To know the properties of magnets. Investigation 1. Investigating magnetic materials 2. Investigating magnets through materials 3. Investigating poles 4. Investigating magnetic field Observations What I found out To know the properties of magnets. 1. Investigating magnetic materials • Go around the classroom, what materials are magnetic? • Try the materials in the cup, which are magnetic? To know the properties of magnets. 2. Investigating magnets through materials • Do the magnets still work through paper? • What about other materials? • What happens to a paper clip when you put it on a magnet? • Why? To know the properties of magnets. 3. Investigating poles Which poles attract? Which poles repel? To know the properties of magnets. 4. Investigating magnetic field • What does a magnetic field look like? • Prove it! • Use a compass to plot the magnetic field of a magnet To know the properties of magnets. To know the properties of magnets. To know the properties of magnets. Never lose your loose change again. Who needs a piggy bank when you’ve got a magnet? Magnetic Pennies Grab this stuff… Flash cash! Use the magnet to fish for pennies. Try to get a penny to spin really fast. Get a penny to roll uphill. Impress your mates with amazing penny sculptures. Use the magnets to find out in what year they started adding steel to the pennies To know the properties of magnets. Loadstone is a magnetic rock. What do you think this means? To know the properties of magnets. Loadstone refers to naturally occurring pieces of intensely magnetic magnetite that were used for magnetizing compasses. Iron, steel and ordinary magnetite are attracted to a magnetic field, including the Earth’s magnetic field. Only magnetite with a particular crystalline structure, lodestone, has the coercivity to act as a permanent magnet and attract and magnetize iron. To know the properties of magnets.
