The topics that are tested within the lesson include: Conservation of mass and balanced symbol equations Relative formula mass Mass changes when a reactant or product is a gas Moles Amounts of substances in equations Concentration of solutions Students will be engaged through the numerous activities including quiz rounds like “Number CRAZY” and “Are you on FORM” whilst crucially being able to recognise those areas which need further attention

A fully resourced lesson which includes an informative lesson presentation (34 slides) and differentiated worksheets that show students how to convert between units so they are confident to carry out these conversions when required in Science questions. The conversions which are regularly seen at GCSE are covered as well as some more obscure ones which students have to be aware of. A number of quiz competitions are used throughout the lesson to maintain motivation and to allow the students to check their progress in an engaging way This lesson has been designed for GCSE students but is suitable for KS3

A fully-resourced lesson which looks at the meaning of the rate of reaction and guides students through calculating both the mean and instantaneous rate of reaction. The lesson includes a concise lesson presentation (19 slides) and a question worksheet which is differentiated two ways. The lesson begins by challenging the students to suggest the missing factor in the rate of reaction equation so they can learn that either the mass of a reactant or a mass of a product could be used. Links are made to practical skills as students will understand that if a product is in the gaseous form, the volume produced within a set time will enable the rate to be calculated. Worked examples are used to show the students how to calculate the mean rate of reaction and then the instantaneous using a tangent. The rest of the lesson involves collecting data from an experiment to calculate the rate of reaction. The questions associated with the practical have been differentiated so students who need assistance can still access the learning. This lesson has been written for GCSE students

A fully-resourced lesson which includes a lesson presentation (24 slides) and a worksheet which is differentiated so that students can judge their understanding of the topic of writing half equations for electrolysis and access the work accordingly. The lesson uses worked examples and helpful hints to show the students how to write half equations at both the cathode and anode. Time is taken to remind students about the rules at the electrodes when the electrolyte is in solution so that they can work out the products before writing the equations. This lesson has been designed for GCSE students (14 - 16 years old in the UK) but could be used with older students.

An engaging lesson presentation (95 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 TOPIC 4 (Chemical changes) of the AQA GCSE Chemistry specification (specification point C4.4) The topics that are tested within the lesson include: Reactivity series Extraction of metals and reduction Oxidation and reduction in terms of electrons Reactions of metals with acids Neutralisations Titrations Electrolysis Half equations Students will be engaged through the numerous activities including quiz rounds like “It’s time for ACTION” and “Number CRAZY” whilst crucially being able to recognise those areas which need further attention

A concise lesson presentation (21 slides) which uses a range of methods to allow students to discover how to draw dot and cross diagrams for covalent structures. The lesson begins by challenging the students to recall their knowledge of electronic structure to show the outer shell of two specified atoms. They will then see how it is possible for both of these atoms to get full outer shells by sharing as happens in this type of bonding. A few more examples are used to consolidate this understanding before quick competition is used to check the understanding so far. Moving forwards, a step by step guide shows students how to draw dot and cross diagrams using the same techniques as was utilised with the hulas. This lesson has been written for GCSE students but could be used with higher ability KS3 students.

This revision lesson contains a motivating and engaging powerpoint (67 slides) and associated worksheets which have been designed to challenge student knowledge of the Periodic Table. The lesson involves a wide range of activities which include exam questions with clear answers to allow students to self-assess, quiz competitions and differentiated tasks. The students will enjoy the transitions between the different activities whilst crucially being able to evaluate their understanding of this key topic in Chemistry. Deliberately, the lesson hasn’t been written for any particular exam board or exclusively for Combined Science or Chemistry, but instead it covers the topics which are shown below and this will allow teachers to pick and choose which parts they want to do in a particular lesson. Properties of the alkali metals (group I) Properties of the halogens (group VII) Properties of the noble gases (group 0) Formation of ionic compounds between group I and VII elements Reactivity of the alkali metals and the halogens Displacement reactions of the halogens The transition elements Organisation of the Periodic Table Predicting properties of the unknown or rare elements As the title suggests, the content of this lesson has been written to be GCSE standard and therefore is most suitable for use with 14 - 16 year olds. However, it could be used with younger students who are doing work on the topic and want to challenge themselves

This lesson uses 17 multiple-choice questions to challenge students to apply their understanding to the calculation sections of the course. The PowerPoint and accompanying resources are designed to act as revision during the final weeks leading up to the AQA GCSE Combined chemistry exams and the following topics are covered: Atoms and ions Isotopes Concentration of solutions Mole calculations using Avogadro’s constant Calculating relative formula mass Mole calculations using mass and relative formula mass Calculating masses in reactions Calculating energy changes in reactions Calculating the mean rate of reaction All 17 questions have answers embedded into the PowerPoint along with explanations and are followed by additional tasks to further check understanding if it was initially limited.

This lesson revisits the topic of random and systematic errors and also challenges students on other scientific skills such as identifying variables. Students tend to find this topic confusing, so the PowerPoint and accompanying resources have been designed to support them to identify whether an error is random or systematic and then to understand what to do next. The lesson guides the students through a series of real life examples and shows them how to spot each type of error. There is a considerable mathematical element to this lesson, including the calculation of means or missing values in a table. The lesson concludes with a series of exam-style questions where the students have to apply their understanding of identifying errors, variables and calculating means.

A concise lesson presentation (20 slides) that looks at how the collision theory is related to the rate of reaction. This is a short lesson that would be taught at the beginning of the topic that looks at the rate of reaction and the factors that affect the rate. Students are challenged with a quick competition that gets them to recognise keywords which are involved in the collision theory. Some time is then taken to focus on "activation energy" and how this is shown on a reaction profile. Finally, students will use their keywords to form a clear definition for the collision theory which includes its link to the rate of reaction so this can be used in the upcoming lessons This lesson has ultimately been designed for GCSE students but can be used with all age groups as an introduction to the topic

A concise lesson presentation (19 slides) which looks at meaning of the key term, polymers, and briefly explores addition and condensation polymers. The lesson begins with a fun exercise to enable students to come up with the word polymers so that they can be introduced to the definition and then relate this to another term, monomers. A quiz competition is used to introduce addition and condensation polymers. Students are shown the displayed formulae and names of a few addition polymers and then challenged to use this to name and draw some others. They will then learn how DNA is an example of a condensation polymer. A set homework is included in the lesson which gets students to research thermosetting and thermosoftening polymers
