The is followed by review questions The lesson closes with a pair of exam questions on ADH and its role in the kidney All answers included

A complete lesson covering section 4.6.1.5 of the AQA GCSE Biology specification- DNA structure. The lesson starts with a retrieval starter followed by a quick reminder of DNA and a quick check activity. There are then some notes and a video (link provided to You Tube) on DNA structure followed by some knowledge questions and an exam questions looking at the DNA molecule. The lesson then looks at protein synthesis, the genetic code and mutations again followed by review questions. The lesson ends with two more exam questions All answers provided

A complete lesson covering AQA GCSE Biology section 4.7.2.4 – The Impact of Environmental Change. The lesson begins with a retrieval quiz revisiting key concepts from across the Biology specification. Students are then reminded of the concept of species distribution before being introduced to the key environmental factors that influence it. Understanding is checked through an initial application question. The lesson then explores these factors in more depth, including human impacts, temperature, and water availability. These concepts are reinforced through an exam-style question and explored further via focused case studies. The lesson concludes with an activity on lichen as an indicator species and a final exam-style question assessing understanding of environmental change. All answers provided.

A full lesson covering section 4.2.1h the conservation of species both in situ and ex situ. It covers the difference between the two types of conservation as well as an in-depth look at the advantages and disadvantages of both. It covers various examples of both including wildlife parks, zoos, botanic gardens and seed banks. The lesson includes a starter, full notes, lots of student activities and a differentiated summary at the end All answers included

This is the first of three lessons covering section 5.1.2 of the OCR A level Biology specification. This particular lesson focuses on section Ci, ii and iii which covers the structure and histology of the kidney as well as the function of each of the parts of the nephron. The lesson includes instructions for a kidney dissection which can be used for PAG 01 and 02 or links to a video as an alternative. The lesson includes full notes, a starter, various student activities, and a fully differentiated summary at the end. All answers included

A complete lesson covering section 5.1.1 d of the OCR Biology specification- thermoregulation. This includes both endotherms and ectotherms and the differences between them. Lots of different species as examples. It covers both behavioural and physiological adaptations and the role of the thermoregulatory centre in ectotherms. The lesson includes a starter, full notes, a variety of student activities and a fully differentiated summary at the end All answers included

A complete lesson covering the specification points from AQA Biology and Trilogy-translocation. We have a knowledge rich curriculum so the lesson focuses on the key knowledge required and ensuring that students have remembered this knowledge. Various activities are included including exam practice, application and a do now I actively avoid photocopying so all resources are within the PPT itself All answers provided

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)

A full lesson covering section 4.2.1g of the OCR A level biology specification- the reasons for protecting biodiversity. It covers the economic, aesthetic and ecological reasons for protecting biodiversity. This includes key stone species and the importance of preserving genetic diversity. The lesson includes a starter, full notes, various student activities and a differentiated summary at the end All answers included

A complete lesson covering part of AQA GCSE Biology section 4.5.3.3 Maintaining water and nitrogen balance in the body. The lesson starts with 7 retrieval questions based on paper 1 of AQA Biology. It then moves onto the water balance and the ways in which the body loses and gains water. The lesson then looks at osmosis and cells with some review questions. The next activity looks at the way the filter works with an optional diagram of the kidney to label. Again with review questions and an exam question. The final part of the lesson looks at the filtrate and the way it differs from blood. The lesson closes with an exam question All answers included

A full lesson covering section 5.1.1 a-c of the OCR Biology specification- Homeostasis. The lesson covers the need for communication systems as well as the methods by which cells can communicate with other cells including the example of the dogs vomit fungus. It also introduces the principles of homeostasis including negative and positive feedback as well as the internal conditions that need to maintained. The lesson includes a starter, full notes, a variety of student activities, and a fully differentiated summary at the end. All answers included

This is a complete lesson covering sections 5.2.1 a, b and c of the OCR Biology specification- chloroplasts and chlorophyll. It starts by looking at the compensation point and offering students the chance to analyse some data. It then looks at chloroplasts and how they are adapted to their role before discussing the structure of chlorophyll. The lesson then looks at light absorption spectra and provides data for students to draw a graph of the absorption spectra for chlorophyll a and b. The lesson closes by looking at photosystems and introducing their role in the light dependent reaction. The lesson does not cover chemiosmosis. I cover this during respiration. Please my other free resource: /teaching-resource/resource-12629704 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.
