At the end of this unit
in terms of scientific enquiry
most pupils will: make predictions about the behaviour of magnets and magnetic materials and draw conclusions from patterns in evidence; identify factors affecting the strength of electromagnets, make sufficient observations in an investigation of electromagnets to draw conclusions
some pupils will not have made so much progress and will: suggest how to carry out a test to distinguish between magnets and magnetic materials; make changes to vary the strength of an electromagnet
some pupils will have progressed further and will: use a model of the magnetic field to explain phenomena
in terms of physical processes
most pupils will: distinguish between magnetic and non-magnetic materials; describe magnetic shielding; make a permanent magnet and an electromagnet; describe how the Earth's magnetic field can be used for navigation; describe the shape and direction of a magnetic field; give examples of the use of magnets and electromagnets
some pupils will not have made so much progress and will: identify steel, iron and iron oxide as magnetic materials; make a magnet and electromagnet; describe the use of an electromagnet in sorting metals
some pupils will have progressed further and will: explain how magnetic materials can be magnetised using a simple particle/domain model; identify similarities in the magnetic fields of a bar magnet, the Earth and a straight coil; describe the shape of the field around a straight current-carrying conductor
