AQA Trilogy GCSE (9-1) Biology – Chromosomes
This is a lesson which meets specification points in the NEW AQA GCSE (2016) 'Cells' SoW.

This lesson begins by watching a video about the structure of cells and where to find the genetic information, pupils will watch the video and answer questions (provided in the PowerPoint presentation.)

Pupils will then be presented with a labelled diagram of a cell, nucleus, chromosome and gene. Pupils will be required to analyse the diagram for a few minutes (you can include a stop clock on the board). The screen will then be changed, and pupils will be given a blank copy of the diagram which they will need to complete from memory - pupils can then peer-assess their work.

In the next activity, pupils are shown diagrams of a cell with a nucleus visible, DNA, a gene and a chromosome. Pupils can either create a flow chart by cutting and sticking the diagrams in order from largest to smallest and then labelling them. Alternatively, they could draw their own diagrams and label them. Pupils can then self-assess their work using red pens.

The next activity, pupils are given a series of words and definitions, they will need to match the key words up to the correct definition. Pupils then self-assess their work.

There are two option for the plenary activity, for lower ability classes pupils will be required to fill in the blanks in a paragraph describing the structure and function of genetic information and where it is found within the cell. The second plenary is a past-paper question, pupils can answer this in their books and then peer-assess using red pens.
