Respiratory Substrates - Oxford AQA A Level Biology Through this fully resourced lesson students will determine the respiratory quotient of different respiratory substrates. Students will start by recalling their prior knowledge of biological molecules from AS Unit 1, they will then discuss how different respiratory substrates enter at different stages of respiration before exploring the equation and concept of respiratory quotients.

This lesson continues with Topic 21 - Energy and Ecosystems of the Oxford AQA International A Level Biology course. Having also taught AQA and Pearson Edexcel for a number of years I can confirm that this lesson is also suitable for the delivery of these courses. Through this fully resourced lesson students will explore how productivity is increased in agricultural ecosystems. They will start by compare natural and agricultural ecosystems. They will then observe their germinating seeds in continuation of RP9 before exploring the concept of productivity including calculations and studying how agricultural ecosystems are manipulated to improve productivity through creating a a leaflet or presentation to educate young farmers about how to increase the productivity of their crops.

Through this fully resourced lesson students will determine the hormones produced by a number of different endocrine glands. Students will first name and label the main endocrine glands in the body, they will then describe the role a number of different hormones have in the body through a short research and presentation task, they will then finish by comparing what is meant by primary sexual characteristics and secondary characteristics. Throughout the lesson students will also have the opportunity to apply their knowledge and understanding to exam style questions.

Through this fully resourced lesson students will be introduced to the endocrine system. The learning objective for this lesson is for students to explain the function of the endocrine system. They will first define the term hormone and give examples, they will then describe what the endocrine system is and its role in homeostasis and they will finally compare the endocrine and nervous systems that they should have learned previously. Students will also have the opportunity to apply their knowledge and understanding to exam style questions.

Through this fully resourced lesson students will determine allele and genotype frequencies based upon the Hardy-Weinberg principle. This lesson requires students to have already been introduced to the Hardy-Weinberg principle and its conditions as well as the equation p+q=1 and what it represents. Students will first determine how genotypes are represented by the Hardy-Weinberg principle (p2 + 2pq + q2 = 1). Students will then calculate a number of allele and genotype frequencies based upon exam style questions, worked answers are then provided for each question. Students will finish by applying their knowledge of the Hardy-Weinberg principle to more exam style questions.

This assessment has been designed to be used approximately in week 6 of the Oxford AQA International A Level Biology (Year 13/Grade 12) course once the following chapters have been taught: Topic 18 Populations Topic 19 Photosynthesis Topic 20 Respiration This is a 20 mark assessment that students should be given 25-30 minutes to complete. This resource includes the assessment, mark scheme and a supporting lesson PowerPoint that should be used as a revision starter activity and reflection plenary.

This collection of teaching resources finalises the Populations (Chapter 18) topic of the Oxford AQA International A Level course. These resources are also suitable for the AQA and Pearson Edexcel courses. Through this series of 4 fully resourced lessons students will acquire knowledge and skills in the following areas: Lesson 1: Succession - Students will determine the stages of succession from colonisation to the formation of a climax community. Lesson 2: Warming to Succession - Students will discuss the impact of global warming on succession. Lesson 3: Conservation of Habitats - Students will suggest how managing succession can help to conserve habitats. Lesson 4: Revision of Populations - Students will apply their knowledge of populations and ecology to past paper questions.

In this lesson students will discuss how predator-prey relationships cause cyclical fluctuations in population.

In this fully resources lesson students will outline the events of the Calvin Cycle in the production of useful organic molecules.

Through this fully resourced lesson students will determine how natural selection is the mechanism for evolution. Students will first identify how adaptations lead to increased survival rate, they will then describe the 4 basic principles of natural selection and finally explain why natural selection could not occur if organisms did not have to compete for resources. Students will also have the opportunity to apply their knowledge and understanding to exam style questions.

Through this fully resourced lesson students will consider the two main treatment methods for kidney failure. They will identify the two main treatments for kidney failure and they will then describe these treatment methods through interpretation of diagrams and reading comprehension. They will finally evaluate the use of kidney dialysis and transplants through an extended writing task. Students will also have the opportunity to apply their knowledge and understanding to exam style questions.

Through this fully resourced lesson students will explore the human excretory organs and their products. They will first define excretion, then will then differentiate between excretion and egestion before finally determining the waste products of the main excretory organs. Students will also have the opportunity to apply their knowledge and understanding to exam style questions.

This lesson continues with my series of lessons on Topic 21 - Energy and Ecosystems of the Oxford AQA International A Level Biology course. In the lesson series this lesson should be used after students have sat the week 6 assessment on Topics 18-20 and the teacher has marked this to be returned at the start of the lesson. Through this fully resourced lesson students will reflect upon their knowledge and understanding of populations, photosynthesis and respiration. They will identify their strengths and areas for development and they will respond to the feedback they were given by their teacher. They will then prepare for RP9, investigating the effect of competition on seedling growth, as this needs to be completed over a number of lessons. In this resourse package I have included the week 6 assessment, mark scheme, RP9 student and teacher sheet from Oxford AQA and an accompanying PowerPoint to guide students and teachers through the lesson.

This lesson continues with Topic 21 - Energy and Ecosystems of the Oxford AQA International A Level Biology course. Through this fully resourced lesson students will consolidate their understanding of energy and ecosystems through applying their understanding to unfamiliar scenarios and diagrams. They will start by being given time to observe their germinating seeds in continuation of RP9 for the last time. In this lesson they will also take measurements of the length of the root and shoot of their germinated seeds and carry out a Spearman’s rank calculation in order to see if there is a significant difference in germination and initial growth in the seedlings at different densities of sowing. The PowerPoint resource guides students through this process. Students will then attempt a number of past paper questions and reflect upon reflect upon their understanding of Chapter 21 - Energy and Ecosystems and their progress this academic year so far.
