A complete lesson covering the calculation of Chi square. It s designed fro specification point 6.1.2c of the OCR course but would be fine for any A level biology course. It starts with a reminder of calculating mean and range before introducing the chi square. The lesson goes through the theory including critical values. It then moves on to a worked example. The rest of the lesson is examples of the calculation including dihybrid inheritance. It also gives a reminder of using a punett square to solve a dihybrid problem. Most examples are based round genetics but one involving mitosis is included. Differentiated summary at the end All answers provided

A full lesson revising content from the AQA Biology module- bioenergetics. This lesson covers photosynthesis and is suitable for both trilogy and the Biology science GCSE. The lesson starts by revising the reactants for photosynthesis and the equation along with the uses of glucose. It then has a quick summary activity before looking at leaf structure. The lesson then moves on to limiting factors with a series of data based activities. In between this the lesson looks at the required practical and covers the method as well as some extension questions. The lesson closes by looking at photosynthesis in ecosystems by considering the carbon cycle (from B7) but also the role played by photosynthesis in determining which plants can grow in differetn areas. All answers provided Requires no printing as all activities are in the PowerPoint

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
