Science / Year 7 term 3: Electromagnets / YEAR GROUP: 7
Prior learning (check earlier Key Stages) / Students will have studied magnets at Key Stage 2
Lesson number and title / LEARNING OUTCOMES – What will your learners be able to do by the end of the lesson (how will you know?). Use Bloom’s Taxonomy / Timing / Specific resources
1 / Magnetic materials / l Identify materials as either magnetic or non-magnetic
l Describe how to make a magnetic material a magnet
l Explain why materials are magnetic
l Construct a graph to display / 100 minutes / Class set of bar magnets (30), Pieces of iron rod (15), Materials for circus (Wood, iron, plastic, aluminium, copper, steel, nickel, paper), Class set worksheet 8.1.1 (consumable), Class set large nails (15), supply of paperclips,
Class set of KS3 7P(3) 1.2 and 8 sets each of KS3 7P(3) 3.3 and 3.4 cut in half.
2 / Magnetic fields / · Describe how you could find the magnetic field of a bar magnet
· Explain how the strength of a magnetic field varies
· Compare the magnetic fields of two interacting bar magnets when they are attracting and repelling each other / 100 minutes / Class set pb.9.1, Pb.9.2 (consumable), Iron filings, Acetate sheets, magnet attached to retort stand and a paperclip on string stuck to the bottom of the stand (the amazing paperclip demo!), Class set magnets (15), Class set compasses (15), Plain paper, post-it notes
Half a class set of
KS3 2.2 and 2.3
3 / Compasses / l Describe the pattern of the Earth’s magnetic field
l Explain the difference between magnetic variation and
deviation
l Apply your knowledge of magnetic fields to explain how compasses are used in navigation / 100 minutes / Two magnets hanging from thread, pieces of polystyrene, pins, bar mangets, plastic cups/small tubs. Half a class set of KS3 7P(3) 3.2 and 3.3 a full set of 3.4 and half a class set of 3.5
4 / Electromagnets(1) / l Define the term ‘solenoid’
l Describe how to make an electromagnet
l Construct a plan to investigate factors affect the strength of an electromagnet and identify the key variables in the investigation
l Predict how different factors will affect the strength if an electromagnet / 100 minutes / 15 sets practical equipment ( Power pack, half metre length of wire, 2 croc clips, 2 leads, iron core, supply of paper clips.),Half a class set of KS3 7P(3)4.2 and half a class set of KS3 7P(3)4.3. 3 copies of 4.4 with each table cut out please
5 / Electromagnets (2) / l Carry out a practical to investigate how the number of coils in a wire affects the strength of an electromagnet
l Construct a suitable graph to display your results
l Conclude your results / 100 minutes / 15 sets practical equipment ( Power pack, half metre length of wire, 2 croc clips, 2 leads, iron core, supply of paper clips.),
6. / Applications of electromagnets / l State examples of devises that use electromagnets
l Describe how a scrap metal sorter works
l Explain why it is useful to have an electromagnet rather than a permanent magnet is some situations / 100 minutes / 6 copies of each of KS3 7P3 6.2, 6.3, 6.4 and 6.5
