic Force | An invisible push or pull exerted by a magnet on other magnets or magnetic materials without direct contact. |
| Attraction | The force that pulls two magnetic objects or poles together. |
| Repulsion | The force that pushes two magnetic objects or poles away from each other. |
| Magnetic Material | A substance that is attracted to magnets, such as iron, nickel, or cobalt. |
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.
