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 features of intensive rearing of livestock. They will start by being given time to observe their germinating seeds in continuation of RP9 before exploring the transfer of energy through livestock including the equation, P = I - (F + R + U), for this and explaining how rearing animals intensively increases the efficiency of energy conversion. Students will also evaluate data considering economic, environmental and ethical issues involved with increasing productivity in the final part of this lesson.

This lesson continues with Topic 20 - Respiration of the Oxford AQA International A Level Biology course.

Investigating Rate of Respiration (RP8) - Oxford AQA A Level Biology Through this fully resourced lesson students will investigate the effect of temperature on respiration in yeast. This lesson follows the suggested method for Oxford AQA International A Level Biology Required Practical 8. Students will be using the reduction of methylene blue as an indicator of respiratory rate. Through the starter activity I have included the set up of a respirometer as students are expected to know how they can be used to calculate respiratory quotients, although the practical method does not require this.

This lesson summarises Topic 20 - Respiration of the Oxford AQA A Level Biology course. Having also taught Pearson Edexcel for a number of years I can confirm that this lesson is also suitable for the delivery of this course. Revision of Respiration - Oxford AQA A Level Biology Through this fully resourced lesson students will consolidate their understanding of respiration through applying their understanding to unfamiliar scenarios and diagrams. Students will start by recalling their prior knowledge of the structure of mitochondria from AS Unit 1, they will then apply their understanding to a number of different past exam questions before finishing with a reflection of their progress, knowledge and understanding of this topic. Also included in this resource is a number of past paper questions from the student textbook that I have suggested students complete for further revision.

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 analyse how the biological control of pests can increase productivity and reduce environmental impact. They will start by being given time to observe their germinating seeds in continuation of RP9 before exploring the features of an effective pesticide and debating whether chemical pesticides, biological control or a system that incorporates a range of techniques is best for controlling pests and thus increasing agricultural productivity. Students will finish the lesson by completing a mathematical problem solving question.

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.

Through this fully resourced lesson students will differentiate between anaerobic respiration in plants, microorganisms and animals. This includes an understanding of how lactate in animals and ethanol and carbon dioxide are produced in plants as well as how NAD is regenerated in order that ATP can continue to be produced in the absence of oxygen.

This assessment will prepare students for the expectations of A Level Biology, it will also provide teachers with an initial indication of students strengths and areas for development. It mostly includes assessment of knowledge acquired through AS topics and working scientifically skills.

In this fully resourced lesson students will discover the effect of limiting factors on the rate of photosynthesis.

The Link Reaction and Krebs Cycle - Oxford AQA A Level Biology Through this fully resourced lesson students will determine the role of the link reaction and the Krebs Cycle in the production of ATP. Students will start by completing a reading application task, they will then apply their knowledge of respiration so far to a task on the inhibition of cyanide before studying the link reaction and Krebs cycle.

The Electron Transfer Chain - Oxford AQA A Level Biology Through this fully resourced lesson students will evaluate the chemiosmotic theory for ATP production. Students will start by recalling their prior knowledge of glycolysis, the link reaction and Krebs cycle before exploring the detailed events of the electron transfer chain.

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.

In this lesson students will determine the factors that affect the size of a population.

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