This is an engaging revision lesson which uses a range of exam questions, understanding checks, quick tasks and quiz competitions to enable students to assess their understanding of the content within topic 8 (Fuels and Earth Science) of the Edexcel GCSE Chemistry specification. The specification points that are covered in this revision lesson include: Recall that hydrocarbons are compounds that contain carbon and hydrogen only Describe and explain the separation of crude oil into simpler, more useful mixtures by the process of fractional distillation Recall the names and uses of the fractions Explain how hydrocarbons in different fractions differ from each other Describe the complete combustion of hydrocarbon fuels as a reaction Explain why the incomplete combustion of hydrocarbons can produce carbon and carbon monoxide Explain how carbon monoxide behaves as a toxic gas Explain how impurities in some hydrocarbon fuels result in the production of sulfur dioxide Explain some problems associated with acid rain caused when sulfur dioxide dissolves in rain water Explain why, when fuels are burned in engines, oxygen and nitrogen can react together at high temperatures to produce oxides of nitrogen, which are pollutants Evaluate the advantages and disadvantages of using hydrogen, rather than petrol, as a fuel in cars Explain how cracking involves the breaking down of larger, saturated hydrocarbon molecules (alkanes) into smaller, more useful ones, some of which are unsaturated (alkenes) The students will thoroughly enjoy the range of activities, which includes a quiz competition called “POLLUTE THE AIR…WITH THE ANSWER” where they have to compete to be the 1st to recognise a pollutant gas from a series of clues whilst crucially being able to recognise the areas of this topic which need their further attention. This lesson can be used as revision resource at the end of the topic or in the lead up to mocks or the actual GCSE exams

This is an engaging revision lesson which uses a range of exam questions, understanding checks, differentiated tasks and quiz competitions to enable students to assess their understanding of the content within topic 1 (Key concepts in Chemistry) of the Edexcel GCSE Chemistry specification. Topic 1 is assessed in both papers 1 and 2, and therefore this lesson has been written in the detail that means it is likely to be used over the course of a number of lessons. The specification points that are covered in this revision lesson include: ATOMIC STRUCTURE Explain why atoms contain equal numbers of protons and electrons Recall the meaning of the term mass number of an atom Describe atoms of a given element as having the same number of protons in the nucleus and that this number is unique to that element Describe isotopes as different atoms of the same element containing the same number of protons but different numbers of neutrons in their nuclei Calculate the numbers of protons, neutrons and electrons in atoms given the atomic number and mass number Calculate the relative atomic mass of an element from the relative masses and abundances of its isotopes IONIC BONDING Explain how ionic bonds are formed by the transfer of electrons between atoms Recall that an ion is an atom or group of atoms with a positive or negative charge Calculate the numbers of protons, neutrons and electrons in simple ions given the atomic number and mass number Explain the formation of ions in ionic compounds from their atoms, limited to compounds of elements in groups 1, 2, 6 and 7 Deduce the formulae of ionic compounds (including oxides, hydroxides, halides, nitrates, carbonates and sulfates) given the formulae of the constituent ions COVALENT BONDING Explain how a covalent bond is formed when a pair of electrons is shared between two atoms Explain the formation of simple molecular, covalent substances, using dot and cross diagrams TYPES OF SUBSTANCE Explain the properties of typical covalent, simple molecular compounds Recall that graphite and diamond are different forms of carbon and that they are examples of giant covalent substances Describe the structures of graphite and diamond Explain the properties of metals, including malleability and the ability to conduct electricity CALCULATIONS INVOLVING MASSES Calculate relative formula mass given relative atomic masses Calculate masses of reactants and products from balanced equations, given the mass of one substance The students will thoroughly enjoy the range of activities, which includes a quiz competition called “POLLUTE THE AIR…WITH THE ANSWER” where they have to compete to be the 1st to recognise a pollutant gas from a series of clues whilst crucially being able to recognise the areas of this topic which need their further attention. This lesson can be used as revision resource at the end of the topic or in the lead up to mocks or the actual GCSE exams

