Thinking about actions to take: Radiations that Ionise
Teaching Guidance for 14-16
There's a good chance you could improve your teaching if you were to:
- dealing with the properties of ionising radiations before exploring their sources
- linking the behaviour of nuclear radiations to the behaviour of radiations from other sources
- exploiting the photon model to make the link between ionising and non-ionising radiations
- using the introduction of detectors as an opportunity to reinforce the process of ionising
- relating half-thickness and half-life
- comparing risks from ionising radiations to risks from other sources
Work through the Physics Narrative to find these lines of thinking worked out and then look in the Teaching Approaches for some examples of activities.
- treating ionising radiation as a completely isolated phenomenon
- getting bogged down in the different measures of ionising radiations
- not challenging
These difficulties are distilled from: the research findings; the practice of well-connected teachers with expertise; issues intrinsic to representing the physics well.
