Science at key stage 3 (Year 7)

Unit 7F: Simple chemical reactions
Section 3: b. How do acids react with metals?

Objectives

Children should learn:

to record relevant observations
to identify and describe patterns in qualitative data
to identify results which do not appear to fit the pattern

Activities		Outcomes
		Children:
Ask pupils to investigate what happens when a range of acids is added to a range of metals and to record and make generalisations from their results. Bring together pupils' results and establish that in most cases a new material, hydrogen, is made, showing that there was a chemical reaction between the acid and the metal.		use a table to present observations in a way which enables patterns to be seen identify metal(s), eg copper, which do not react with acids to produce hydrogen conclude that when hydrogen was made a chemical reaction had taken place

Points to note

At this stage, it is sufficient for many pupils to identify that acids react with many metals to produce hydrogen. Some teachers may wish to take this further, either by considering what other products are obtained or by considering patterns in reactivity. This is more fully covered in unit 9F 'Patterns of reactivity'.
