Content
Activity: to demonstrate the magnetism in the poles of a magnet [lo 1.2]
For the educator: Place a thick line of iron filings on a clean sheet of paper. Carefully insert a bar magnet into a test tube. Draw the test tube through the line of iron filings.

- The ends of the bar magnet are known as the poles of the magnet. The red end is the north pole (north-seeking pole) and the blue end is the south pole (south-seeking pole).
3. forces between magnets
When magnets are near one another, forces are generated between them. The following experiment will make it possible to find out what these forces are.
Assessment
Learning Outcome 1: The learner will be able to act confidently on curiosity about natural phenomena, and to investigate relationships and solve problems in scientific, technological and environmental contexts.
Assessment Standard 1.2: We know this when the learner conducts investigations and collects data: organises and uses apparatus/equipment or sources to gain and record information;
