Unit 1 This scheme of work suggests possible teaching and learning activities for each section of the specification. There are far more activities suggested than it would be possible to teach. It is intended that teachers should select activities appropriate to their candidates and the curriculum time available. The first two columns summarise the specification references‚ whilst the Learning Outcomes indicate what most candidates should be able to achieve after the work is completed. The Resources

SOLAR ENERGY Solar Energy refers to energy provided by the Sun’s heat. Solar energy technologies like solar panels utilize the direct sunlight for heating and other purposes. The most common feature of the solar energy technologies is that‚ unlike other energy sources‚ it is inexhaustible. The most common application of solar energy is heating‚ cooling and electricity generation for applications like lighting. In South Africa‚ Solar energy is viable as most of the country has areas with very

purpose is to cook frozen foods more effectively. The defroster works by heating the food on the outside first‚ rather than heating it altogether as a whole‚ so as to allow the outside to assist in heating the inside of the food. In comparison to a conventional oven or rotisserie‚ the microwave oven has several advantages: First‚ it uses electromagnetic waves to cook food evenly‚ whereas a conventional oven starts heating from the outside toward the inside. This allows for greater cooking speed

means of a power transmission system and a special generator. Once the electricity is generated‚ the equipped shoe can use the electrical power for rehabilitation purpose such as thermal and cold therapy. Two effective‚ automatically controlled heating and cooling instruments embedded in the shoe ’s sole maintain proper temperature and humidity within the normal or user selected range. In addition an alternative cooling system which is less expensive but effective has been proposed. Another

It also runs air conditioners‚ heats water‚ cooks food‚ dries laundry‚ and in some cases is used for space heating. Natural gas‚ propane‚ and oil are mostly burned to provide space heating and hot water; and secondary uses for these gases include cooking‚ clothes drying‚ and fireplace fuel.
