Module 4.2.1: Biodiversity (OCR A-level Biology A)

The biodiversity topic may not be every students’ favourite, but questions relating to this module 4 topic are very common in the OCR terminal exams, meaning it can be an area where a lot of marks are unfortunately lost. With this in mind, hours of research and planning has gone into each of the 6 lessons that are included in this bundle to ensure that the slides and accompanying worksheets contain interesting and relevant biological examples that will catch the attention of the students and ultimately increase the likelihood of the retention of the detailed A-level content. There are also regular understanding checks in the form of exam-style questions with accompanying mark schemes to allow the students to assess their progress.

The following specification points in module 4.2.1 of the OCR A-level Biology A specification are covered in this bundle:

• How biodiversity may be considered at different levels
• Random sampling and non-random sampling (opportunistic, stratified, systematic)
• How to measure species richness and species evenness
• The use and interpretation of Simpson’s Index of Diversity
• How genetic biodiversity may be assessed, including calculations
• The ecological, economic and aesthetic reasons for maintaining biodiversity
• In situ and ex situ methods of maintaining biodiversity
• International and local conservation agreements made to protects species and habitats

The “reasons for maintaining biodiversity” lesson has been uploaded for free so if you download this, you will be able to recognise the quality of lesson that can be found in this bundle
