New GCSE AQA Physics lesson on 'Atoms and Radiation' written in line with new AQA Physics specification. Lesson provides a basic introduction to the unit of Nuclear Radiation, ideal for introduction and low ability groups.
Starter prompts pupils to write or draw what they know about nuclear radiation onto a post-it note, this can then be reviewed by the teacher to start a discussion on misconceptions and highlighting good knowledge. A brief background on the discovery of radiation is given in relation to Henri Becquerel and Marie Curie. A simple explanation of nuclear radiation is given with some review of the nucleus and ionising radiation. Detection of radiation is highlight with a Geiger-muller tube and counter. The three types of nuclear radiations are stated and the nature of random nuclear decay is highlighted. The lesson concludes with a fun true or false about nuclear radiation with some videos to offer further explanation where appropriate.
A summary worksheet is provided.
Lesson Objectives:
- Explain what a radioactive substance is & what makes a substance radioactive.
- Explain how radioactivity can be detected.
- Recall the different types of radiation that is emitted from a radioactive substance.
- Explain what is meant by ‘nuclear decay’.
