Task 11

Materials and tools for a working group:

magnet, gauge (eg ruler), metal paper clip

The teacher points out that the pupils have discovered that the magnets are acting through obstacles, but they have probably not yet determined whether the obstacle weakens the effectof the magnet on objects. This sets another research task. The teacher guides the pupil to the design of a procedure to see if the object is attracted otherwise (weaker, more distant) than the obstacle. The teacher guides the pupils to use all the information and experience they have worked on in the past. Upon completion of the proposals, it will provide pupils with the tools and pupils will implement their design and record the results of the examination.
