A fully-resourced lesson that looks at the different sampling methods that can be used to estimate the populations of animals and plants in a habitat and to analyse how their distribution is affected, The lesson includes a detailed and engaging lesson presentation (56 slides) and differentiated worksheets so that students of different abilities are challenged and can access the work. The lesson begins by looking at the use of a quadrat to estimate the population of plants in a habitat. There is a focus on the mathematical calculations associated with the method and students are given hints and worked examples so that any common misconceptions are addressed. Moving forwards, students are introduced to the capture-mark-recapture technique to sample animals. The rest of the lesson looks at alternative pieces of apparatus, such as the sweep net, and discusses situations when these would be used. This lesson has been written for GCSE students (14 - 16 year olds in the UK) but is appropriate for both younger students who are learning about ecology and also for A-level students who need a recap on this topic.

This is a fully-resourced lesson that explores the meaning of irradiation and contamination and challenges the students to make links to the different types of radiation in order to state which type of radiation is most dangerous outside of the body and inside the body. This lesson includes an engaging lesson presentation (28 slides) and a differentiated worksheet which gives assistance to those students who find the task of writing the letter difficult. The lesson has been written to include real life examples to try to make the subject matter more relevant to the students. Therefore, whilst meeting the term contamination, they will briefly read about the incident with Alexander Litvinenko in 2006 to understand how the radiation entered the body. Moving forwards, students will learn that there are examples of consensual contamination such as the injection of an isotope to act as a tracer. At this point of the lesson, links are made to the topic of decay and half-lives and students are challenged to pick an appropriate isotope based on the half-life and then to write a letter to the patient explaining why they made their choice. The remainder of the lesson challenges students to decide which type or types of radiation are most dangerous when an individual is irradiated or contaminated and to explain their answers. This type of progress check can be found throughout the lesson along with a number of quick competitions which act to maintain engagement as well as introduce new terms. This lesson has been written for GCSE aged students

This lesson includes a detailed and engaging lesson presentation (42 slides) and differentiated worksheets that include exam questions that can be set as homework. There is a lot of key terminology associated with this topic and time is taken to ensure that students understand the meaning of each of these terms before moving forwards. Students are introduced to the different types of solutions and then a step-by-step guide is used to show them how to compare the water potential of the solution and the cell and then how this will determine which was water moves. The main task is differentiated so that students are challenged and can access the work. This lesson has been designed for GCSE students (14 - 16 year olds in the UK) but is also suitable for A-level students

A detailed lesson presentation and associated question worksheet which uses a step by step guide and numerous worked examples to show students how to draw genetic crosses to calculate offspring percentages. Before students are able to draw genetic diagrams, they need to understand and be able to use genetic terminology so this is the focus for the start of the lesson. Time is taken to go over the meaning of dominant and recessive alleles, genotypes and phenotypes. Moving forwards, students will be challenged to link genotypes to phenotypes for both dominant and recessive disorders and common misconceptions such as carriers in recessive disorders are explained. Finally, a 5 step guide is used to walk students through drawing genetic diagrams. Students are then given a chance to apply their new-found knowledge to questions about the inheritance of cystic fibrosis and polydactyly. Progress checks have been written into the lesson at regular intervals so that students can assess their understanding. This lesson has been designed for GCSE students but is perfectly suitable for A-level students who are studying the topic of monogenic inheritance

The detailed and engaging PowerPoint and accompanying resources have been designed to cover point 2.1 (v) of the Edexcel A-level Biology B specification As cells are the building blocks of living organisms, it makes sense that they would be heavily involved in all of the 10 topics in the Edexcel A-level B course and intricate planning has ensured that links are made to topic 1 and details are provided to link to the upcoming topics. A wide range of activities, that include exam-style questions, class discussion points and quick quiz competitions, will maintain motivation and engagement whilst covering the finer details of the following structures and organelles: nucleus nucleolus ribosomes rough endoplasmic reticulum Golgi apparatus lysosomes smooth endoplasmic reticulum mitochondria cell surface membrane centrioles vacuole (+ tonoplast) chloroplasts cell wall As mentioned above, all of the worksheets have been differentiated to support students of differing abilities whilst maintaining challenge Due to the detail that is included in this lesson, it is estimated that it will take in excess of 3 hours of allocated A-level teaching time to cover the work

An engaging and detailed lesson presentation (53 slides) and associated worksheets that looks at the properties and functions of enzymes and explores how the rate of enzyme-controlled reactions changes with changes in conditions. The lesson begins by using a quick quiz competition to introduce the key terms of active site and substrate. Diagrams accompany the important descriptions so that students can visualise how enzymes are specific to a single substrate and will form enzyme-substrate complexes with only them. Emil Fischer’s lock and key hypothesis is briefly discussed so that the correlation between the hypothesis and key terms can be made. Students are shown how most enzymes or groups of enzymes can be named by remembering two rules and they will be tested on this through a second competition. At this point, a progress check is used to allow the students to assess their understanding and ability to bring the information together for enzyme function. The rest of the lesson looks at how changing the temperature and pH will affect the rate of an enzyme controlled reaction. Students will meet the graph shapes that accompany both of these factors and then are helped with the explanation of the trend which is normally poorly done in exam questions. This lesson has been designed for GCSE students.

