Magnetism - Magnets and Electromagnets Explained - Classroom, Distance and Blended Learning for KS3

The two packs in this resource allow the same lesson to be taught to students whether they are in a classroom or distance learning at home. It facilitates blended learning and provides equality of opportunity for vulnerable students who are unable to attend school due to Covid-19.

The classroom resource consists of an animated 45- slide PowerPoint and 15 varied and exciting printables including a foldable, cut-and-stick and progress check. The one-page flowchart lesson plan shows where choices can be made between the printables so that the teacher can select the activities to suit the exact needs of their class.

The distance learning pack consists of a 90 - slide animated PowerPoint which, not only teaches the science but also how to gain maximum benefit from distance learning. The PowerPoint has been designed to replace the teacher by providing structure, sequence, knowledge and answers. Additional 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. These can be printed off by the student or provided by school. There is also a short digital test/homework which can be returned to the teacher. A shortened photocopiable PDF of the PowerPoint is provided to circulate to those pupils without computers.

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.
