A complete lesson covering section 4.2.1 c and d of the OCR A level Biology specification- how to calculate and interpret the Simpson’s index of biodiversity. It introduces the index, provides worked examples and an opportunity for students to complete a full calculation. It also introduces the second part of PAG3.1 so students can calculate their own values of biodiversity based on the previous lessons practical work. The lesson includes a starter, full notes, various independent student activities and a differentiated summary at the end. All answers provided.

It is a complete lesson including a starter, full notes, various students activities, review opportunities and a fully differentiated summary activity at the end. Also available in a bundle of two lessons on gas transport /teaching-resource/ocr-a-level-biology-gas-transport-bundle-12393262 or as part of a complete module /teaching-resource/ocr-a-level-biology-animal-transport-bundle-12393269 All answers are 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 complete lesson covering the structure and function of digestive enzymes from AQA Biology and Trilogy B2- Organisation. It starts with a retrieval starter covering content from B1 and earlier in B2 It then goes over enzymes, their digestive function and the lock and key mechanism. This is then recorded through an information hunt (sheet and questions included). Answers provided. The lesson then looks at human digestive enzymes with a summary table to complete. This is then re-caped trjough 9 quick questions There are then a series of exam questions to cover the content from earlier in the lesson. Answers included The final activity is an example 6 mark question with mark scheme All required resources are in the PPT or as separate files

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. It then goes on to look at respiratory substrates and respiratory quotients including their use and calculation. 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.

Helps to deliver some of the maths skills that may be required for the final exam including how to calculate surface area to volume ratio. Includes examples to help support student understanding Also has a homework activity, with answers, to extend the learning from the lesson.

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

This is the third lesson in a set of three covering the structure and function of the KIdney. This lesson specifically focuses on specification point 5.1.2 d- the role of the kidney is osmoregulation. It covers the kidney as an excretory organ as well as the role of ADH in controlling the water balance. It reinforces prior learning regarding negative feedback systems . It also includes how the pituitary gland and hypothalamus are involved. The lesson includes a starter, full notes, a variety of student led activities, and a differentiated summary at the end. All answers included

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 5.2.1 g of the OCR Biology specification- factors that affect the rate of photosynthesis. The lesson starts by discussing the limiting factors of photosynthesis. It then discusses how this can be measured and provides some data for a graph drawing and analysis exercise.
