An engaging lesson presentation (80 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 3 (Quantitative chemistry) of the AQA GCSE Chemistry specification (specification point C4.3). The lesson includes useful hints and tips to encourage success in assessments. For example, students are shown how to recognise whether to use Avogadro’s constant or the moles formula in a moles calculation question. 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 Atom economy Molar volume Students will be engaged through the numerous activities including quiz rounds like “Number CRAZY” and “In the BALANCE” whilst crucially being able to recognise those areas which need further attention

This is a fully-resourced lesson that looks at how the transfer of electrons from metals to non-metals causes ionic bonds and compounds to form and then explores the different properties of these structures. The lesson includes a detailed and engaging lesson presentation (43 slides) and a task worksheet which has been differentiated two ways. The lesson begins by introducing the name of the type of bond, but does not go into any more detail at this stage. This is because the lesson is designed to allow the students to discover that in order for both of the atoms involved to get a full outer shell, electrons have to be transferred from one to the other. Over the course of the lesson, students will recognise that it is the metal that loses the electrons and becomes a positive ion whilst the non-metal gains the electrons and becomes a negative ion. There are lots of discussion and discovery points like this written into the lesson so that students can take ownership for their learning. Students are guided through drawing dot and cross diagrams to represent these compounds and as a result links are made to the topics of naming compounds, writing chemical formulae, forming ions and electron configurations. There are a number of quick competitions in the lesson which introduce new terms to the students. One such competition introduces the term lattice and the lesson builds from here to understand why ionic compounds have high melting and boiling points. Moving forwards, students will also learn that solid ionic compounds cannot conduct electricity whilst those in molten form or in an aqueous solution are able to. The final task of the lesson challenges the students to bring all of the information together they have seen to draw a dot and cross diagram for aluminium oxide, explain how it was formed and then explain how aluminium is extracted from this compound by electrolysis. This final task has been differentiated so that students who need extra assistance can still access the learning. This lesson has been written for GCSE aged students but could be used with higher ability younger students who are pushing on with the elements, compounds and mixtures topic

This is a fully-resourced lesson about group 7 of the Periodic Table, the halogens, which includes a lesson presentation (34 slides) and a differentiated worksheet. The lesson begins by challenging students to recognise and explain why the electronic structure of group 1 and group 7 means that they react together easily. As the lesson progresses, students will learn more and more properties about the halogens and key terms such as diatomic are used throughout so that students become accustomed to these. Moving forwards, students will carry out a series of displacement reactions so that they can recognise that the reactivity of these elements decreases as they go down the group. Students are challeged to explain this with reference to electron configuration and a differentiated worksheet will help those who need assistance to access this work. This lesson has been designed for GCSE students (14 - 16 year olds in the UK) but is suitable for younger students who might be carrying out a project on the Periodic Table

A fully-resourced lesson which prepares students for the range of mathematical-based questions that they could encounter on the two AQA GCSE Chemistry papers. The lesson contains a wide range of activities which include exam-style questions with markschemes embedded within the PowerPoint to enable the students to assess their current understanding. There are also 8 quiz competition rounds interspersed throughout the lesson to maintain engagement and motivation. The mathematical skills covered in this lesson include: Calculating the number of sub-atomic particles in atoms and ions Writing chemical formulae for ionic compounds Identifying isotopes Using Avogadro’s constant to calculate the number of particles Calculating the relative formula mass Calculating amount in moles using the mass and the relative formula mass Balancing chemical symbol equations Calculating reacting masses Gas calculations using molar volume Calculating the concentration of an unknown solution Calculating the atom economy and percentage yield Calculating energy changes in reactions Temperature and pressure and the position of equilibrium Most of the resources have been differentiated two ways to allow students of differing abilities to access the work whilst still being challenged. In addition, step by step guides are used to demonstrate how to carry out some of the more difficult calculations such as the harder mole calculations and calculating masses in reactions

This lesson explains the law of conservation of mass and applies this law to a closed system and a non-enclosed system. The PowerPoint and accompanying resources have been designed to cover point 1.48 of the Edexcel GCSE Chemistry specification and also covers that point in the Chemistry section of the Combined Science course. The lesson begins by introducing the law of the conservation of mass. Students will learn that they can expect questions which challenge them to prove that mass is conserved through the use of the relative formula mass. Therefore, the next section of the lesson focuses on the skills associated with this calculation and looks at more different formulae such as those with brackets. Students are given an opportunity to check their skills before trying to prove mass is conserved in three chemical reactions. All questions have displayed mark schemes so that students can assess their understanding. The rest of the lesson looks at instances of when the mass of the reactants does not equal the mass of the products. A practical method for the decomposition of copper carbonate is provided if the teacher wants to use it, so that students can collect results which show this difference in mass. Discussions are encouraged in order to get students to offer explanations as to why the mass of the products is lower. Once the gas has been identified, students are further challenged to consider apparatus that could be used to collect and record the results to again prove conservation

