Practical investigation: Different types of permanent magnets – bar and horseshoe. Learners must use their knowledge of structures and the drawing skills developed in 8 earlier tasks, together with their new knowledge of magnetism, electric circuits and electromagnets as well as their new knowledge of cranks and pulleys to design and make a crane using an electromagnet to sort metals in a scrap-yard. Case study: Examine pictures of cranes in order to get ideas to be used in the learner’s own designs.

Investigation skills Case study: recycling scrap metals. Honest gleaners who collect scrap metal and deliver it to scrap metal dealers perform a valuable service to society. This good work is tainted by the criminal acts of thieves who steal copper telephone wire and steel 11 manhole covers. Simple electric circuits. Demonstrate a simple electric circuit with an energy source (cell), switch, conductor and a light bulb or buzzer. Sketch the circuit showing how to use component symbols.

Make a simple electromagnet made by winding insulated copper wire around an iron nail. When an electric 12 current flows in the wire coil (solenoid) a magnetic field is created and this is amplified by the iron core. Switching the current off causes the magnetic field to fade away. (Note: electromagnetism is a key to a wide range of technologies making up our modern world.) •Sketch two possible designs for a suitable crane using single VP perspective. 13 •Draw a circuit diagram for the electromagnet (with a light to show when it is on). Revision: Revise the 3D oblique drawing technique; line types; scale; dimensions. drawing: Each learner uses the Oblique technique to draw an idea for the crane 14 chosen from the two ideas sketched the previous week. The idea should be drawn on squared paper (quadrant) using pencil and ruler. Flow chart: Each learner works out a flow chart detailing the sequence of manufacture of the crane with its electromagnet.

Each team presents the design sketches, working drawings and functioning model to the class. They demonstrate how strong their electromagnet is and show that it releases the load when switched off. Each learner explains the role s/he played and shares the role of spokesperson. They explain the principles involved with the 15 magnetic sorting and how their electromagnet could be made stronger. They comment on the value of recycling and explain how sorting the metals into types, improves their scrap value. They enhance their presentation using posters giving an artist’s impression of their completed crane and electromagnet in use. GRADE 7 REVISED TERM 4 CONTENT Learners investigate emergency situations that can lead to refugees: • Find out what situations commonly result in people becoming refugees. 16 • Find out what initial problems are typically faced by refugees. • What mix of people will usually be present? • What are their needs for shelter?

Learners design and make a simple emergency shelter for disaster victims. The shelter must be sturdy, waterproof, easy to erect and able to house a family of six for a month. Learners must be aware of the importance of health and safety issues. Investigate: Learners investigate materials and building techniques used by indigenous people for constructing housing in rural South Africa. Materials used in such construction is typically readily available, appropriate and environmentally friendly. 20 Investigate: Learners compare materials and building techniques used by people setting up informal settlements.
