This is an informative and engaging lesson, which has been designed for GCSE but is perfectly suitable for younger students who are studying the states of matter. Students will have encountered this topic at KS3 and potentially before, and therefore the aim of this lesson is to consolidate that knowledge and to deepen in critical areas. A number of quick competitions have been written into the lesson to maintain engagement and to test prior knowledge in a different way. In addition, progress checks are found at regular intervals so that students can constantly assess their understanding. The start of the lesson looks at the different properties of the three states and ensures that particle diagrams are not only recognised but can be explained. A lot of students consider elements to be in one state only at all times and therefore time is taken to show them how the specific temperature is the determining factor on the state. Students are guided through using the melting and boiling points to determine which state a substance is in at a given temperature. The rest of the lesson focuses on changing state and the change in the particles at each of these stages.

This is a concise, fast-paced lesson which guides students through the critical skills needed to calculate the atom economy of a chemical reaction. It has been designed for GCSE students and focuses on the calculation as well as interpreting the final value. In order to calculate the mass of the desired product and other products, students have to be able to calculate the relative formula mass - therefore time is taken to revisit these skills and worked examples are used with this and the actual calculations to enable the students to visualise how they should set their work out. The lesson finishes with some progress check questions where students are challenged to state which of four chemical reactions has the highest atom economy. This lesson could be taught in combination with the percentage yield topic and an accompanying lesson on that calculation is available on this site.

Alongside the “properties of waves” lesson, this lesson is also designed to be fast-paced with a focus on the key terminology of the waves topic as well as looking at the different calculations that can be carried out. It is written for GCSE students and challenges their mathematical skills throughout, by asking them to rearrange formulae, convert units and write in standard form. The lesson begins by recalling the definitions for wavelength, frequency and wave velocity and then introducing them to the equation that links them. The velocity of sound waves in three mediums is the initial focus, so that students can recognise that the velocity is higher in liquids and solids than in air. Moving forwards, the concept of an echo is discussed and again a calculation used to show them how distance could be worked out with the added extra of the final division by 2. There are progress checks such as these written throughout the lesson so that students have the opportunity to assess their understanding. A number of quick competitions are also included, in order to maintain engagement whilst check understanding in a different form.

An engaging lesson presentation (32 slides) and differentiated worksheets that look at the meaning of the substances termed monoclonal antibodies, explains how they are produced and explores their different applications. The lesson begins by breaking the term down into three parts so that students can understand that these substances are proteins that attach to antigens and come from a single clone of cells. Students will meet key terms such as lymphocytes, myelomas and hybridomas and will be able to link them to understand how these antibodies are produced. Moving forwards, time is taken to focus on the application of monoclonal antibodies in pregnancy tests. There are regular progress checks throughout the lesson so that students can assess their understanding and a set homework is included as part of the lesson. This lesson has been written for GCSE students but can be used with lower ability A-level students who are studying this topic

This is a detailed, engaging and fully-resourced REVISION LESSON which allows students of all abilities to assess their understanding of the content in module 2.1.3 (Nucleotides and nucleic acids) of the OCR A-level Biology A specification. Considerable time has been taken to design the lesson to include a wide range of activities to motivate the students whilst they evaluate their knowledge of DNA, RNA and the roles of these nucleic acids in DNA replication and protein synthesis. Most of the tasks have been differentiated so that students of differing abilities can access the work and move forward as a result of the tasks at hand. This lesson has been planned to cover as much of the specification as possible but the following sub-topics have received particular attention: The structure of DNA Phosphorylated nucleotides DNA replication Transcription and translation Gene mutations and their affect on the primary structure of a polypeptide The structure of RNA In addition to a focus on the current topic, links are made throughout the lesson to other topics such as the journey of an extracellular protein following translation and the cell cycle. If you like the quality of this revision lesson, please look at the other uploaded revision lessons for this module and for this specification

An engaging lesson presentation (54 slides) that uses a variety of exam questions, quick tasks and competitions to allow students to assess their understanding of the different topics within Module B5 of the Combined Science specification. All of the exam questions have displayed answers and some are differentiated to allow for the differing abilities. The students will enjoy the competitions which include "Take the HOTSEAT" and "This shouldn't be too TAXING" whilst recognising those areas which require further attention.