This is an engaging lesson that looks at a range of condensation polymers that are formed by condensation reactions. The lesson includes a detailed lesson presentation (51 slides) and accompanying worksheets which contain a differentiated task. The lesson begins by providing the students with a definition of a condensation reaction and challenging them to predict the identity of the smaller molecule. Moving forwards, students will learn that as well as water being a product, the larger molecule is known as a condensation polymer. Time is taken to look at a range of condensation polymers throughout the course of the lesson, and this includes both natural and artificial examples. Students are shown how to draw block diagrams to visualise how the functional groups react and then once water is removed, they are able to see the group that remains and joins the parts together. Students are shown how to name the ester formed according to the carboxylic acid and alcohol involved. The final part of the lesson involves a summary quiz called “It’s time to take the POLYGRAPH” where they have to read a number of passages about condensation polymers and decide which ones are telling lies and which are the truth. This lesson has been written for GCSE 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 REVISION resource has been designed to motivate and engage students whilst they are challenged on their knowledge of the content in topics C1-C5 of the AQA GCSE Chemistry specification which can be assessed on PAPER 1. This is fully-resourced and contains a detailed PowerPoint (208 slides) and accompanying worksheets, some of which have been differentiated. The resource was written with the aim of covering as many of the sub-topics in C1-C5 as possible, but the following ones have been given a particular focus: The chemical properties of the Group 1, 7 and 0 elements The structure of atoms and ions The properties of ionic compounds Drawing dot and cross diagrams to represent ionic compounds Extracting metals using carbon REDOX reactions Electrolysis of molten salts and solutions Neutralisation reactions Writing balanced chemical symbol equations Simple and giant covalent structures Diamond and graphite Calculating the relative formula mass Moles and Avogadro’s constant Calculating the mass in reactions Molar volume (Gas calculations) Concentration of solutions The organisation of the Periodic Table Due to the extensiveness of this resource, it is likely to be used over the course of a number of lessons with a particular class and this allows the teacher to focus in on any sub-topics which are identified as needing more time.

This revision resource includes exam questions, understanding checks and quiz competitions, all of which have been designed to motivate and engage the students whilst they assess their understanding of the content found in topic 2 (Experimental techniques) of the CIE IGCSE Chemistry specification for examination in June and November 2020 and 2021. This revision resource contains an engaging PowerPoint (50 slides) and associated worksheets, some of which have been differentiated to help and challenge differing abilities. The range of activities have been designed to cover as much of the Core and Supplement content as possible but the following sub-topics have been given particular attention: Identify substances and assess purity from melting and boiling point data Describe and explain the method of distillation Understand how fractional distillation separates mixtures according to their boiling points Describe and explain the method of crystallisation Demonstrate knowledge and understanding of paper chromatography Interpret simple chromatograms, including the calculation of the Rf values In addition, topics from other modules such as states of matter at different temperatures are covered so that students can see the importance of being able to make connections and links between Chemistry topics.

This revision resource contains an engaging and informative PowerPoint (55 slides) and differentiated worksheets that will enable the students to assess their understanding of the topic C9 content of the CIE IGCSE Combined Science specification for examination in June and November 2020 and 2021. The range of exam questions (with explained answers), quick tasks and quiz competitions have been designed to cover as much content as possible but the following topics have received particular attention: • The properties of the alkali metals, halogens and noble gases • Explaining the reactivity of these groups in terms of electron configurations • The transition elements • The arrangement of the Periodic Table • Predicting properties of the undiscovered elements The question sheet about the properties of the different groups has been differentiated three ways so that a range of abilities can access the work

This revision resource contains an engaging and detailed PowerPoint (66 slides) and associated worksheets, all of which are differentiated to allow students of different abilities to access the work. The range of activities that include exam questions with explained answers and quiz competitions covers the content within topic 11 (Air and water) of the CIE IGCSE Chemistry specification for examination in June and November 2020 and 2021. The resource was written to cover as much of the content as possible but the following topics have received particular attention: The fractional distillation of air to separate oxygen and nitrogen The composition of clean air The variety of reactions that form carbon dioxide The changes in the atmospheric levels of carbon dioxide and the link to global warming The common pollutants and their effects on health and buildings The treatment of water to make it safe The chemical tests for water The conditions needed for the Haber Process Efforts have been made during the design of this lesson to make connections between topic 11 and the other topics in order to show students how important it is to make Biological links. In addition, there is a big emphasis on mathematical skills and guidance is given throughout to break down any barriers that students may have with these types of questions.
