Energy: Technology Exercises

This section, on the full version CD, contains technology exercises, including:

Primary production of aluminium alloys versus recycling of aluminium products.

1. Research the processes involved in mining aluminium ore and converting it into the aluminium alloys that are used to make products.

2. Research the processes involved in recycling aluminium products and converting them into high quality aluminium alloys that are used to make new products.

3. Compare the production of aluminium alloys from aluminium ore to the production of aluminium alloys from recycled aluminium products and state which process, in your opinion, uses the greater amount of energy.

4. Describe the likely consequences of each method of aluminium alloy production on the environment. 

5. Draw a flow chart of the stages involved in the aluminium recycling process. 

Energy: Design Exercises

This section, on the full version CD, contains design exercises, including:

Sailing yachts have electrical navigation instruments and lights that are run off the yacht’s battery. 

Design a method of harnessing the power of the wind to drive a small electric generator that could be used to recharge a battery.  Use notes and sketches to illustrate your designs.
