This fully-resourced lesson looks at the process and site of the Krebs cycle and explains the importance of decarboxylation, dehydrogenation, the reduction of NAD and FAD and substrate level phosphorylation. The engaging and detailed PowerPoint and accompanying resource have both been designed to cover point 5.2.2 (e) of the OCR A-level Biology A specification and includes the formation of citrate from the acetyl group of acetyl CoA and oxaloacetate and the regeneration of this four carbon molecule. The lesson begins with a version of the Impossible game where students have to spot the connection between 8 of the 9 terms and will ultimately learn that this next stage is called the Krebs cycle. The main part of the lesson challenges the students to use descriptions of the main steps of the cycle to continue their diagram of the oxidation-reduction reactions. Students are continually exposed to key terminology such as decarboxylation and dehydrogenation and they will learn where carbon dioxide is lost and reduced NAD and FAD are generated. They will also recognise that ATP is synthesised by substrate level phosphorylation. The final task challenges them to apply their knowledge of the cycle to work out the numbers of the different products and to calculate the number of ATP that must be produced in the next stage if the theoretical yield of 32ATP is to be achieved. This lesson has been designed to tie in with the other uploaded lessons on glycolysis, anaerobic respiration, the Link reaction, oxidative phosphorylation and respiratory substrates

An informative lesson presentation (26 slides) that shows students how to convert between numbers and standard form (and the other way) so they are able to understand when these are used in Science questions. The lesson begins by guiding them through how to change numbers to standard form and explains when a power of 10 that is positive will be achieved and when it will be negative. Students are given the opportunity to see these used in a Science question and there is a cross-subject link as they are also required to convert between units. A number of competitions are used near the end of the lesson to maintain motivation and to allow the students to check their progress in a fun way This lesson has been designed for GCSE students but is suitable for KS3

An engaging lesson presentation (33 slides) that looks at the key details of asexual reproduction, examines the process in bacteria and plants and also considers the advantages and disadvantages. The lesson begins by challenging the students to discuss whether reproduction always requires two (parents). Students will see how only one parent is involved in this type of reproduction and will focus on how it takes place in bacteria. Moving forwards, students will be introduced to the methods of runners, bulbs and tubers in plants. By making connections to natural selection, students will be challenged to think about the benefits of asexual reproduction. There are regular progress checks throughout the lesson so that students can assess their understanding. This lesson is suitable for both KS3 and GCSE students
