This is a lesson for the new AQA GCSE Biology Specification, it particularly meets specification points from the 'Infection & Response' unit.

The lesson begins by pupils thinking about the type of risk-factors that increases someone's chances of developing cancer. The lesson then goes on to introduce the definition of cancer and identifies some of the parts of the body that cancer can most commonly affect.

Pupils are then given, in pairs, the definition of malignant and benign tumours, they will need to teach their peer the definition of this word for their peer to write down - not just read it and copy it from the piece of paper!

The slide will outline what happens if the cancer metastasises, there is a video demonstrating how cancer can spread from one part of the body to another.

The next activity pupils are given a grid with symbols/diagrams on, pupils will need to identify the risk-factors of cancer that these diagrams represent. Some are a little more difficult than others, I have included the names of the more difficult ones on the board but you can it more/less challenging to suit the ability of your class. Once finished pupils can self-assess their work using red pens.

For the plenary pupils will answer a past-paper question and then peer-assess their work.
