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

An engaging, practical-based lesson presentation (34 slides), accompanied by an assistance sheet, which together look at how the results of displacement reactions can be used to order the metals into the reactivity series. The lesson begins by introducing a displacement reaction and ensuring that students understand the meaning of this term and how it relates to the topic of the lesson. Students will carry out a series of 12 displacement reactions, involving 4 different metals and will then be challenged to interpret the results to place the metals into their allocated positions in the series. Moving forwards, the students are given the results of more reactions, some which occurred and others which didn’t so they can place the remaining metals into the reactivity series. Time is also taken to understand how the position of hydrogen in the series can be used to predict the results of reactions between metals and acids. This lesson has been written for GCSE students but could be used with higher ability KS3 students

A concise lesson presentation (27 slides) that looks at the key details of the sub-atomic particles and briefly explores how the atomic and mass numbers of the Periodic Table can be used to calculate the numbers of these particles in different atoms. The lesson begins with a Mathematical link as students are challenged to convert the size of an atom from standard form into a real number. Moving forwards, students will meet the three sub-atomic particles and be asked to predict which one is positive, neutral and negative in charge. The relative mass of a proton is shown and then students are asked to work out the mass of a neutron and an electron by observing some experimental results with a scales. Finally, the students are shown how to use the atomic number to work out the number of protons (and electrons) in an atom and how to work out the number of neutrons. This lesson has been designed to act as a knowledge recall and top-up as this should have already been learnt at KS3.

A fully-resourced lesson that explores how resistance, current and potential difference differ between series and parallel circuits. This knowledge needs to be sound in order for students to be able to carry out circuit calculations. The lesson includes a practical and task-based lesson presentation (24 slides) and an accompanying worksheet. The lesson begins by challenging the students to recognise the key difference between the two circuits, in that in a parallel circuits, the electrons can follow more than one route. Moving forwards, each physical factor is investigated in each type of circuits and students carry out tasks or calculations to back up any theory given. Helpful analogies and hints are provided to guide the students through this topic which is sometimes poorly understood. Students will be challenged to use the V = IR equation on a number of occasions so that they are comfortable to find out any of these three factors. Progress checks have been written into the lesson at regular intervals so that students are constantly assessing their understanding and any misconceptions can be addressed. This has been written for GCSE students, but could be potentially used with higher ability KS3 students.

A fast-paced lesson that explores the meaning of “health” and introduces the idea of communicable and non-communicable diseases. The lesson begins by showing the students an example of a health survey so they can complete a definition of the meaning of this term. Despite being widely used in the English language, the actual Scientific definition is not always well known by students so this 1st task is an important one. Moving forwards, students are given 5 minutes to see if they can fill an A-Z with the names of different diseases. Students will learn that diseases can be grouped as communicable or non-communicable and will be encouraged to discuss what the determining factor is on this classification. A quiz competition called “TO COM or NOT TO COM” is a play on words of Shakespeare’s famous saying but acts to test whether the students can distinguish a number of diseases as being spread by pathogens or not. After each disease is revealed, time is taken to look at the details of some of them like cystic fibrosis and the zika virus. The lesson concludes with the example of the human-papilloma virus and the connection between this and cervical cancer so that students can recognise that sometimes both types of disease are involved. This lesson has been written for GCSE students (14 - 16 year olds in the UK) but could be used with younger students who are looking at the healthy living topic.

This concise lesson presentation (20 slides) guides students through the effect of changing pressure on the position of the equilibrium. The key skill to this topic involves recalling the rule of increasing pressure and being able to recognise how many moles are on each side of the reaction. For this reason, time is taken to remind the students of the meaning of the mole numbers in a reaction and working through an example together so they can see which side will be favoured. The final part of the lesson involves a game called “The PRESSURE is on” where students are in a race against the clock to balance an equation and then work out which way the equilibrium will shift when either the pressure is increased or decreased. This lesson has been written for GCSE students.

A fast-paced, quick lesson which focuses on the key terminology that is involved in the separation topic so that students are confident with the definitions and to use them in context. A lot of the key terms begin with the prefix SOL and the opening task challenges students to use their Chemistry knowledge to convert numbers to letters to come up with these three letters. Having completed the crossword with the 5 key terms, solute, solution, solubility, solvent and soluble, students have to match the crossword clues with each term. Moving forwards, students are introduced to the term, saturated, and briefly shown the meaning of this word. The final task of the lesson challenges the students to use each of the 6 terms beginning with S to complete a passage about salt dissolving in a water.

