Scheme of work

Ref	Lesson pack	Structure	Worksheet	Quiz	Lab tab
12.1	Experimental design and apparatus Every practical question starts with the same choices: what to measure, which apparatus to use and how precise it needs to be.	Frayer Model	6 Q, 15 marks	8 MCQ	none
12.2	Acid-base titrations A titration finds exactly how much acid neutralises a measured volume of alkali.	Numbered Heads Together	6 Q, 16 marks	8 MCQ	tab 6
12.3	Chromatography A spot of ink on paper, a little solvent, and ten minutes later the mixture has spread into its separate components.	Anticipation / Reaction Guide	6 Q, 13 marks	8 MCQ	none
12.4	Separation and purification Salt from sea water, pure water from ink, ethanol from a fermented mixture: each separation uses a difference in property, whether solubility, particle size or boiling point.	Cooperative Concept Mapping	6 Q, 14 marks	8 MCQ	none
12.5	Tests for anions and cations A white powder could be almost anything.	Quiz-Quiz-Trade	6 Q, 16 marks	8 MCQ	tab 5
12.5	Tests for gases Colourless gases look identical, but each one reacts in a way that gives it away: a squeaky pop, a splint bursting into flame, limewater turning milky.	Mix-Pair-Share	6 Q, 13 marks	8 MCQ	tab 1
