This revision resource has been designed with the simple aim of motivating the students whilst they assess their understanding of the content found in module 4.2.2 (Classification and evolution) of the OCR A-level Biology A specification. This module is often brushed over by students which leads to misconceptions and therefore time has been taken to explain the important concepts so that key points are recalled and retained.

The range of activities include exam questions and understanding checks as well as quiz competitions to maintain student engagement.

This revision resource contains an engaging and detailed PowerPoint (66 slides) and associated worksheets, all of which are differentiated to allow students of different abilities to access the work.

This is a fully-resourced lesson which uses exam-style questions, quiz rounds, quick tasks and discussion points to challenge students on their understanding of the content of topics B4 - B6, that will assessed on PAPER 2. It has been specifically designed for students on the OCR Gateway A GCSE Combined Science course who will be taking the FOUNDATION TIER examinations but is also suitable for students taking the higher tier who need to ensure that the fundamentals are known and understood. The lesson has been written to take place at the hospital and the students will visit the various wards and health clinics day to check on their knowledge of the following sub-topics : Cancer The production of gametes by meiosis The meaning of diploid and haploid Sex determination The difference between communicable and non-communicable diseases Diseases caused by bacteria, viruses, fungi and protists Treatment of bacterial infections using antibiotics Evolution by natural selection in bacteria Vaccinations Genetic terminology Inheritance of disorders caused by dominant and recessive alleles Risk factors of non-communicable diseases Ecosystems The carbon cycle and the increase in carbon dioxide levels In order to maintain challenge whilst ensuring that all abilities can access the questions, the majority of the tasks have been differentiated and students can ask for extra support when they are unable to begin a question. Step-by-step guides have also been written into the lesson to walk students through some of the more difficult concepts such as genetic diagrams and interpreting the results and evolution by natural selection. Due to the extensiveness of this revision lesson, it is estimated that it will take in excess of 3 teaching hours to complete the tasks and therefore this can be used at different points throughout the duration of the course as well as acting as a final revision before the PAPER 2 exam.

A concise lesson presentation that focuses on the key details that students need to know about diodes for the GCSE examinations. The lesson begins by introducing the idea that diodes only allow current to flow in one direction. Moving forwards, time is taken to go through the potential difference vs current graph in 3 parts so that students can explain how the diode functions. Moving forwards, students will meet a LED and then in the style commonly associated with the 6 mark exam question, they are challenged to use data in a table to compare the effectiveness of a LED against other light bulbs.

An engaging lesson presentation that runs the lesson in a quiz format, with numerous rounds, in order to introduce the students to the different stages of the life cycle of a star. The lesson begins by introducing students to the first three stages (nebula, protostar, main sequence) which all stars go through regardless of their mass. Key details about each stage are discussed and considered. Moving forwards, this lesson ensures that students understand that the stages after the main sequence are dependent upon the mass of the star. Key links are made to associated topics such as nuclear fusion. This lesson has been designed for GCSE students but could be used with KS3 students if they are doing a project on space and stars

This detailed and clear lesson describes and explains how the electron transport chain and the chemiosmotic theory are involved in the synthesis of ATP by oxidative phosphorylation. The PowerPoint has been designed to cover the sixth part of point 5.2 of the AQA A-level Biology A specification and also looks at the role of the enzyme, ATP synthase. The lesson begins with a discussion about the starting point of the reaction. In the previous stages, the starting molecule was the final product of the last stage but in this stage, it is the reduced coenzymes which release their hydrogen atoms. Moving forwards, the process of oxidative phosphorylation is covered in 7 steps and at each point, key facts are discussed and explored in detail to enable a deep understanding to be developed. Students will see how the proton gradient is created and that the flow of protons down the channel associated with ATP synthase results in a conformational change and the addition of phosphate groups to ADP. Understanding checks are included throughout the lesson to enable the students to assess their progress. This lesson has been written to tie in with the other uploaded lessons on glycolysis, the Link reaction and Krebs cycle and anaerobic respiration.

This detailed lesson introduces ATP as the body’s energy store and energy currency and explains how PC, glycogen and fat are sources for its re-synthesis during exercise. The engaging PowerPoint has been designed to cover the ATP and energy transfer section of topic 1.1.c as detailed in the OCR A-level PE specification. The lesson begins by challenging the students to recognise that the link between muscle contraction, active transport and the conduction of electrical impulses is the need for energy. A number of quick quiz competitions are used throughout the lesson to maintain engagement and to introduce key terms and values and the first quiz round will result in the students meeting adenosine tri-phosphate (ATP). Time is taken to describe the structure of this energy store and to explain how it will be broken down into ADP and a phosphate and that this mechanism results in the release of energy for muscle contraction. Importantly, students will learn that the ATP stored in muscles will only allow for the first few seconds of contraction and therefore if exercise and contraction are to continue, the ATP will need to be re-synthesised. The main part of the lesson explores how phosphocreatine, glycogen and fats are sources for this re-synthesis. Key details about each of these sources are provided and explained and links are made to upcoming lessons on the energy systems as well as to topics already covered such as the different types of muscle fibres. The final round of the quiz, which is called “What’s your SOURCE?” acts a final understanding check as the teams of students have to recognise one of the 4 energy sources based on a description. This lesson has been specifically written to tie in with the next lessons on the ATP-PC, glycolytic and aerobic energy systems.
