A complete revision lesson covering the digestion section of AQA module B2- organisation. It also covers the two RPAs (enzymes and food tests) that occur in this topic. The lesson opens with the food tests RPA followed by looking at the components of a balanced diet along with the role of each nutrient in the body. The lesson then moves to look at the digestive system, its components and their individual role. It then looks at the stomach as an example of an organ with its tissues and their functions. The lesson the moves onto enzyme action and the enzymes of the human digestive system. It then covers the enzymes RPA before finishing with a series of exam questions. Includes retrieval type activities All answers are provided and no printing is required Update 11/05/22- sudan III test for fats added Update 08/05/23- changes to reflect return to normal exam arrangements

This is a complete lesson covering sections 5.1.5 g and h of the OCR Biology specification- organisation of the nervous system and structure of the brain. It starts with the organisation of the nervous system into both structural and functional groupings. It the gives students the chance to practise working out which system different actions belong to. It then goes on to cover the structure and function of the human brain including the cerebrum, cerebellum and medulla oblongata. It closes by examining the link between homeostasis and the autonomic nervous system. The lesson includes a starter, full notes, various student led activities and a differentiated summary at the end. All answers are included. I actively try to reduce photocopying, so all of the lesson resources are within the PowerPoint rather than as extra sheets.

It covers the development and use of organohalogens as well as the mechanisms by which CFCs cause damage to the ozone layer. It also includes the other chemicals that may damage the ozone layer and the chemicals that are being used as an alternative. The lesson includes a starter, full notes, various student activities and a fully differentiated summary at the end. All answers included.

This is a complete lesson covering sections 5.1.1 bi and ii of the OCR Biology specification- the role of the liver in homeostasis. It goes through the structure and function of the liver including images to demonstrate the histology of the liver. It then looks at the individual roles of the liver including deamination and detoxification. The lesson ends with looking at the effects of alcohol on the liver and considering the various stages of liver failure The lesson includes a starter, full notes, various student led activities and a differentiated summary at the end. All answers are included. I actively try to reduce photocopying, so all of the lesson resources are within the PowerPoint rather than as extra sheets.

This is a complete lesson covering sections 5.2.2 I, j, k and l of the OCR Biology specification- anaerobic respiration and respiratory substrates. It starts by introducing anaerobic respiration in various organisms including lactate fermentation and alcoholic fermentation.

There are some summary questions to check for understanding before looking at respirometers. The lesson includes a starter, full notes, various student led activities and a differentiated summary at the end. All answers are included. I actively try to reduce photocopying, so all of the lesson resources are within the PowerPoint rather than as extra sheets.

A complete lesson covering section 5.1.1 b and c of the OCR Biology specification- how gene linkage and epistasis can affect the phenotypic ratios and how this can be investigated using Chi square. The lesson starts by introducing sex linkage and then includes some examples of genetic crosses involving colour blindness. It then looks at autosomal linkage again using example crosses to support. The lesson the goes on to look at both recessive and dominant epistasis again using lots of examples to support understanding. The lesson closes by introducing the Chi square test As well as the examples the lesson includes lots of exam questions to show how the skills could be assessed I aim to reduce photocopying so all resources are in the PPT (62 slides in total)
