This unit uses ideas developed in the key stage 2 programme of study. It builds on ideas introduced in
unit 5C 'Gases around us' and
unit 6D 'Reversible and irreversible changes' in the key stage 2 scheme of work.
This unit relates closely to unit 7E 'Acids and alkalis' and these can be used together as an introductory unit in year 7, in which pupils use equipment and techniques they may not have encountered in key stage 2.
An approach to teaching about energy is included in the
Teacher's guide and in the 'About the unit' section of unit 7I 'Energy resources'.
Unit 9E 'Reactions of metals and metal compounds' and unit 9F 'Patterns of reactivity' include further work on the reactions of acids and on burning as a chemical change. Unit 9H 'Using chemistry' includes work on the conservation of mass in chemical reactions, including burning.