This is a fully-resourced lesson that looks at the different skills needed to calculate the percentage yield. This lesson has been designed for GCSE students and includes an engaging lesson presentation and a skills check worksheet. As well as the obvious Science involved in the lesson, the students’ mathematical skills are challenged as they have to rearrange formulae and also there is a literacy element as recognition of the different types of yield is important. The percentage yield formula is broken down into the two elements of theoretical yield and actual yield and a step by step guide through worked examples is used to visualise how these calculations should be tackled. Students are given regular opportunities to test the skills which they have just learnt (or recalled) before bringing them together to calculate the percentage yield. The lesson finishes with a difficult question which challenges the students to rearrange the formula to make theoretical yield the subject.

This lesson explains how ionic bonds are formed to form ions and describes the structure of an ionic compound. The engaging lesson PowerPoint and accompanying resources have been designed to cover points 1.21 and 1.27 of the Edexcel GCSE Chemistry specification and this also covers those points on the Combined Science specification. The lesson begins by introducing the name of the type of bond, but does not go into any more detail at this stage. This is because the lesson is designed to allow the students to discover that in order for both of the atoms involved to get a full outer shell, electrons have to be transferred from one to the other.

This is a fully-resourced lesson which uses exam-style questions, engaging quiz competitions, quick tasks and discussion points to challenge students on their understanding of topics C1 & C6 - C8, that will assessed on PAPER 4. It has been specifically designed for students on the Edexcel GCSE Combined Science course who will be taking the FOUNDATION TIER examinations but is also suitable for students taking the higher tier who need to ensure that the key ideas are known and understood. The lesson has been written to cover as many specification points as possible but the following sub-topics have been given particular attention: Hydrocarbons The homologous series of alkanes Empirical formula Covalent dot and cross diagrams Fractional distillation of crude oil The properties of the different fractions The complete combustion of a hydrocarbon Changes in the carbon dioxide levels in the atmosphere Deforestation Changes in the Earth’s atmosphere Polluting gases The formation of acid rain Detecting oxygen and chlorine The properties of the halogens Metals vs non-metals The reaction of alkali metals with water Explaining the pattern of reactivity of the alkali metals The collision theory Endothermic and exothermic reactions In order to maintain challenge whilst ensuring that all abilities can access the questions, the majority of the tasks have been differentiated and students can ask for extra support when they are unable to begin a question. Step-by-step guides have also been written into the lesson to walk students through some of the more difficult concepts such as the changes in the Earth’s atmosphere and explaining the reactivity of the alkali metals in terms of electronic configurations. Due to the extensiveness of this revision lesson, it is estimated that it will take in excess of 3 teaching hours to complete the tasks and therefore this can be used at different points throughout the duration of the course as well as acting as a final revision before the PAPER 4 exam.

This is a fully-resourced lesson which is designed for GCSE students and explores the topic of compounds, specifically focusing on naming these chemicals based upon the elements within them and from their chemical formula. The lesson includes an engaging lesson presentation (46 slides) and a worksheet containing three tasks for the lesson. The lesson begins with some simple multiple choice questions to check that students can spot the chemical symbol and definition of an element, but more importantly pick out the formula for a compound. Time is taken to go through the explanation of why substances are elements or compounds and specific examples given. A quick understanding check, in the form of a competition called “To COM or NOT TO COM”,is used to check that students can identify elements or compounds from a name or given formula. The remainder of the lesson focuses on naming compounds. Students are challenged to spot a pattern when presented with the names of two compounds, which contain 2 elements only. For both compounds that contain 2 elements or 3 or more, the rules to naming are introduced before examples are shown so that students can visualise how to construct their answer. They are then given an opportunity to apply this to a number of questions in the set tasks. The last part of the lesson moves this forward by looking at how these same rules can be applied when the chemical formula of a compound is given and this is related to another topic as they are challenged to write a word equation containing a range of compounds when presented with the symbol equation. Progress checks are written into the lesson at regular intervals so that students can constantly assess their understanding. Although this is written for GCSE students, it is perfectly suitable for use with younger students who are learning about elements, compounds and mixtures and the teacher wants to push them along.
