Magnets and MagnetismActivities & Teaching Strategies
Active learning works because magnetism is an invisible force, so students must physically interact with materials to build accurate mental models. Testing and mapping activities make abstract concepts tangible, helping learners connect classroom observations to real-world uses like door catches or speakers.
Learning Objectives
- 1Classify a variety of common objects as either magnetic or non-magnetic based on empirical testing.
- 2Explain the interaction between magnetic poles, predicting whether they will attract or repel.
- 3Design and construct a simple device, such as a crane or a sorting tool, that utilizes magnetic forces to perform a task.
- 4Compare the magnetic properties of different materials, identifying which ones are attracted to a magnet.

Sorting Station: Magnetic Materials Hunt
Prepare trays with 10-15 objects like coins, paperclips, wooden blocks, and foil. Students test each item with bar magnets and sort into 'magnetic' or 'non-magnetic' piles. Groups share one surprising find with the class.
Prepare & details
Differentiate between magnetic and non-magnetic materials.
Facilitation Tip: During the Sorting Station, provide a mix of metal and non-metal items with similar sizes to prevent students from guessing by weight or size alone.
Setup: Varies; may include outdoor space, lab, or community setting
Materials: Experience setup materials, Reflection journal with prompts, Observation worksheet, Connection-to-content framework
Pole Pairs: Attract or Repel?
Label magnet poles with N and S markers. Pairs test all combinations on a chart, predicting outcomes first then observing. Discuss why unlike poles stick together.
Prepare & details
Explain how magnetic poles interact and create magnetic fields.
Facilitation Tip: Before Pole Pairs, have students predict outcomes on scrap paper to encourage critical thinking before they test.
Setup: Varies; may include outdoor space, lab, or community setting
Materials: Experience setup materials, Reflection journal with prompts, Observation worksheet, Connection-to-content framework
Field Mapper: Iron Filings Reveal
Place a magnet under white paper, sprinkle iron filings, and tap gently to show patterns. Students draw the field lines and compare bar versus ring magnets. Rotate magnets to see changes.
Prepare & details
Design a simple device that utilizes magnetic forces.
Facilitation Tip: During Field Mapper, remind students to sprinkle filings gently to avoid clumping that obscures the field lines.
Setup: Varies; may include outdoor space, lab, or community setting
Materials: Experience setup materials, Reflection journal with prompts, Observation worksheet, Connection-to-content framework
Design Lab: Magnetic Crane Challenge
Provide string, magnets, sticks, and mixed metal/plastic scraps. Groups build a crane to lift only magnetic items into a bin. Test, refine, and demo best designs.
Prepare & details
Differentiate between magnetic and non-magnetic materials.
Facilitation Tip: In Design Lab, circulate with questions like 'How does the magnet’s strength affect your crane’s lift?' to guide problem-solving.
Setup: Varies; may include outdoor space, lab, or community setting
Materials: Experience setup materials, Reflection journal with prompts, Observation worksheet, Connection-to-content framework
Teaching This Topic
Teaching magnetism effectively starts with hands-on sorting to confront misconceptions early, then moves to structured exploration of poles and fields. Avoid rushing to definitions; let students observe, discuss, and refine ideas through repeated testing. Research shows that prediction-observation cycles deepen understanding more than demonstrations alone. Use small-group work to build confidence, as peer discussion helps students articulate their reasoning.
What to Expect
Successful learning looks like students confidently sorting objects by magnetic properties, predicting pole interactions, mapping fields with filings, and applying these ideas in a design challenge. Clear evidence of understanding includes justifying choices with tests and adjusting predictions based on observations.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Sorting Station, watch for students assuming all metals are magnetic.
What to Teach Instead
During Sorting Station, redirect by adding aluminum foil or copper wire to the collection and ask students to test each item, prompting them to notice that only some metals respond.
Common MisconceptionDuring Pole Pairs, watch for students thinking magnets only attract.
What to Teach Instead
During Pole Pairs, have students predict outcomes before testing and record results on a chart, highlighting that like poles repel while opposite poles attract.
Common MisconceptionDuring Field Mapper, watch for students drawing straight lines from poles to represent fields.
What to Teach Instead
During Field Mapper, have students trace the curved patterns of filings with their fingers before drawing, ensuring their models reflect the actual shape of the field.
Assessment Ideas
After Sorting Station, provide students with a small collection of objects (e.g., paperclip, eraser, coin, key, plastic block). Ask them to sort the objects into two piles: 'Magnetic' and 'Non-Magnetic'. On the back of their paper, they should write one sentence explaining how they decided which pile each object belonged in.
During Pole Pairs, hold up two magnets with different poles facing each other and ask students to give a thumbs up if the magnets will attract and a thumbs down if they will repel. Repeat with various pole combinations to check understanding of attraction and repulsion.
After Design Lab, present students with a scenario: 'Imagine you lost a small metal screw in a pile of sand. How could you use a magnet to help find it?' Facilitate a class discussion where students explain the steps they would take and why a magnet would be effective.
Extensions & Scaffolding
- Challenge: Ask students to invent a magnetic device to solve a problem at home, like picking up small nails without touching them.
- Scaffolding: Provide labeled trays for Sorting Station with pictures of metals to guide testing for students who need structure.
- Deeper exploration: Have students research how MRI machines use magnetic fields to create images of the body, then present findings to the class.
Key Vocabulary
| Magnet | An object that produces a magnetic field, capable of attracting or repelling certain materials. |
| Magnetic Field | The area around a magnet where its magnetic force can be detected. It is often visualized with lines showing the direction of the force. |
| Pole | The two ends of a magnet, typically labeled North and South, where the magnetic force is strongest. |
| Attract | To pull towards something. Opposite magnetic poles (North and South) attract each other. |
| Repel | To push away from something. Like magnetic poles (North and North, or South and South) repel each other. |
| Magnetic Material | A substance that is attracted to magnets, such as iron, nickel, and cobalt. |
Suggested Methodologies