This engaging lesson presentation (48 slides) and associated worksheets uses exam questions with displayed mark schemes, quick tasks and quiz competitions to enable students to assess their understanding of the topics found within module B4 of the OCR Gateway A Combined Science specification. The topics which are specifically tested within the lesson include: Ecosystems, Competition and interdependence, The carbon cycle and Decomposers Students will enjoy the competitions such as "Number CRAZY" and "Take the HOTSEAT" whilst crucially being able to recognise those areas which need their further attention

An engaging lesson presentation (49 slides) and associated worksheets that uses a combination of exam questions, quick tasks and quiz competitions to help the students to assess their understanding of the topics found within unit C5 (Monitoring and controlling chemical reactions) of the OCR Gateway A GCSE Combined Science specification. The topics that are tested within the lesson include: Concentration of solution Rate of reaction Factors affecting the rate of reaction Reversible reactions Equilibrium position Students will be engaged through the numerous activities including quiz rounds like “Under PRESSURE” and “Number CRAZY” whilst crucially being able to recognise those areas which need further attention

A fully-resourced lesson which guides students through using genetic trees to work out the genotypes of unknown individuals and also how to work out whether a condition is caused by a dominant or a recessive allele. This lesson includes a detailed lesson presentation (24 slides) and a series of differentiated questions to allow the students to try to apply their new-found knowledge. The lesson begins by challenging students to recall the meaning of the key terms, genotype and phenotype. Time is taken initially to explain how genetic trees can be used in questions. Lots of useful hints are given throughout the lesson, such as filling in the genotypes for those that you already know like the affected in a recessive condition. Moving forwards, a worked example is used to talk the students through a question. Students are then given the opportunity to try a question and this has been differentiated so those who need extra assistance can still access the work. The remainder of the lesson shows the students how they can use the tree to work out whether the condition is caused by a dominant or recessive allele and again a progress check is used so students can assess their understanding. This lesson has been designed for both GCSE and A-level students.

A concise, engaging lesson presentation (22 slides) which looks at the different responses of the body as a result of adrenaline release. In line with the actions of adrenaline, the lesson begins with a range of quiz competitions to introduce key terms and responses to the students. Once the students know that it causes both the breathing and heart rate to increase, they are challenged to complete a passage which brings this information together to explain how the increased respiration rate is related to the fight or flight tag line. Moving forwards, students will be introduced to the meaning of the term vasodilation and then asked to consider which organs will need extra blood flow during times of stress and conversely, which tissues can have blood directed away from them. The lesson finishes by looking at how a negative feedback loop is used as the final control to ensure that energy resources are not wasted during times when there is no stress.

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.

A fully-resourced lesson that looks at the reaction of an acid with a metal or a metal carbonate and guides students through writing word and symbol equations to represent these reactions. This lesson includes a lesson presentation (39 slides) and differentiated worksheets. The lesson begins by challenging the students to spot a pattern when naming the salts that are produced from these reactions. Students are shown how the second word of the salt’s name depends upon the particular acid involved in the reaction and are given opportunities to watch this in worked examples before applying their knowledge to a question. Students will also meet the general formula for the reaction of an acid with a metal carbonate. Moving forwards, a step by step guide is used to show the students how to write fully balanced symbol equations. Time is taken to specifically show them how to write accurate chemical formulae, including those which involve a bracket as is common in this topic. The final task challenges the students to bring all of this information together to write word and symbol equations for three reactions. This worksheet is differentiated two ways so students who require some assistance can still access the work. This lesson has been written for GCSE students (14 - 16 year olds in the UK)

An engaging lesson presentation (31 slides) and associated worksheet that looks at animal and plant cells as eukaryotic cells. The lesson focuses on the organelles which are found inside these two cells and ensures that students understand the difference between the cells as well as briefly looking at the difference to prokaryotic cells at the end of the lesson. There is a lot of key terminology involved in this topic, so a range of tasks including fun quiz competitions are used to introduce these terms in an engaging manner. The lesson is student based, with the emphasis on them to identify the functions of the different organelles as well as recognising which ones are found in both cells or just plant cells. Discussions are encouraged during the lesson with leading questions, such as questioning whether a red blood cell isn’t actually an eukaryotic cell because of the lack of nucleus. Progress checks have been written into the lesson at regular intervals during the lesson so that students can assess their understanding. This lesson has been written for GCSE students but could be used with KS3 students who are looking to extend their knowledge beyond the basics that they will be taught at this level.

A quick, concise lesson presentation (15 slides) which together with a question worksheet focuses on ensuring that students can define an isotope and pick these substances out from a selection of substances. The lesson begins by looking at the number of sub-atomic particles in an aluminium atom so that students can recall what is shown by the atomic and mass numbers. This will enable students to calculate the number of protons, neutrons and electrons in three given isotopes and as a result, complete a definition of these substances. The remainder of this short lesson involves 4 application questions where students either have to recognise isotopes from a table or from a diagram and also are asked to write out the formula of an isotope. Ideally this lesson will be taught in conjunction with a lesson on atomic structure.
