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 describes how the limiting reactant controls the mass of the product formed and explains how to deduce the stoichiometry. The PowerPoint and accompanying worksheet, which is differentiated, have been designed to cover points 1.52 & 1.53 of the Edexcel GCSE Chemistry specification and also covers those points in the Chemistry section of the Combined Science course. Step by step guides are used to go through worked examples so students are able to visualise how to set out their work. The lesson begins with a fun analogy involving sausages and potatoes so that students can identify that the potatoes limited the sale of food. Alongside this, students will learn the key term excess. Some time is then taken to ensure that students can spot the limiting reactant and the one in excess in actual chemical reactions and method descriptions. Moving forwards, students will be guided through two calculations that involve limiting reactants - those to calculate the theoretical yield and the other to calculate a balanced symbol equation. Other skills involved in these calculations such as calculating the relative formula mass are recalled and a few examples given to ensure they are confident. The question worksheet has been differentiated two ways so that any students who need extra assistance can still access the learning.

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 describes an ion as an atom with a positive or negative charge, and explains how cations and anions are formed in ionic compounds. The lesson PowerPoint and accompanying worksheet have been designed to cover points 1.22 - 1.24 of the Edexcel GCSE Chemistry specification and also covers the same points on the Combined Science course. The first part of the lesson focuses on atoms and specifically on getting students to recall that they contain the same number of protons and electrons and this is why they have no overall charge. By ensuring that they are confident with this fact, they will be able to understand why ions have a charge. Students will learn that ions have full outer shells of electrons and this change in the number of this sub-atomic particle leads to the charge. They are shown examples with aluminium and oxide ions and then are challenged to apply this new-found knowledge to a task where they have to explain how group 1, 2, 5 and 7 atoms become ions. The final part of the lesson looks at how ion knowledge can be assessed in a question as they have to recognise the electron configuration of one and describe how many sub-atomic particles are found in different examples. There are regular progress checks throughout the lesson to allow the students to check on their understanding. This lesson has been written for GCSE students but could be used with higher ability KS3 students who are looking to extend their knowledge past basic atomic structure

This lesson describes the differing properties of metals and non-metals and also relates this to their position in the Periodic Table. The lesson PowerPoint has been designed to cover points 1.18, 1.40 & 1.42 of the Edexcel GCSE Chemistry specification and this also covers those same points on the Combined Science course. The lesson contains a range of tasks including guided discussion points and quick quiz competitions which will engage and motivate the students whilst introducing key properties such as malleability and the ability to conduct electricity. Time is also taken to consider where the metallic and non-metallic elements are found in the Periodic Table and a series of progress checks will challenge the students to link together properties with position.

This lesson explains the properties of the fullerenes and focuses on graphene in terms of its structure and bonding. The PowerPoint and the accompanying resources have been designed to cover point 1.38 of the Edexcel GCSE Chemistry specification and also covers that same point on the Combined Science course. The lesson begins by recalling the definition of an allotrope. The students are then introduced to graphene and will begin to understand how this covalent structure is related to graphite and will know the shared properties of these two materials. Time is taken to ensure that students can explain why graphene is able to conduct electricity. Moving forwards, students will meet the family of allotropes known as the fullerenes and will learn some important details about a few of these including C60

This lesson describes how the empirical formula of a compound can be deduced from the masses of the different parts. The PowerPoint and accompanying resources have been designed to cover points 1.44 & 1.45 of the Edexcel GCSE Chemistry specification and also covers those points in the Chemistry section of the Combined Science course. This lesson uses a step-by-step guide to walk students through the method involved in calculating the empirical formula. Students are given a template to use as they are introduced to the questions and then encouraged to work without it as the lesson progresses. The students are shown how empirical formula questions can be made more difficult and hints are given so that students are able to tackle them and access all of the marks available.

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 revision lesson has been designed to challenge the students on their use of a range of mathematical skills that could be assessed on the six OCR Gateway A GCSE Combined Science papers. The mathematical element of the GCSE Combined Science course has increased significantly since the specification change and therefore success in those questions which involve the use of maths can prove to be the difference between one grade and another or possibly even more. The engaging PowerPoint and accompanying resources contain a wide range of activities that include exam-style questions with displayed mark schemes and explanations so that students can assess their progress. Other activities include differentiated tasks, class discussion points and quick quiz competitions such as “It doesn’t HURT to CONVERT”, “YOU DO THE MATH” and “FILL THE VOID”. The following mathematical skills (in a scientific context) are covered in this lesson: The use of Avogadro’s constant Rearranging the formula of an equation Calculating the amount in moles using mass and relative formula mass Calculating the relative formula mass for formulae with brackets Using the Periodic Table to calculate the number of sub-atomic particles in atoms Changes to electrons in ions Balancing chemical symbol equations Empirical formula Converting between units Calculating concentration in grams per dm cubed and volumes of solutions Calculating size using the magnification equation Using the mean to estimate the population of a sessile species Calculating percentages to prove the importance of biodiversity Calculating percentage change The BMI equation Calculating the acceleration from a velocity-time graph Recalling and applying the Physics equations Understanding prefixes that determine size Leaving answers to significant figures and using standard form Helpful hints and step-by-step guides are used throughout the lesson to support the students and some of the worksheets are differentiated two ways to provide extra assistance. Due to the detail of this lesson, it is estimated that it will take in excess of 3 hours of GCSE teaching time to cover the tasks and for this reason it can be used over a number of lessons as well as during different times of the year for revision
