-
- Pupils should develop their knowledge and understanding of the nature
- of energy, its transfer and control.
-
- Pupils should develop their knowledge and understanding of the range of
- energy sources and the issues involved in their exploitation.
-
- Level 1 * understand that they need food to be active.
-
- * be able to describe, by talking or other appropriate means,
- how food is necessary for life.
-
- Level 2 * understand the meaning of 'hot' and 'cold' relative to the
- temperature of their own bodies.
-
- * be able to describe how a toy with a simple mechanism which
- moves and stores energy works.
-
- Level 3 * understands in qualitative terms, that models and machines
- need a source of energy in order to work.
-
- * know that temperature is a measure of how hot (or cold)
- things are.
-
- * be able to use simple power sources (electric motors, rubber
- bands) and devices which transfer energy (gears, belts,
- levers).
-
- Level 4 * understand that energy is essential to every aspect of human
- life and activity.
-
- * know that there is a range of fuels which can be used to
- provide energy.
-
- * understand that energy can be stored, and transferred to and
- from moving things.
-
- * be able to measure temperature using a thermometer.
-
- * be able to give an account of changes that occur when
- familiar substances are heated and cooled.
-
- Level 5 * understand the need for fuel economy and efficiency.
-
- * understand the idea of global energy resources and
- appreciate that these resources are limited.
-
- Level 6 * be able to recognise different types of energy source and
- follow some processes of energy transfer in terms of the
- principle of conservation of energy.
-
- * understand that energy is conserved, but becomes spread
- around and so is less useful.
-
- * be able to explain the distinctive features which make
- machines, such as pulleys and levers, useful in everyday
- life.
-
-
- * understands that the Sun is ultimately the major energy
- resource for the Earth.
-
- Level 7 * understand energy transfer by conduction, convection and
- radiation in solids, liquids and gases and the methods of
- controlling these transfers, particularly of insulation in
- domestic and everyday purposes.
-
- * know that efficiency is a measure of how much energy is
- transferred in an intended way.
-
- * be able to evaluate methods used to reduce energy
- consumption in the home.
-
- Level 8 * understand that the ultimate result of energy transfers is
- to change the temperature of the surroundings and that
- useful energy is dissipated.
-
- * understand that the use of any energy resources involves
- both economic and environmental costs, and that such costs
- may differ in nature and magnitude, depending on the energy
- source involved.
-
- * be able to describe in outline how energy is gemerated in
- power stations from different energy sources, including
- fossil fuels, nuclear fuels, and renewable energy sources.
-
- Level 9 * be able to use the relationship between force, distance,
- work, energy and time, to describe, explain and compare the
- functioning of everyday devices.
-
- Level 10 * be able to demonstrate the application of the principle of
- conservation of energy, and to explain energy transfers in
- terms of this principle.
-
- * be able to evaluate the various costs and benefits of
- different energy sources and appreciate that society needs
- to take these into account before making appropriate
- decisions on policy.
