  2. Cool activity to do with your parents!! What do you do after you hold one end of the copper wire to the negative end of the battery? Set the flat head on top of the disc magnet Watch what happens to the screw Touch the other end of the disc magnet Move the positive end of the battery Who is the audience? Parents Teachers Children Adults

  3. Which if these might you expect to see under “What You Need?” A list of safety equipment Ideas for how to use your electric motor Instructions for how to check a battery A list of books about electric motors

  4. Equipment:1. Sewing needle ~1 inch (3cm?) long.2. Small bar magnet. Refrigerator magnets may work if you don't have a bar magnet.3. A small piece of cork.4. A small glass or cup of water to float the cork and needle. • How to do the experiment:1. Your compass will work better if you first run a magnet over the needle a few times, always in the same direction. This action 'magnetizes' is to some extent. Drive the needle through a piece of cork. Cork from wine bottles works well. Cut off a small circle from one end of the cork, and drive the needle through it, from one end of the circle to the other, instead of through the exact middle - be careful not to stick yourself! • 2. Float the cork + needle in your cup of water so the floating needle lies roughly parallel to the surface of the water. • 3. Place your 'compass' on a still surface and watch what happens. The needle should come to point towards the nearest magnetic pole - north or south as the case may be. • 4. If you want to experiment further, try placing a magnet near your compass and watch what happens. How close/far does can the magnet be to cause any effects? Making a Compass Fun to do with your students!! What do you do while you place your compass on a still surface? Place a magnet near your compass Drive a needle through it Cut a small circle from one end of he cork Watch what happens Who is the audience? Children Students Parents teachers
