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 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 3 (Chemical changes) of the Edexcel GCSE Chemistry specification. The specification points that are covered in this revision lesson include: Recall that acids in solution are sources of hydrogen ions and alkalis in solution are sources of hydroxide ions Recall that the higher the concentration of hydrogen ions in an acidic solution, the lower the pH; and the higher the concentration of hydroxide ions in an alkaline solution, the higher the pH Recall that as hydrogen ion concentration in a solution increases by a factor of 10, the pH of the solution decreases by 1 Recall that a base is any substance that reacts with an acid to form a salt and water only Recall that alkalis are soluble bases Explain the general reactions of aqueous solutions of acids with metals, metal oxides, metal hydroxides and metal carbonates to produce salts Describe the chemical test for hydrogen and carbon dioxide Describe a neutralisation reaction as a reaction between an acid and a base Explain an acid-alkali neutralisation as a reaction in which hydrogen ions (H+) from the acid react with hydroxide ions (OH–) from the alkali to form water Explain how a soluble salts is prepared from an acid and an insoluble reactant Explain how soluble salts are prepared from an acid and a soluble reactant Recall that electrolytes are ionic compounds in the molten state or dissolved in water Explain the movement of ions during electrolysis Explain the formation of the products in electrolysis Write half equations for reactions occurring at the anode and cathode in electrolysis Explain oxidation and reduction in terms of loss or gain of electrons The students will thoroughly enjoy the range of activities, which includes quiz competitions like “From NUMBERS 2 LETTERS” where they compete to be the 1st to get the abbreviation Oil Rig 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 fully-resourced lesson describes how to calculate the concentration of solution in grams per decimetres cubed and mol per decimetre cubed. The lesson PowerPoint and accompanying questions which are differentiated have been designed to cover points 1.49 & 5.8 of the Edexcel GCSE Chemistry specification. The lesson begins by introducing students to volumes in decimetres cubed and time is taken to ensure that students are able to convert to this measurement from volumes in centimetres cubed. Moving forwards, students are shown how to calculate the concentration in both units through the use of worked examples and then they are challenged to apply this to a series of exam-style questions which have been differentiated so students of differing abilities can access the work

This lesson explains the properties of typical covalent simple molecular compounds and introduces diamond and graphite as giant substances. The lesson PowerPoint and accompanying resource have been primarily designed to cover point 1.34 of the Edexcel GCSE Chemistry & Combined Science specifications but also links to points 1.35 - 1.37 where the structure and uses of the giant covalent substances are described. The lesson begins with a quick recap task where students have to recognise a covalent bond from a description and fill the missing part. Moving forwards, they are introduced to the fact that covalent molecules can be simple or giant. They are then presented with a table showing some properties of covalent molecules and having to group them as simple or giant in the short space of time that the table remains displayed on the board. This task challenges their observational skills, something which will again be tested later in the lesson as they study the structure of graphite and diamond. Time is taken to ensure that key details such as the strong covalent bonds in both sets of molecules is understood and that it is the weak intermolecular forces which are actually responsible for the low melting and boiling points. The last part of the lesson introduces diamond and graphite as allotropes of carbon and students will briefly learn why one of these conducts electricity whilst the other doesn’t. If you want a lesson about these allotropes in more detail, then please look for “Diamond and Graphite”. Progress checks have been written into the lesson at regular intervals so that students are constantly assessing their understanding and so misconceptions are quickly identified.

This highly detailed and engaging lesson presentation (143 slides) acts as an excellent revision tool for students who are approaching their 1st OCR Gateway A GCSE Chemistry paper which includes the topics found in modules C1 - C3. This lesson uses a range of exam questions with explained answers, quick tasks and quiz competitions (such as UNLOCK the SAFE) to encourage the students to assess their understanding of the specification content and ultimately recognise any areas which will need further attention before the exam. The topics that are covered in this revision lesson include: Ionic, covalent and metallic bonding Atomic structure Using the Periodic Table Mole calculations Balancing symbol equations Conservation of mass Pure and impure substances Chromatography Calculating energy changes in reactions Reaction profiles Endothermic and exothermic reactions The detail in this presentation means that it is likely to be spread over a number of lessons and small chunks can be used at a time when revision needs to be specific.

A fully resourced lesson presentation (53 slides) and associated worksheet that uses a combination of exam questions, understanding checks, quick tasks and a quiz competition to help the students to assess their understanding of the topics found within TOPIC 5 (Energy changes) of the AQA GCSE Chemistry specification (specification point C4.5). The lesson includes useful hints and tips to encourage success in assessments. For example, students are shown how to use the energy change in a chemical reaction to work out if it is an endothermic or exothermic reaction. The topics that are tested within the lesson include: Endothermic and exothermic reactions Reaction profiles Calculating energy changes in reactions Fuel cells Students will be engaged through the numerous activities including a summary round called “E NUMBERS” which requires them to use all of their knowledge to work out the type of reactions that are shown.

An engaging lesson presentation (67 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 7 (Organic chemistry) of the AQA GCSE Chemistry specification (specification point C4.7) The topics that are tested within the lesson include: Crude oil, hydrocarbons and alkanes Fractional distillation and petrochemicals Properties of hydrocarbons Cracking and alkenes Alkenes Alcohols Carboxcylic acids Addition polymerisation Condensation polymerisation Students will be engaged through the numerous activities including quiz rounds like “What FRACTION of this is correct” and “Are you on FORM” whilst crucially being able to recognise those areas which need further attention

This is an engaging and practical-based lesson which uses the background idea of a man needing to make crystals for a date to engage students into understanding how the separation methods of filtration and crystallisation work. Like all of the lessons in the separation topic, a lot of the key terms sound similar and are often wrongly used by students. For this reason, time is given in the lesson to ensure that students can use them correctly, especially when describing filtration. In line with the background of the lesson, students are challenged to come up with the apparatus and substances needed to make the crystals. A method is provided so should the teacher choose, students will be able to carry out the practical and produce the copper sulphate crystals. Progress checks are written into the lesson at regular intervals, which question the students on this lesson topic and that of related ones and the final task of the lesson involves an exam question where students have to describe the method and equipment needed to make crystals. This lesson has primarily been written for GCSE students (14 - 16 years in the UK) but is appropriate for younger students who are studying the separation topic

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.

A fast-paced lesson that looks at the key details of the different substances which are found along the pH scale. This lesson has been designed for GCSE students and to build on the foundation knowledge that they picked up at KS3. Along with the obvious Scientific knowledge associated with the lesson, both numeracy and literacy skills are challenged during the lesson. Time is taken to ensure that the meaning of pH is understood and new terms such as base are introduced, so that these are recognised when written in assessment questions. Students will recall the scale numbers associated with acidic, neutral and alkaline solutions and their knowledge will be extended through the introduction of hydrogen and hydroxide ions. A method for taking a pH reading using a pH probe is included which can be used should the teacher chose that it is required. Progress checks are written into the lesson at regular intervals so that students can constantly assess their understanding.
