A resourced lesson which looks at the chemical reaction that is aerobic respiration and ensures that students can apply their knowledge to application questions which challenge them to make links to related topics. The lesson includes an engaging lesson presentation (27 slides) and an associated worksheet containing questions. The lesson begins by challenging the students to recognise a definition for breathing and a definition for respiration. This is aimed at helping them to understand that these are different processes as this is a common misconception made by students. Moving forwards, key details about aerobic respiration are introduced to the students through a range of tasks which include competitions to maintain engagement. Time is taken to ensure that students become familiar with ATP and understand that this is the energy store which will be broken down to release energy for the activities that occur in a living organism. The remainder of the lesson challenges the students to take their new found knowledge of aerobic respiration and apply it to range of unfamiliar situations such as explaining why a root hair cell would have such a large number of mitochondria. There are regular progress checks throughout the lesson to allow the students to check on their understanding. As always, the lesson finishes with a slide containing advanced terminology so that students who have aspirations to take A-level Biology can extend and deepen their knowledge

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

A detailed lesson presentation which guides students through calculating the current, potential difference and resistance in series and parallel circuits.

Progress checks have been written throughout the lesson so that students can constantly assess their understanding. This lesson has been designed for GCSE students

An engaging lesson presentation and associated worksheet that looks at the use of antibiotics to treat bacterial infections and the raises the issue of the potential over-use of these substances. The lesson begins by getting the students to recognise the difference between three key terms that begin with anti (antibiotics, antivirals, antiseptics). Students will be introduced to the idea that antibiotics are specific to a small range of bacteria and therefore the correct one has to be selected before being prescribed. Moving forwards, students will meet the idea of the zone of inhibition and will understand how the size of this zone can be used as an indicator to the effectiveness of the treatment. Students are shown how to calculate the size of the zone and then are tested on their ability to apply this mathemetical knowledge. Finally, time is taken to look at the links to the topic of natural selection to explain how some bacteria are resistant to certain antibiotics. There are regular progress checks throughout the lesson so that students can assess their understanding. This lesson has been designed for GCSE students but could be used as an introduction with A-level Biology students who are about to begin the topic of immunity.

The lesson includes an engaging lesson presentation (45 slides) and an associated worksheet for the calculations. The lesson begins by introducing the term stopping distance and then challenging students to recognise that both the distance travelled during the driver’s reaction time and under the braking force will contribute to this. Students are constantly challenged to think about the factors that would cause either the thinking or braking distance to increase and to be able to explain why scientifically. Moving forwards, the mathematical element that is associated with this topic is explored as students are shown how to calculate the braking distance at different speeds as well as convert between speeds in miles per hour and metres per second. There is also a set homework included as part of the lesson. There are regular progress checks written into the lesson so that students can assess their understanding. This lesson has been written for GCSE students but could be used with those at KS3.

This fully-resourced lesson guides students through the use of the Hardy-Weinberg equations to determine the frequency of alleles and genotypes in a population. Both the detailed PowerPoint and differentiated practice questions on a worksheet have been designed to cover point 6.1.2 (f) of the OCR A-level Biology specification which states that students should be able to demonstrate and apply their knowledge and understanding of the use of the principle to calculate allele frequencies in populations. The lesson begins by looking at the two equations and ensuring that students understand the meaning of each of the terms. The recessive condition, cystic fibrosis, is used as an example so that students can start to apply their knowledge and assess whether they understand which genotypes go with which term. Moving forwards, a step-by-step guide is used to show students how to answer a question. Tips are given during the guide so that common misconceptions and mistakes are addressed immediately.

This fully-resourced lesson explores the inheritance of sex-linked diseases in humans and then challenges the students to apply their knowledge to examples in other animals. The detailed PowerPoint and associated differentiated resources have been designed to cover the part of point 6.1.2 (b[i]) of the OCR A-level Biology A specification which states that students should be able to demonstrate and apply their knowledge and understanding of genetic diagrams which include sex-linkage. Key genetic terminology is used throughout and the lesson begins with a check on their ability to identify the definition of homologous chromosomes. Students will recall that the sex chromosomes are not fully homologous and that the smaller Y chromosome lacks some of the genes that are found on the X. This leads into one of the numerous discussion points, where students are encouraged to consider whether females or males are more likely to suffer from sex-linked diseases. In terms of humans, the lesson focuses on haemophilia and red-green colour blindness and a step-by-step guide is used to demonstrate how these specific genetic diagrams should be constructed and how the phenotypes should then be interpreted. The final tasks of the lesson challenge the students to carry out a dihybrid cross that involves a sex-linked disease and an autosomal disease before applying their knowledge to a question about chickens and how the rate of feather production in chicks can be used to determine gender. All of the tasks are differentiated so that students of differing abilities can access the work and all exam questions have fully-explained, visual markschemes to allow them to assess their progress and address any misconceptions.
