Reduction Reaction and Electrolysis *BIG PRACTICAL* Reactivity Series

Resources developed as part of a *BIG PRACTICAL*. These are designed to practice a skill - usually using a preliminary investigation - then a full investigation write up. These are tailored toward the way the new GCSE (2016 on wards) is designed to test practical skills as well as context.

First lesson
Resources: Reduction-Reactions (+ppt)
Practical: Pupils complete a practical looking at the reduction of iron in iron oxide using carbon on a match.
Activities order: Starter looking at the reactivity series and the order of metals. First section looks at those found in their natural state and not in compounds. Then move on to look at those above hydrogen and below carbon using practical.

Second
Resources: Electrolysis (+ppt)
Practical: Electrolysis of copper sulphate solution - simplistic
Activities order: Introduction the meaning of the term 'lysis' and linking it to electrolysis. How ores are processed to get compounds ready for electrolysis. Electrolysis of sodium chloride and aluminium oxide as examples.
