This detailed and engaging lesson supports students with their revision in the build up to their UNIT 2 mocks or final assessment. The wide range of tasks and activities will challenge them on their knowledge of Cells, Development, Biodiversity and Conservation (topics 3 and 4) of the Edexcel International A-level biology specification, allowing them to identify any areas which require further attention before the examinations.

Included in the range of tasks are exam-style questions and understanding checks and all answers are embedded into the PowerPoint. There are quiz rounds to maintain engagement and to encourage healthy competition, as well as guided discussion periods to provide opportunities for students to support each other.

The following content is directly covered by this revision lesson:

The mitotic cell cycle
Calculating the mitotic index
The events of meiosis which contribute to variation
The structure of cellulose
The structure and function of organelles
The meaning of the term locus
The Hardy-Weinberg principle
Evolution through natural selection
Calculating the index of diversity
The heterozygosity index
Conservation of endangered species through captive breeding programmes

Many of the tasks have been differentiated to maintain challenge whilst providing access to all.

This is an extensive lesson with many tasks so it is estimated that it will take over 3 hours of teaching time if covered in full, but teachers may choose to use sections to focus on a specific topic.
