Introduction to Magnetic MaterialsActivities & Teaching Strategies
Hands-on testing lets students feel the pull of magnetism directly, turning abstract forces into something they can see and discuss. Active sorting and movement games keep Year 3 learners engaged while they build lasting understanding through evidence, not just listening.
Learning Objectives
- 1Classify a range of common objects as either magnetic or non-magnetic based on experimental testing.
- 2Identify materials that are attracted to magnets, listing at least three examples.
- 3Analyze the effect of a magnet on an object at a distance, describing the interaction without physical contact.
- 4Predict whether an unfamiliar material will be attracted to a magnet, justifying the prediction with reasoning about its likely composition.

Sorting Station: Magnetic Hunt
Prepare trays with 15 mixed objects like paperclips, coins, spoons, erasers, and keys. Pairs test each item with a magnet, sort into 'attracts' or 'does not attract' piles, and label with reasons. Groups share one surprise find with the class.
Prepare & details
Differentiate between magnetic and non-magnetic materials.
Facilitation Tip: During the Magnetic Hunt, circulate with a checklist so every pair gets feedback on their sorting choices.
Setup: Tables/desks arranged in 4-6 distinct stations around room
Materials: Station instruction cards, Different materials per station, Rotation timer
Prediction Challenge: Mystery Box
Fill boxes with unseen objects. Small groups predict if each will attract a magnet, test one by one, and vote on results before revealing. Discuss why predictions matched or failed, updating a class prediction chart.
Prepare & details
Analyze how a magnet can move an object without touching it.
Facilitation Tip: In the Mystery Box, listen for predictions that name specific metals like steel or aluminium before testing.
Setup: Tables/desks arranged in 4-6 distinct stations around room
Materials: Station instruction cards, Different materials per station, Rotation timer
Non-Contact Relay: Magnet Push
Place iron filings or paperclips in a line on tables. Small groups use magnets to move objects across without touching, racing to the end. Note distance effects and switch roles for fairness.
Prepare & details
Predict which new materials might be attracted to a magnet.
Facilitation Tip: During the Non-Contact Relay, mark starting lines with masking tape to standardise distance trials.
Setup: Tables/desks arranged in 4-6 distinct stations around room
Materials: Station instruction cards, Different materials per station, Rotation timer
Classroom Magnet Scavenger: Object Audit
Whole class hunts for magnetic items around the room, tests them, and lists on a shared board. Categorise by material type and vote on most surprising magnetic object.

Teaching This Topic
Teachers pair prediction with immediate testing so misconceptions surface and are corrected on the spot. Avoid over-explaining; let the objects and magnets do the talking. Research shows that short, focused activities with clear outcomes build stronger science reasoning than longer, open-ended tasks at this age.
What to Expect
By the end of the lesson, every child can confidently test objects, explain why some items move and others do not, and describe the force without contact. Clear recording and peer talk show they can apply ideas beyond the magnet tray.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Sorting Station: Magnetic Hunt, watch for students grouping all metals together.
What to Teach Instead
Prompt them to test a copper coin and an aluminium strip alongside a steel screw, then ask the group to re-sort based on evidence from their trays.
Common MisconceptionDuring Non-Contact Relay: Magnet Push, watch for students moving the magnet until it touches the object.
What to Teach Instead
Hold up a ruler and demonstrate the gap, then challenge pairs to measure the largest gap that still moves the ring before they start the race.
Common MisconceptionDuring Sorting Station: Magnetic Hunt, watch for explanations that mention glue or sticky tape.
What to Teach Instead
Ask students to compare how easily a magnet releases a paperclip versus how sticky tape holds a button, prompting discussion about different kinds of forces.
Assessment Ideas
After Sorting Station: Magnetic Hunt, provide a small collection of objects and ask students to test each with a bar magnet and record their findings in a simple table with columns for 'Object' and 'Magnetic/Non-magnetic'. Check their tables for accuracy.
After Mystery Box, give each student a card with a picture of a new object and ask them to write one sentence explaining if it will be attracted to a magnet and why, based on what they learned about magnetic materials.
During Classroom Magnet Scavenger: Object Audit, hold up a magnet and a wooden block at a distance and ask, 'How can the magnet affect the block, even though they are not touching?' Listen for explanations that describe an invisible force or pull.
Extensions & Scaffolding
- Challenge: Provide a set of plated cutlery and ask students to predict which will attract based on visible coatings and core materials.
- Scaffolding: Give a picture key of magnetic metals to place beside each object for students who need visual reminders.
- Deeper exploration: Introduce a second bar magnet and ask how turning it changes the force, introducing polarity in simple terms.
Key Vocabulary
| Magnet | An object that produces a magnetic field, causing a force that attracts or repels certain other objects. |
| Magnetic Material | A substance that is attracted to a magnet, typically containing iron, nickel, or cobalt. |
| Non-magnetic Material | A substance that is not attracted to a magnet, such as wood, plastic, or aluminum. |
| Attract | To pull something towards a magnet, usually because the object is made of a magnetic material. |
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.
More in Forces and Magnets: The Invisible Pull
Identifying Pushes and Pulls
Students will identify and describe different types of forces as pushes or pulls acting on objects, observing their effects on motion.
2 methodologies
Observing Movement on Surfaces
Students will investigate how objects move differently on various surfaces, observing how some surfaces make things slow down or stop more easily.
2 methodologies
Investigating Friction
Students will design simple experiments to measure and compare the amount of friction on various surfaces.
2 methodologies
Magnetic Poles: Attract or Repel
Students will investigate the two poles of a magnet and observe the forces of attraction and repulsion.
2 methodologies
Exploring Magnetic Strength
Students will explore the invisible magnetic field around magnets using iron filings and test the strength of different magnets by observing how many paperclips they can hold.
