An engaging lesson presentation (37 slides) which gets students to test their practical skills by carrying out the four identification tests for oxygen, hydrogen, carbon dioxide and chlorine. The lesson begins by using a competition called “Guess the gas” where students have to used clues to identify the four colourless gases which will be used in the lesson. Moving forwards, students will meet the pieces of equipment that will be used in these tests. Practical instructions for each of the tests are included in the lesson so that students can produce the gas and then carry out the test. 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

A fully-resourced lesson which looks at how the sex chromosomes which determine gender are inherited in humans. The lesson includes an engaging lesson presentation (24 slides) and an associated worksheet containing knowledge recall and application questions. The lesson begins with a range of different quiz competitions which enable the students to get the answers of X, Y, zygote and 23. With a little bit of assistance, students are challenged to bring these terms together to complete a passage about how the inheritance of either an XX genotype will lead to a female or a XY genotype will lead to a male. Moving forwards, students are told how they will be expected to be able to construct a genetic diagram to show the inheritance of gender and so are given a quick recap before being challenged to do just that. The last part of the lesson gets students to discuss and consider whether females or males are responsible for determining sex in terms of their gametes. There are regular progress checks throughout the lesson to allow the students to check on their understanding. The lesson has been written for GCSE students primarily but the content is suitable for both KS3 and even A-level students

A fully-resourced lesson which looks at the structures of arteries, veins and capillaries and ensures that students can relate these features to their respective functions. The lesson includes an engaging lesson presentation (41 slides) and a differentiated worksheet The lesson begins by getting the students to come up with a really simple rule to remind themselves that arteries carry blood away from the heart. They are then challenged to extend this definition by considering the pressure of the blood found in arteries. Students will learn that most arteries carry oxygenated blood but will consider and recall the artery which is the exception to the rule. Students are shown a diagram of the basic structure of the artery and the reasons for the narrow lumen and thick muscular wall are explained. Moving forwards, students are challenged to use the work on arteries to sketch a diagram of a vein and to explain why they have given this vessel certain features. A quick competition is then used to check their understand of the work so far whilst introducing valves and again they are given a chance to work out which blood vessel would need these structures in their lumen. The remainder of the lesson focuses on the capillary and time is taken to relate the features to an actual example involving the alveoli of the lungs. 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 resourced lesson which looks at three of the main components of blood and ensures that students can relate their features to their function. The lesson includes an engaging lesson presentation (31 slides) and an associated worksheet The lesson begins by challenging the students to recognise blood from a description of some of its contents. This will enable students to identify some of the substances like hormones and urea that are carried in the plasma. Moving forwards, the rest of the lesson takes a format where the students have to act as recruitment consultants. They have been given 3 job roles to fill and once they have decided on the right candidates for the job, they need to be able to explain why these have been chosen. Students will go study the red and white blood cells and platelets, focusing on how their different specialised features enable them to effectively carry out their respective functions. Students will be able to compare the cells in terms of size, number of nuclei and ultimately explain why they have their features. There are regular progress checks throughout the lesson to allow the students to check on their understanding. This lesson has been designed for GCSE students but is perfectly suitable to be used with KS3 students who are studying the circulatory system

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 fully-resourced lesson which looks at the saturated hydrocarbons known as the alkanes and focuses on their structure and reactions. The lesson includes an engaging lesson presentation (38 slides) and an associated worksheet which is differentiated. The lesson begins with the introduction of the name of this group and then a step-by-step guide is used to show students how to draw the displayed formula. Once the first four have been drawn, students are shown how to calculate the general formula for the alkenes and then challenged to do the same for the alkanes. Moving forwards, students will meet the key term, saturated, and time is taken to ensure that the meaning of this word is understood in the context of this lesson. Once they have been introduced to bromine water, students are challenged to work out what will happen when this substance is added to an alkane and they have to explain their answer. The remainder of the lesson looks at the complete and incomplete combustion of the alkanes, focusing on the different products of these reactions and specifically the problems associated with carbon monoxide. There are regular progress checks throughout the lesson to allow the students to check on their understanding.

