- %CO:A,12,72%Attainment target 7: Making new materials
-
- Pupils should develop their knowledge and understanding of the
- processes of changing materials by chemical reaction and the way this
- is used in the manufacture of new materials.
-
- Level 4 * know that when a chemical reaction occurs, new materials are
- formed.
-
- * know that an important feature of manufacture is the
- conversion of raw materials, by chemical reactions, into
- useful products.
-
- Level 5 * know that air, water, rocks, living things and fossil fuels
- are all sources of raw materials for use in manufacture.
-
- * understand the application of biochemical processes in
- manufacture, for example, in fermentation.
-
- * understand the processes of combustion and rspiration in
- which fuels and oxygen combine to form oxides.
-
- Level 6 * understand the importance of reactions between acids and
- alkalis producing salts.
-
- * be able to give a simple explanation of electrolysis.
-
- * know that most chemical reactions transfer energy to the
- surroundings.
-
- Level 7 * understand the qualitative effect of temperature,
- concentration, particle size and catalysis on the rate of
- chemical reactions.
-
- * be able to relate important oxidation and reduction
- reactions to manufacturing processes and everyday effects,
- for example food oxidation.
-
- * be able to give an account of thermal and electrolytic
- decompositions in some important manufacturing processes.
-
- * understand the economic implications and the causes of
- rusting and the ways of preventing the process.
-
- Level 8 * be able to recognise quantitative relationships in the major
- factors affecting rates of chemical reacton, and that a
- practical solution may require a compromise between
- competing priorities, as shown by important manufacturing
- processes and everyday biochemical change.
-
- * be able to explain precipitation in terms of the interaction
- of ions and relate this to processes of purifaction.
-
- * be able to explain how chemicals are made from oil in terms
- of breaking up and joining molecules.
-
- * be able to rcognise examples of addition and condensation
- polymerisation, and relate them to important commercial
- polymers, their manufacture and the economic factors
- involved.
-
- Level 10 * know that the energy transferred in a chemical reaction is
- associated with the breaking and reforming of chemical
- bonds.
-
- * be able to predict the products of simple electrolytic
- reactions.
-
- * know that the rock cycle is driven by solar energy and the
- Earth's internal heat, and understand that during this
- process certain ores are concentrated, and that other raw
- materials are produced.
