Literacy – Activity 1 Magnets (Literacy)
Think, Pair, Share – Students come up with a list of 5 uses for magnets Video iMac 2011 Repair – Show 30 seconds of this to show how the screen is attached by magnets! http://www.youtube.com/watch?v=ClkP-QwIOAQ Big Neodymium Magnets Destroying Stuff!!!
MAIN ACTIVITIES AND SUGGESTED RESOURCES Activity 1 – What are you attracted to? Students use bar magnets to test a variety of items to see it the magnet is attracted to the material. CHECKPOINT – Animation – Is it Magnetic Activity 2 – Attraction and Repulsion. Students use bar magnets to show what happens when they are places N-N, N-S and S-S. CHECKPOINT – Animation – Find the Magnet
DIFFERENTIATION FOR EXTENSION/GIFTED AND TALENTED Extension – Model with class how magnets are made up of iron atoms. Each student stands up and puts out their arms to show a north pole and south pole which are all pointing in random direction. How do these atoms line up when they are placed in a magnetic field. Demo – making a magnetic using a solenoid.
Activity 3 – BBC Active Video Scrap Metal Thefts. Why do people steal metal? How can metal be sorted and recycled.? PRACTICAL Activity 2 – Sorting Metals
SPECIFICATION LINKS Tech note: Activity 1 A bar magnet and a collection of items will be required Activity 2- two bar magnets per group Activity 3- Practical to sort metals using a strong magnet, ball bearings and glass marbles and ramp.

ELECTROMAGNETS
Unit/Topic: Magnetism
LEARNING OBJECTIVES (LEVEL/GRADE) Recall what a bar magnet is (L3) Describe how to make a magnet using the stroking method (L4) Suggest what an electromagnet is (L5) Explain some applications of electromagnets (6) Explain why heating a magnet can remove its magnetism (L7)

FLIPCHART In pairs list as many things that you know about the image on the board. Class brainstorm
MAIN ACTIVITIES AND SUGGESTED RESOURCES Activity 1 – What is a magnet? 8Jc Students are introduced to flip 2 which asks students to consider the relationship between domain and magnetism. In pairs student write down a statement to describe the relationship they interpret. A brief class discussion and board annotation to help support this. Pupils will make magnet out of nails using the stroking method. Activity 2 - Following a brief demonstration of how to set up a power pack, students practically carry out the tasks in activity 1 and answer questions. http://www.nuffieldfoundation.org/practical-physics/making-permanent-magnet Activity 3 - Students are presented with an investigative question. How would you make a stronger electromagnet? Ideas are brainstormed, and they are to assess their own basic electromagnet from activity 1 and consider variables to manipulate. The basis of an investigation is to be formed. Activity 4 - Students are presented with questions for group and class discussion. Powerpoint embedded in flip. Tech notes: Activity 1 – What is a magnet? 8Jc
SUGGESTED PLENARIES Option of 3 embedded in final flip. All can also be used in combination. Floating trains 8Jc Cloze activity student copy

ELECTROMAGNETS INVESTIGATION 1
Unit/Topic: Magnetism
LEARNING OBJECTIVES (LEVEL/GRADE) Students are to focus on a particular strand of an investigation. In this case the focus is largely high quality planning and recording results in a table and graph Developing a risk assessment should also be included. The investigation is to be taught over two lessons.

FINDING YOUR WAY
Unit/Topic: Magnetism
LEARNING OBJECTIVES (LEVEL/GRADE) Recall that a magnetic field is the space around a magnet where it has an effect (L3) Use iron filings to show the shape of the magnetic field of a bar magnet(L4) Use a compass to plot the shape of magnetic fields (L5) Explain that the Earth has a magnetic field which is why compass needles point north. (L6) Explain that the Earth’s north magnetic pole acts like the south pole of a bar magnet, and is not at the geographic North Pole (L7)
