Scheme of work

Ref	Lesson pack	Structure	Worksheet	Quiz	Lab tab
5.2.1	Background radiation A radiation detector never reads zero, even with no source in sight.	Cooperative Concept Mapping	6 Q, 12 marks	2 MCQ	tab 1
5.2.2	Alpha, beta and gamma radiation An unstable nucleus can throw out three very different things: a heavy charged chunk, a tiny fast particle, or a burst of pure energy.	Think-Pair-Share	6 Q, 15 marks	4 MCQ	tab 2
5.2.2	Deflection of radiation in fields Send the three radiations through a magnetic field and they part company.	Mix-Pair-Share	6 Q, 13 marks	4 MCQ	tab 3
5.2.3	Radioactive decay equations When a nucleus decays it does not vanish, it transforms, and the bookkeeping is exact.	Round Table	6 Q, 13 marks	3 MCQ	tab 4
5.2.4	Half-life You cannot say when one nucleus will decay, but you can say exactly how long it takes for half of a whole sample to go.	Rally Coach	6 Q, 12 marks	2 MCQ	tab 5
5.2.4	Applications of radioactivity The same radiation that can harm is, used carefully, a precise tool.	Frayer Model	6 Q, 15 marks	6 MCQ	tab 6
5.2.5	Safety with ionising radiation Ionising radiation does its damage quietly, cell by cell, with no warning you can feel.	Connect-Extend-Challenge	6 Q, 12 marks	1 MCQ	tab 7

Each pack holds the plan, worksheet and quiz for its lesson. Teach the rows in order; the lab tabs match the student lessons.
