Development of the model of the atom lesson with questions and answers

Development of the model of the atom GCSE Physics lesson including J.J Thomson, Ernest Rutherford, plum pudding model, nuclear model, alpha particle scattering experiment (gold foil experiment), with questions and answers throughout the lesson. The lesson objectives are as follows: Explain why the discovery of the electron led to a new model for the atom and describe this new model, explain why the new evidence from the scattering experiment led to a change in the atomic model and explain the difference between the plum pudding model of the atom and the nuclear model of the atom. The slides are fully animated and include answers to every mini plenary question and exam question. The breakdown of the slides is as follows:

Slide 1 - Title and 5-minute starter. The starter is a grid of four questions entitled ‘last week, last lesson, today’s learning and future learning’. Use this generic slide for all of your lessons by simply changing the questions and the answers each time.
Slide 2 - Lesson objectives (see above)
Slide 3 – Open question: what does an atom look like? John Dalton’s atomic model is mentioned here
Slide 4 – Introduction to J.J. Thomson and new experimental evidence may lead to an existing model being changed or replaced
Slide 5 – Explanation of the plum pudding model
Slide 6 – Mention of Hantaro Nagaoka, a Japanese scientist who disagreed with Thomson’s plum pudding model. Inclusion of Nagaoka provides an opportunity to diversify the curriculum.
Slide 7 - Mini plenary. Three questions of increasing difficulty. Answers animate onto the screen
Slide 8 – Information about Ernest Rutherford and description of gold foil experiment
Slide 9 – Explanation of Rutherford’s results
Slide 10 - Mini plenary. 4-mark exam question with answer that animates on to the screen.
Slide 11 – Small additions to the nuclear model, e.g. Niels Bohr, James Chadwick and discovery of the proton.
Slide 12 - Applied learning time (ALT). 6-mark exam question with answer.
Slide 13 - Plenary. Quick fire questions with names of random students in the class. Alternatively, you can use the No hands app random name generator
