Magnetism - Magnets and Electromagnets Explained - Distance Learning and Homeschool for KS3

This is an action-packed distance learning or home school introduction to magnetism.

This resource has been designed so that the animated PowerPoint replaces the teacher by providing structure, sequence, knowledge and answers. The worksheets, cut-outs, foldable and progress check provide a familiar medium for students to develop and test their knowledge, continue to develop their literacy skills and use their creativity to organise their learning and assess their progress.

The simulated practical takes the student through designing an investigation, a table and drawing a graph.

What’s Covered
Magnetic materials can be made into magnets.
Iron, cobalt and nickel and their alloys are magnetic materials.
Unlike poles attract and like pole repel.
There is an invisible magnetic field around a magnet made up of field lines.
Draw the field lines around a bar magnet.
The closer together the field lines the stronger the magnetic field.
Draw the field lines around two bar magnets with like and unlike poles facing.
There are more field lines around the poles where the magnetic field is strongest.
The magnetic field strength gets less as distance from the magnet increases.
Field lines point away from the south pole and towards the north pole of a magnet.
When a magnetic material is made into a magnet, the randomly facing domains all line up to point in the same direction.
The Earth acts as though there as a south-type pole at magnetic north and a north-type pole at magnetic south.
Explain how an electric bell, a relay and a circuit breaker work.

Resources

   explaining how to use distance learning effectively;
   explaining how to use this resource;
   explaining current, voltage and resistance and the relationship between them;
   providing the answers to all the worksheets so that the students can mark and correct their work.

2. Four worksheets, and two cut-out activities, the answers to which are in the PowerPoint.

3. A foldable and cut-out activity so that students can record and organise their learning.
