Lesson: Magnets and Compasses 101
Lesson Objective
Lesson Plan
Year 8 Physics Lesson Plan |
Module title: Magnetism
Lesson title: Magnetism 101 - Basic Properties of Magnets
Time allocated: 1 week [1 single, 1 double, 1 prep]
Learning outcomes for ALL students ("MUST" and "SHOULD"): *Understanding that there are only 4 naturally occurring - and metallic - materials commonly in existence *Discovering the basic properties of magnets - that like poles repel and unlike poles attract. *To plot the magnetic field pattern around a simple bar magnet using a plotting compass. |

Experiments/Demonstrations: *Experiment 1: Magnetic or non-magnetic: need 10 items of which 4-5 should be magnetic (nickel, iron, steel, cobalt?, 1or 2p coin). Must be labelled else Al and Zn get confused etc. OR order up H.Shaw Magnet sets - just metals and all labelled A-L for them! *Experiment 2: Blocking Magnetic Fields: Clamp stand holding a magnet. Tie a paperclip to a 1m length of string, which you tie to the base of the clamp stand. The paperclip should be able to levitate about 1cm below the magnet. Offer in the space between: sheet of paper or very thin sheet of iron/steel etc. *Demo 1: Attraction or Repulsion: Need clamp stand (from Experiment 2) with paper cradles for free standing rotation of magnet hanging within. Offer a second magnet such that alike poles cause rotation away and unlike poles cause rotation towards the student. *Experiment 4: Plotting magnetic fields: Drawing around a magnet and tracking the magnetic field with a small circular plotting compass. *Demo 2: Magnetic fields around a bar magnet: 'Magnetic Field Pattern Window': transparent plastic with Fe filings trapped inside oil and bar magnet is placed on the outside (I don't think this is very good) OR plastic casings with small grid of compasses and you can connect these together in 3 planes to see the field in 3D (see Notes - Magnetic Field Demonstrator - fantastic piece of kit)).
