A lesson on titrations designed for the Edexcel 9-1 separate science specification. This resource includes three Power Points -- the first covers what titration is, what equipment is needed for titration and instructions on how to carry out a rough titration. The second Power Point is for a slow titration practical and the third Power Point goes over titration calculations based on exam questions.

A lesson on alloys designed for the Edexcel 9-1 separate science specification. The lesson covers what an alloy is, why alloys are stronger than pure metals and the properties and uses of alloys. Contains factsheets and a table for students to fill in and exam questions to complete.

A lesson on gas volumes and calculations designed for the Edexcel 9-1 separate science specification. Lesson goes over what molar volume of a gas is, how to calculate the volume of a gas from moles (and vice versa) and how to apply gas volumes to reacting mass calculations. Contains exam questions and calculation questions for students to complete on the Power Point with answers – no printing required. Update: Optional worksheet included if you want to print it out to give students extra practice – I used it as a starter for the following lesson.

A lesson on yield and atom economy designed for the Edexcel 9-1 separate science specification. This lesson goes over how to calculate per cent yield, factors influencing yield and how to calculate atom economy. Contains slides with calculations for students to carry out, with the steps and answers appearing with a click. No printing required.

A lesson on alkenes designed for the Edexcel 9-1 separate science specification. A lesson on alkenes (what is an alkene, naming alkenes, drawing alkenes, testing for alkenes, and what an addition reaction is). Includes a gap-fill, exam questions and a practical. No printing required.

A lesson on what a mole is, how to convert between moles and particles and how to calculate moles from masses (and vice versa). This lesson is higher only content. Designed for the Edexcel 9-1 spec.

A lesson on cracking designed for the Edexcel 9-1 spec. The lesson covers what cracking is, why cracking is needed and the products of cracking. There are exam questions on the slides for students to complete. This presentation is for the combined science course and does not include detail from the separate sciences specification.

A lesson on flame tests and photometry designed for the Edexcel 9-1 separate science specification. Lesson covers how to carry out a flame test on a solid, what flame photometry is and how to use flame photometry to identify a compound or determine the concentration from a graph. No printing required.

A lesson that covers the compounds of Group 2 elements. It goes through the uses of Group 2 compounds, reactions of Group 2 oxides with water and trends in the solubility of Group 2 hydroxides. Questions and answers are on the slides for students to work through – no printing required. Designed for the OCR A Level specification.

A lesson that covers trends in melting points across Periods 2 and 3. The lesson describes how carbon, silicon and boron form giant covalent lattices. It then covers how the type of bonding changes across a period and periodic trends in melting points.Questions and answers are on the slides for students to work through – no printing required. Designed for the OCR A Level specification.
