🧪 The Magnet Test
Objective: Which materials are attracted to a magnet?
🔮 Step 1 — Predict first!
Your prediction
Which objects do you predict the magnet will pick up?
🧰 Materials
📋 Instructions
2. Test each object with the magnet.
3. Sort the objects into 'attracted' and 'not attracted'.
⚙️ The variables
🔧 What we change
The material each object is made of
📏 What we measure
Whether the magnet attracts it
⚖️ What stays the same
The same magnet each time
📊 Step 2 — Collect your data

🔍 Step 3 — Prediction vs observation
💡 The science behind it
Magnets attract only certain metals, mainly iron and steel. The paper clip and the can contain iron or steel, but the coin (often nickel-plated steel in Singapore!) may surprise you, while plastic and wood are never attracted.
🏁 Conclusion
Test your predictions against the results. Sorting objects by their properties is how scientists classify!
🚀 Extension challenge
Try different coins. In Singapore, some coins are magnetic and some are not — why do you think that is?
🧑🏫 Teacher notes
Keep small magnets away from very young children and electronic devices.