This lesson uses the example of the genetic engineering of bacteria to produce insulin to walk students through the steps involved in this process. It has been written for GCSE students and therefore includes the detail required at this level, such as the involvement of restriction enzymes and the sticky ends that their cut produces. The lesson begins by challenging students to recognise that insulin is being described by a series of clues. Some further details of this hormone are recalled to test their previous knowledge of the endocrine system and also to lead into the genetic engineering of bacteria to make this protein. Moving forwards, time is taken to go through the details of plasmids and how they act as vectors as well as the enzymes, restriction and ligase. The main task of the lesson uses a series of descriptions to go through the steps involved in the process. Words or phrases are missing from each description so students have to use the terms they’ve encountered in this lesson as well as their prior knowledge to complete the step. Discussion-provoking questions are added to encourage the students to consider why certain parts of the process occur. The lesson concludes by the consideration of other organisms which have been genetically engineered as well as some of the risks of the process, which students are asked to complete for homework. As detailed above, this lesson has been designed for GCSE students but could be used with students taking A-level Biology, who are struggling to understand the detail found at this level and need to revisit the foundations.

This lesson focuses on the nature of the genetic code in terms of being near universal, non-overlapping and degenerate and specifically focuses on this latter term to explain how a mutation may not result in a change to the sequence of amino acids. The PowerPoint has been designed to cover point 2.1.3 (f) of the OCR A-level Biology A specification and there are clear links to gene mutations which students will meet in module 6. The lesson begins by introducing the terms near universal and non-overlapping in addition to degenerate. A quick quiz competition is used to generate the number 20 so that the students can learn that there are 20 proteinogenic amino acids in the genetic code. This leads into a challenge, where they have to use their prior knowledge of DNA to calculate the number of different DNA triplets (64) and the mismatch in number is then discussed and related back to the lesson topic. Moving forwards, base substitutions and base deletions are briefly introduced so that they can see how although one substitution can change the primary structure, another will change the codon but not the encoded amino acid. The lesson concludes with a brief look at the non-overlapping nature of the code so that the impact of a base deletion (or insertion) can be understood when covered in greater detail in module 6.

This engaging lesson looks at the role of haemoglobin in transporting oxygen and carbon dioxide and compares the dissociation curves for foetal and adult haemoglobin. The detailed PowerPoint has been designed to cover points 3.1.2 (i & j) of the OCR A-level Biology A specification and includes references to the role of carbonic anhydrase and the formation of haemoglobinic acid and carbaminohaemoglobin. The lesson begins with a version of the quiz show Pointless to introduce haemotology as the study of the blood conditions. Students are told that haemoglobin has a quaternary structure and are challenged to use their prior knowledge of biological molecules to determine what this means for the protein. They will learn that each of the 4 polypeptide chains contains a haem group with an iron ion attached and that it is this group which has a high affinity for oxygen. Time is taken to discuss how this protein must be able to load (and unload) oxygen as well as transport the molecules to the respiring tissues. Students will plot the oxyhaemoglobin dissociation curve and the S-shaped curve is used to encourage discussions about the ease with which haemoglobin loads each molecule. At this point, foetal haemoglobin and its differing affinity of oxygen is introduced and students are challenged to predict whether this affinity will be higher or lower than adult haemoglobin and to represent this on their dissociation curve. The remainder of the lesson looks at the different ways that carbon dioxide is transported around the body that involve haemoglobin. Time is taken to look at the dissociation of carbonic acid into hydrogen ions so that students can understand how this will affect the affinity of haemoglobin for oxygen in an upcoming lesson on the Bohr effect. It is estimated that it will take in excess of 2 hours of A-level teaching time to cover the detail of these two specification points as covered in this lesson

This is a fully-resourced lesson that looks at the reflection of light waves and uses a series of practical based tasks to discover the rules of reflection as well as introducing the critical angle. In addition, students will encounter how total internal reflection can be used in medicine in endoscopy and will be challenged to carry out a task where they act as a doctor to explain to a patient how the procedure works. The lesson contains a variety of tasks, progress checks to check on understanding and a few quick competitions, which introduce key terms. For example, the cover image shows one of these competitions called REFLECT THE WORD where students have to work out the key term - the normal in this case. The understanding of key terminology such as the normal is important so that students can construct ray diagrams in this lesson and in associated topics such as refraction. This lesson has been designed for GCSE aged students but could be used with younger students who are looking to go into this topic in greater depth than perhaps would normally be encountered at their level

This is a detailed lesson which looks at the topic of reaction times and guides students through calculating a reaction time using the results of the well known ruler-drop test. In addition, students will see how reaction times can be applied in athletics but also in the calculation of the thinking distance for drivers. The lesson includes an engaging lesson presentation (32 slides) and a student task worksheet. The lesson begins by introducing the key term, reaction time, and teaching students that the average reaction time is 0.2 seconds. Moving forwards, a step by step guide is used to show the students how to take the value for distance travelled by a ruler in the drop test and use the equations of motion and change in velocity equation to calculate the reaction time. There is a large mathematical element to the lesson which challenges the students ability to rearrange formula, convert between units and leave answers to a specified number of significant figures. The answers and methods in obtaining these are always displayed at the end of each task so that the students can assess their understanding and recognise where errors were made if any were. Students will have to follow the provided method to obtain 5 results in the ruler drop test and ultimately find out their own reaction time. The remainder of the lesson looks at how the thinking distance at different speeds can be calculated. This lesson has been written for GCSE students due to the high maths content but could be used with younger students of high ability.
