This is a lesson I used myself to teach the Alpha beta and gamma concept of the Nuclear physics Unit - A level Physics, AQA specification.
Learning objective: To investigate the properties and uses of alpha, beta, and gamma radiation, explain experimental observations including Rutherford scattering and the inverse square law, and evaluate safe handling and measurement techniques using Geiger-Muller tubes.
By the end of the lesson learners should be able to:
Success criteria:
SC1: Describe the differences in ionisation, penetration, and deflection between alpha, beta, and gamma radiation and how these affect their practical uses.
SC2: Explain how Rutherford’s scattering experiment provided evidence for the nuclear model of the atom.
SC3: Apply the inverse square law to gamma radiation and evaluate how systematic errors affect measurements using a Geiger-Muller tube.
