Science at key stage 3 (Year 9)

Unit 9H: Using chemistry
Section 11: Reviewing work

Objectives

Children should learn:

to recognise the variety in chemical reactions
to make some generalisations about reactions

Activities		Outcomes
		Children:
Provide pupils with word equations and/or symbol equations, general equations and descriptions of reactions, eg neutralisation, combination with oxygen, displacement, and ask them to group together similar reactions. Include some that don't fit into any category. Discuss these and the classifications with pupils and agree with them a short list of key points about reactions, eg new materials are made atoms combine in different arrangements evidence for reaction includes ... mass is conserved because atoms link together in different ways chemicals are an energy resource because energy is often released when reactions occur		match word equations to descriptions of reactions and/or symbol equations group together some reactions of a similar type identify key points about reactions