An informative lesson presentation (38 slides) that looks at a range of non-communicable diseases and also explores how risk factors can increase the chances of an individual having one of these diseases. The lesson begins by looking at CHD so that students can recognise that this is a non-communicable disease and check on their understanding of this key term. Moving forwards, a step by step question and answer format is used to show students how to form a long answer. Key terminology such as thrombosis and atherosclerosis are introduced using quick quiz competitions which act to maintain the engagement. The rest of the lesson focuses on a range of risk factors for cardiovascular diseases and time is taken to deepen knowledge of the human anatomy by challenging students to link the names of arteries to the organs that they supply. Progress checks have been written into the lesson at regular intervals so that students can constantly assess their understanding and any misconceptions can be addressed. This lesson has been written for GCSE students (14 - 16 year olds in the UK)

An informative lesson which guides students through the commonly misunderstood topic of drawing free body diagrams and using them to calculate resultant forces. The lesson begins by ensuring that students understand that force is a vector quantity and therefore arrows in diagrams can be used to show the magnitude and direction. Drawing free body diagrams is poorly understood and therefore time is taken to go through the three key steps in drawing these diagrams. Each of these steps is demonstrated in a number of examples, so students are able to visualise how to construct the diagrams before they are given the opportunity to apply their new-found knowledge. The rest of the lesson focuses on calculating resultant forces when the forces act in the same plane and also when they are at angles to each other. Again, worked examples are shown before students are challenged to apply. Progress checks are written into the lesson at regular intervals so that students can constantly assess their understanding and any misconceptions can be addressed. This lesson has been designed for GCSE students

An engaging and informative lesson presentation (49 slides) looks at the differences between contact and non-contact forces and focuses on enabling students to describe and recognise them. This lesson has been written for GCSE students but could be used in higher ability KS3 lessons with students who are looking to progress their knowledge. The lesson begins by introducing the fact that forces can be grouped into these two categories and initial definitions are used to ease the students into the lesson. To follow on from this a competition called “FORCE it together” is used. This engaging game challenges the students to spot the name of a force which is in anagram form and then once it has been identified, they have to determine whether it would be a contact or non-contact force. As each force is met, key details are given and discussed. More time is given to areas which can cause problems for students, such as the use of weight and gravity force and whether they are actually different. Moving forwards, a rugby tackle is used to show the numerous forces that interact in everyday situations, before students are challenged to identify more forces in sports of their choice. Students will recall/learn that force is a vector quantity and therefore is represented in diagrams using arrows. Once again, this lesson focuses on showing them how these arrows can be used differently with the different types of forces. Students are briefly introduced to the idea of a free body diagram and an understanding check is used to see whether they can identify friction, gravity force and normal contact force from the arrows. Progress checks like this are written into the lesson at regular intervals, in a range of formats, so that students are constantly assessing their understanding. The final part of the lesson is one more quick competition where students have to use their knowledge of the forces to form words.

This is a fully-resourced REVISION lesson that consists of an engaging PowerPoint (154 slides) and associated worksheets that challenge the students on their knowledge of topics B1 - B4 (Cell Biology, Organisation, Infection and response and Bioenergetics) of the AQA GCSE Combined Science Trilogy specification and can be assessed on PAPER 1. A wide range of activities have been written into the lesson to maintain motivation and these tasks include exam questions (with answers), understanding checks, differentiated tasks and quiz competitions. The lesson has been designed to include as much which of the content that can be assessed in paper, but the following sub-topics have been given particular attention: Eukaryotic and prokaryotic cells Structure of a bacterium The functions of the components of blood Specialised cells Active transport Osmosis Structure of DNA Mitosis and the cell cycle Functions of the organelles of animal and plant cells Electron microscopy Calculating size Arteries and veins The risk factors of CHD CHD treatments The structure of the heart Bacterial, fungal and viral diseases The mathematic elements of the Combined Science specification are challenged throughout the resource.
