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.
