This resource is designed for the current OCR A-level Biology specification. It is suggested that these resources be used at the end of learning the topic on Biological Membranes where the series of different activities are designed to revise and recap the topic. This then leads to using the exam question pack which gets students recalling and applying their understanding to answer the questions. There are mark schemes for both the activity pack and the exam question pack. The mark schemes can be used for either self or peer assessment. The resources provided here will take on average an hour lesson to complete and dependent on the level of the students may take longer. Specific tasks/exam questions could then be set as a homework task to complete. It includes different activities to cover the following learning objectives: The roles of membranes within cells and at the surface of cells. The fluid mosaic model of membrane structure and the roles of its components. 3)The movement of molecules across membranes.
