These PowerPoints and worksheets will allow you to teach HIGHER TIER ONLY GCSE Chemistry content on Moles. This lesson introduces the concept of a mole in terms of Avogadro’s number, exemplifies how to calculate the number of moles from mass of a substance and vice versa, and shows how to use moles to calculate numbers of particles of a substance **There are two versions of this lesson and worksheet provided. One is aimed at Triple Science students only, as it includes coverage of concentrations in mol dm-3, which is something that Combined Science students do not need to learn ** Other lessons on Calculations involving Mass (including subsequent lessons on using moles) are available from my shop. They can be purchased individually or, alongside this lesson, as part of a whole-topic bundle.

This PowerPoint is designed to introduce the Law of Conservation of Mass, closed systems and looks at simple examples of conservation of mass in solutions and chemical reactions. This 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 the basics; it does not deal with more complex ideas linked to conservation of mass (e.g., reacting masses) as they are covered in a later lesson. As such, this content may take a whole lesson to cover with weaker students but will be completed very quickly with higher-ability / motivated students. 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 practical method sheet will allow you to teach a broad range of abilities how to determine the empirical formula of magnesium oxide from practical data they have collected. The resource meets the 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 is best taught following my lesson on “Formula Mass and Empirical Formulae”. Other lessons on Calculations involving Mass (including the preceding theory lesson) 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) 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 will allow you to teach a broad range of abilities about the differences between pure and impure substances, with additional info on how malting and boiling points determine the state of a substance. 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 (with suggested practical activity) will allow you to teach a broad range of abilities about the three states of matter, conversions between these states and how to prepare/interpret a heating curve. 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.
