This is a fully-resourced lesson that covers the details of specification point 5.1.2 (e) of the OCR A-level Biology A specification which states that students should be able to demonstrate and apply an understanding of the effects of kidney failure and its potential treatments. This lesson consists of an engaging PowerPoint (55 slides) and associated differentiated worksheets that look at the diagnosis of a number of different kidney-related conditions and the potential treatments for kidney failure. This lesson is designed to get the students to take on the numerous roles of a doctor who works in the renal ward which include testing, diagnosis and treatment. Having obtained measurements by GFR and results by taking urine samples, hey are challenged to use their knowledge of the function of the kidney to study urine samples (and the accompanying GP’s notes) to diagnose one of four conditions. They then have to write a letter to the patient to explain how they made this diagnosis, again focusing on their knowledge of the structure and functions of the Bowman’s capsule and PCT. The rest of the lesson focuses on haemodialysis, peritoneal dialysis and kidney transplant. There are regular progress checks throughout the lesson so that students can assess their understanding and there are a number of homework activities included in the lesson. This lesson is designed for A-level students who are studying the OCR A-level Biology specification and ties in nicely with the other uploaded lessons on this organ which include the structure and function of the nephron, ultrafiltration, selective reabsorption and osmoregulation.

A detailed lesson presentation (37 slides) and associated worksheets that guide students through the DNA sequencing method called pyrosequencing. The lesson focusses on the numerous enzymes and substrates which are involved in the cascade of events which eventually leads to the production of light when the conversion from luciferin to oxyluciferin occurs. A step by step guide is used to show the students how these events occur and the different outcomes are explored. There are regular progress checks throughout the lesson so that students can assess their understanding of this topic and the links to similar topics. This lesson has been designed for A-level students and above

This detailed lesson describes the principles of DNA sequencing and has been designed to cover the first part of point 6.1.3 (a) of the OCR A-level Biology A specification. Fred Sanger’s chain termination method is used as the example to guide the students through the details of each step. The lesson begins with a focus on the common ingredients of the process such as DNA polymerase, DNA nucleotides and primers. Links are made to module 2.1.3 where nucleic acids were initially met through a series of prior knowledge check questions. Time is then taken to explain why these short lengths of synthesised nucleotides are necessary and this will support students when primers are met in the PCR and genetic engineering. Moving forwards, students will recognise how the modification to the nucleotide means that the chain terminates once a modified nucleotide is added into the sequence and that these have been radioactively labelled. Gel electrophoresis is introduced and an outline of the process given to provide knowledge to build on when this is encountered later in the module. A series of exam-style questions allow students to assess their understanding of this potentially difficult topic before students are encouraged to consider the limitations of the method so they are prepared to meet the new methods in upcoming lessons. A number of quiz competitions run throughout the lesson to maintain engagement and to introduce terms and values in a memorable way

This is a detailed, engaging and fully-resourced REVISION LESSON which allows students of all abilities to assess their understanding of the content in module 2.1.3 (Nucleotides and nucleic acids) of the OCR A-level Biology A specification. Considerable time has been taken to design the lesson to include a wide range of activities to motivate the students whilst they evaluate their knowledge of DNA, RNA and the roles of these nucleic acids in DNA replication and protein synthesis. Most of the tasks have been differentiated so that students of differing abilities can access the work and move forward as a result of the tasks at hand. This lesson has been planned to cover as much of the specification as possible but the following sub-topics have received particular attention: The structure of DNA Phosphorylated nucleotides DNA replication Transcription and translation Gene mutations and their affect on the primary structure of a polypeptide The structure of RNA In addition to a focus on the current topic, links are made throughout the lesson to other topics such as the journey of an extracellular protein following translation and the cell cycle.

An engaging lesson presentation (32 slides) and differentiated worksheets that look at the meaning of the substances termed monoclonal antibodies, explains how they are produced and explores their different applications. The lesson begins by breaking the term down into three parts so that students can understand that these substances are proteins that attach to antigens and come from a single clone of cells. Students will meet key terms such as lymphocytes, myelomas and hybridomas and will be able to link them to understand how these antibodies are produced. Moving forwards, time is taken to focus on the application of monoclonal antibodies in pregnancy tests. There are regular progress checks throughout the lesson so that students can assess their understanding and a set homework is included as part of the lesson. This lesson has been written for GCSE students but can be used with lower ability A-level students who are studying this topic

This fully-resourced lesson looks at the type of circulatory system found in a mammal (double, closed) and considers how the pulmonary circulation differs from the systemic circulation. The engaging PowerPoint and accompanying resources have been designed to cover point 3.1.2 (b) of the OCR A-level Biology A specification The lesson begins with a focus on the meaning of a double circulatory system and checks that students are clear in the understanding that the blood passes through the heart twice per cycle of the body. Beginning with the pulmonary circulation, students will recall that the pulmonary artery carries the blood from the right ventricle to the lungs. An opportunity is taken at this point to check on their knowledge of inhalation and the respiratory system as well as the gas exchange between the alveoli and the capillary bed. A quick quiz is used to introduce arterioles and students will learn that these blood vessels play a crucial role in the changes in blood pressure that prevent the capillaries from damage. When looking at the systemic circulation, time is taken to look at the coronary arteries and renal artery as students have to be aware of these vessels in addition to the ones associated with the heart. In the final part of the lesson, students are challenged to explain how the structure of the heart generates a higher pressure in the systemic circulation and then to explain why the differing pressures are necessary. This lesson has been written to tie in with the other uploaded lessons from topic 3.1.2 (transport in animals)
