At the end of this unit
in terms of scientific enquiry
most pupils will: obtain and present qualitative results, identifying patterns in these; work safely with acids and when burning materials; suggest how to test an idea about burning, obtaining results which can be represented as a line graph
some pupils will not have made so much progress and will: obtain and present qualitative results, describe some hazards of acids and of burning; work safely with acids and when burning materials; test an idea about burning and present results
some pupils will have progressed further and will: evaluate how well ideas about burning match the data collected
in terms of materials and their properties
most pupils will: identify that some new materials are formed during a chemical reaction and generalise that hydrogen is formed when acids react with metals, carbon dioxide when acids react with carbonates, and oxides when materials burn; describe tests for carbon dioxide and hydrogen and describe burning as a reaction with oxygen
some pupils will not have made so much progress and will: identify some products of chemical reactions and state that oxygen or air is needed for burning
some pupils will have progressed further and will: predict that carbon dioxide and water will be made when a hydrocarbon burns and use word equations to represent reactions in which materials burn
