These PowerPoints will allow you to teach students how to calculate reacting masses (the mass of product made by a given mass of reactant and vice versa). Two PowerPoints are provided: Higher-tier lesson The PowerPoint (plus worksheet with exam-style practice questions) will allow you to teach Higher-tier only content on stoichiometry and then use this alongside numbers of moles to calculate reacting masses. Foundation-tier lesson Foundation students need to learn how calculate reacting masses but they do not need to learn how to calculate numbers of moles. The PowerPoint aimed at Foundation students revisits Relative Formula Mass and shows how to use this to approach Reacting Masses in a different way. It can also be used as backup for Higher students who struggle with Moles. The resources are easy to follow for teachers, readily accessible for students and are appropriate for Combined and Triple Science classes! Other lessons on Calculations involving Mass (including the preceding lesson on Moles) are available from my shop. They can be purchased individually or, alongside this lesson, as part of a whole-topic bundle.

This PowerPoint (containing exam-style practice questions) will allow you to teach the GCSE 9-1 Chemistry content on Limiting Reactants and using moles to calculate the limiting reactant from mass data. The resource is easy to follow for teachers, readily accessible for students and is appropriate for Combined and Triple Science classes, HIGHER TIER ONLY! Other lessons on Calculations involving Mass (including the preceding lessons on Moles and Stoichiometry) are available from my shop. They can be purchased individually or, alongside this lesson, as part of a whole-topic bundle.

This PowerPoint will allow you to deliver the GCSE 9-1 Chemistry Core Practical in which copper sulphate salt is prepared from copper oxide and sulphuric acid. It includes an easy-to-follow method to share with students, plus a brief look at how this method could be applied to a six-mark question. The resources are easy to follow for teachers, readily accessible for students and are appropriate for Combined and Triple Science classes, Foundation and High-tier. Other GCSE lessons (including other lessons on Acids and Alkalis) are available from my shop. They can be purchased individually or, alongside this lesson, as part of a whole-topic bundle.

This full Lesson PowerPoint will allow you to teach students the GCSE 9-1 specification Chemistry content on breaking down hydrocarbons (cracking) and comparing hydrogen versus petrol as fuels for vehicles.The resource is accessible for students, easy for teachers to follow and is appropriate for Combined and Triple Science classes, Foundation and Higher tiers. Note: this lesson covers the Edexcel Paper 2 specification point on hydrogen fuel cells which is relevant to both Combined Science and Triple Science students: “Evaluate the advantages and disadvantages of using hydrogen, rather than petrol, as a fuel in cars” For full coverage of the Triple-only Paper 1 content, evaluating hydrogen fuel cells alongside chemical cells, see my separate lesson “SC16a Chemical Cells and Fuel Cells”.

This PowerPoint will allow you to teach the GCSE 9-1 specification Chemistry lessons on Yield and on Atom Economy. The resource is easy to follow for teachers, readily accessible for students and is appropriate for Triple Science classes, Foundation and Higher tiers.

Full Lesson PowerPoint sufficient to teach the GCSE 9-1 specification Chemistry lessons on Transition metals and their uses, plus general properties and uses of metals. The resource is easy to follow for teachers, readily accessible for students and is appropriate for Triple Science classes, Foundation and Higher tiers.

This PowerPoint will allow you to teach a broad range of abilities about isotopes and calculating relative atomic mass. The resource meets all required specification points for the Edexcel 9-1 GCSE course. It is accessible for students, easy to follow for teachers and is appropriate for Combined and Triple Science classes, Foundation and Higher tiers. Only the Higher students need to be able to calculate relative atomic mass - this is signposted throughout the lesson. You will also need to download the free worksheets “SC3c_Isotopes worksheets and mark-schemes” from my shop - OnSpecScience.

Full Lesson PowerPoint (with independent learning tasks and suggested practical demo) sufficient to teach the GCSE 9-1 specification Chemistry lesson on alkenes. It also serves as a good introduction/reminder for the structures of the other homologous series that need to be taught (alkanes, alcohols and carboxylic acids). The resource is accessible for students, easy for teachers to follow and is appropriate for TRIPLE SCIENCE ONLY, Foundation and Higher tiers. Best taught at some point after my lesson SC20a "Crude Oil, Hydrocarbons and Alkanes".

This PowerPoint (with independent learning activity) will allow you to teach a range of abilities about collision theory, including the new material on activation energy, and how temperature, pressure, surface area and concentration affect rates of reaction. The resource meets all required specification points for the Edexcel 9-1 GCSE Chemistry course. It is accessible for students, easy to follow for teachers and is appropriate for Combined and Triple Science classes, Foundation and Higher tiers. You will also need the FREE resource “SC18b Collision theory worksheet” from my TES shop.

Full Lesson PowerPoint sufficient to teach the GCSE 9-1 specification Chemistry lesson on the recycling of metals and life-cycle assessments of manufactured products. The resource meets all required specification points for the Edexcel 9-1 GCSE Chemistry course. It is accessible for students, easy to follow for teachers and is appropriate for Combined and Triple Science classes, Foundation and Higher tiers.

This PowerPoint is designed to introduce students to Balanced Chemical Equations and links balanced equations with the Law of Conservation of Mass. The lesson is accessible for students, easy to follow for teachers and is required learning for Combined and Triple Science classes, Foundation and Higher tiers. Be aware: this resource is aims to teach students the basics of balancing equations and it assumes no prior knowledge / experience. As such, this content may take a whole lesson to cover with some classes but could be completed very quickly with students who have previous experience of balanced equations. Follow-up lessons on Calculations involving Mass are available from my shop individually or, alongside this lesson, as part of a whole-topic bundle.

This PowerPoint (plus worksheet) will allow you to teach a broad range of abilities about how to calculate relative formula masses and empirical formulae. The resource is required learning for the Edexcel 9-1 GCSE Chemistry course, Combined and Triple Science classes, Foundation and Higher tier. It is accessible for students and easy to follow for teachers. Follow-up lessons on Calculations involving Mass (including a practical lesson on Empirical Formula) are available from my shop. They can be purchased individually or, alongside this lesson, as part of a whole-topic bundle.

This PowerPoint (plus worksheet) are designed to introduce the meaning of concentration in Chemistry and teaches students how to use cubic decimetres to calculate concentration of solutions in g dm-3. The lesson is accessible for students, easy to follow for teachers and is required learning for Combined and Triple Science classes, Foundation and Higher tiers. Be aware: this resource covers concentration in g dm-3 only. Triple Science students will also need to learn about concentrations in mol dm-3 but this is covered in a later lesson, once moles have been introduced Follow-up lessons on Calculations involving Mass are available from my shop individually or, alongside this lesson, as part of a whole-topic bundle.
