A lesson on mass spectrometry designed for OCR A level. Lesson includes what a M+ peak is, how to calculate the empirical formula using a M+ peak and percentage composition, fragmentation patterns and exam questions on identifying alcohols and alkanes from a mass spectrum. Includes a handout of the mass spectra used in the lesson to print for students so they can annotate.

A collection of four bronze/silver/gold starters (with answers on following slide) for the new OCR A level specification. Starters are for the final part of Module 4 and include: practical techniques, synthetic routes, mass spec and IR.

A collection of six bronze/silver/gold starters (with answers on following slide) for the new OCR A level specification. Starters are for Module 4 and include: properties of alcohols, oxidation reactions of alcohols, dehydration of alcohols, substitution and haloalkanes (2 on this) and haloalkanes and the ozone layer.

A lesson covering haloalkanes and the ozone layer designed for the OCR AS chemistry specification. The lesson goes why the ozone layer is important, what CFCs are and their uses and the free radical reactions between CFCs and NO and ozone. The presentation contains questions (and answers) for students to work through on slides, so no printing is needed.

A lesson on reactivity trends in the rate of hydrolysis of haloalkanes designed for the OCR AS chemistry specification. The lesson goes over impact of changing the halogen on the rate of hydrolysis and contains a practical for the students to investigate the rate of hydrolysis. The presentation contains questions for students to work through on slides, so no printing is needed.

A lesson introducing alcohols and their properties designed for the OCR AS chemistry specification. The lesson goes over how to classify haloalkanes as primary, secondary and tertiary, what substitution and nucleophile mean and the mechanism for nucleophilic substitution (Sn2). The presentation contains questions (and answers) for students to work through on slides, so no printing is needed.

A lesson on reactions of alcohols designed for the OCR AS chemistry specification. The lesson goes over what an elimination reaction is, how to predict the products of an elimination reaction, and combustion of alcohols . The presentation contains questions (and answers) for students to work through on slides, so no printing is needed.

A lesson on the oxidation reactions of alcohols designed for the OCR AS chemistry specification. The lesson contains a practical on testing alcohols with potassium dichromate, the equations for the oxidation of alcohols into aldehydes, ketones and acids and questions for students to work through (with answers). The presentation contains questions (and answers) for students to work through on slides, so no printing is needed.

A lesson introducing alcohols and their properties designed for the OCR AS chemistry specification. The lesson goes over how to classify alcohols as primary, secondary and tertiary, why alcohols are more soluble in water than alkanes and trends in boiling points. The presentation contains questions (and answers) for students to work through on slides, so no printing is needed.

Includes a Power Point presentation that reviews all of the core practicals from Edexcel 9-1 combined science. There are a few slides per practical that briefly summarises it and then question and answer slides for the students to complete. An exam questions for each practical is included. Resource also includes 40 marks of exam questions on the core practicals to set as a test/homework. I have not used any of the exam questions from the sample papers so this resource can be used as a revision for mocks.

A Power Point summarising the 14 key calculations from the Edexcel 9-1 combined science specification. The presentation goes over each calculation and provides questions for students to work through on slides -- no printing required. Contains all the higher only content.

A lesson that covers what a limiting reagent is, how to find the limiting reagent from masses (this is also found in the combined science specification), how to find the limiting reagent from the volume and concentration of solutions (separate chemistry) and how to find the limiting reagent from gas volumes (separate chemistry). This lesson is designed for the Edexcel 9-1 specification, separate chemistry and covers higher only content.
