At the end of this unit
in terms of scientific enquiry
most pupils will: select and make effective use of secondary sources about the origins and uses of metals; identify relevant observations and describe patterns in these; suggest a workable approach to investigating the reaction of metals with acids, identifying variables to be controlled; explain results using scientific knowledge and understanding
some pupils will not have made so much progress and will: select information from secondary sources about the origins and uses of metals; describe observations and identify where there are similarities; suggest how reaction with acids might be investigated, controlling variables identified for them; relate results to scientific knowledge and understanding
some pupils will have progressed further and will:
synthesise information from secondary sources; point out where reactions do not fit the pattern expected
in terms of materials and their properties
most pupils will: identify and describe similarities in chemical reactions; identify differences in the reactivity of different metals and use these to explain some everyday uses and occurrence of metals; represent chemical reactions by word equations
some pupils will not have made so much progress and will:
describe how some metals react with water, acids and oxygen; give some uses of metals, relating these to the reactivity of the metal
some pupils will have progressed further and will: use the reactivity series to make predictions about the reactions of metals; relate the reactivity of a metal to its uses, how it occurs and when it was first extracted and used; represent some reactions by symbol equations