An informative and student-led lesson presentation (32 slides), accompanied by a reaction diagram and task worksheet, which together look at the key details of nuclear fission reactions. The lesson begins by introducing the students to the name of this reaction and to that of a neutron before they are challenged to recall the properties of this sub-atomic particle as this knowledge plays an important role in their understanding. Moving forwards, students will learn that two isotopes of uranium are involved and will discover and work out how one isotope is changed into the other. Diagrams accompany the theory throughout so that students can visualise how the reaction progresses. They are shown how to work out the two daughter nuclei that are produced in the reaction and how an equation can be written to represent nuclear fission. Progress checks have been written into the lesson at regular intervals so that students can constantly assess their understanding and any misconceptions can be immediately addressed. This lesson has been designed for GCSE students (14 - 16 year olds in the UK)

An engaging, practical-based lesson presentation (22 slides), accompanied by a practical worksheet and application questions which together explore how the extension of a spring is related to force according to Hooke’s Law. The lesson begins by introducing the name of the law and looking at the equation which connects the force, extension and spring constant. As spring constant is likely to be a new term to students, time is taken to look at the definition of this key term. Students are given hints throughout the lesson about potential issues to look out for, including the unit of spring constant being N/m when the majority of springs are small enough that their extension will be measured in cm or mm. Moving forwards, students will follow the provided experimental method to carry out the investigation and produce a set of results which can be used to plot the line. The two distinct sections of the line are discussed and the actual words of Hooke’s Law are given and again discussed and considered. The final part of the lesson involves the students being challenged to apply their knowledge of the law to a range of application questions and assessing against the displayed mark scheme. This lesson has been written for GCSE students but can be used with KS3 students who are studying the extension of a spring

An informative lesson presentation (24 slides), accompanied by a set of differentiated question worksheets, which together guide students through calculating energy changes in reactions and then challenges them to apply their new-found knowledge. The lesson begins by asking the students to complete a sentence which details how energy is taken in to break bonds in the reactants and given out when bonds are formed in the products. The bond energy table is then introduced so that students understand how it will be used in questions. Moving forwards, a step by step guide is used to calculate the energy change value for two reactions and students are shown how to interpret the positive or negative result as endothermic or exothermic respectively. The remainder of the lesson asks the students to apply what they have learnt to calculate the energy change for two more reactions. This question worksheet is differentiated two ways so that students who need extra assistance can still access the work. This lesson has been designed for GCSE students

A lesson presentation (44 slides), accompanied by a question worksheet, which together looks at the reactants and products of a neutralisation reaction and challenges students to represent these reactions with equations. The lesson begins with a bit of fun as students are asked to read through a scene from the US comedy show and spot that a neutralisation reaction is hidden under the jokes. Students will use their KS3 knowledge to recall that these reactions involve acids and alkalis and moving forwards they will be introduced to a new term, base. The rest of the lesson focuses on writing word and balanced symbol equations for different neutralisation reactions. A step by step guide is used to demonstrate how to work out the name of the salt as well as writing accurate chemical formulae. Finally, students are challenged to apply their new-found knowledge and complete equations for 4 neutralisation reactions and they can assess against the displayed mark schemes. Progress checks have been written into the lesson at regular intervals so that this self-assessment is constant and any misconceptions are quickly addressed. This lesson has been written for GCSE students but could be used with younger students who are looking to extend their knowledge

This is a detailed lesson resource that covers the content of point 5.1.3 (a) of the OCR A-level Biology A specification which states that students should be able to demonstrate and apply their understanding of the roles of mammalian sensory receptors. There is a particular focus on the Pacinian corpuscle to demonstrate how these receptors act as transducers by converting one form of energy into electrical energy which is then conducted as an electrical impulse along the sensory neurone. The lesson begins by looking at the different types of stimuli that can be detected. This leads into a written task where students have to form sentences to detail how thermoreceptors, rods and cones, hair cells in the inner ear and vibration receptors in the cochlea convert different forms of energy into electrical energy. Students will be introduced to the term transducer and will be challenged to work out what these cells carry out by using their sentences. As stated above, students will meet a Pacinian corpuscle and learn that this receptors detects pressure changes in the skin using the concentric rings of connective tissue in its structure. The rest of the lesson focuses on how ions are involved in the maintenance of resting potential and then depolarisation. Time is taken to look into the key details of these two processes so students are confident with this topic when met again during a lesson on the generation of action potentials. All of the tasks are differentiated to allow students of different abilities to access the work. As well as understanding checks to allow the students to assess their progress against the current topic, there are also a number of prior knowledge checks on topics like inorganic ions and methods of movement. This lesson has been designed for students studying the OCR A-level Biology course
