A Powerpoint presentation covering addition of HX and halogens from the OCR new A-level specification. Lesson covers the trends in carbocation stability, addition of halogens (including mechanism) and addition of HX (mechanism and Markownikoff’s Rule). Second of a series of 3 lessons on addition in alkenes. Contains questions on slides, so no printing required.

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 worksheet (and key) containing empirical formula calculations. Includes finding empirical formula from molecular formula, molecular formula from empirical formula, empirical formula from reacting masses, empirical formula from percentage composition and writing a balanced equation from reacting masses. Designed as a revision aid for higher attainers and the Edexcel 9-1 spec.

A lesson on addition polymers designed for the Edexcel 9-1 separate science specification. Lesson covers what an addition polymer is, examples of mononmers/polymers, drawing monomers/polymers and properties and uses of addition polymers. Includes exam questions and factsheets.

A lesson on transition metals designed for the Edexcel 9-1 separate science specification. The lesson covers properties and uses of metals and transition metals.

Includes two Power Points on ions and ionic bonding. Could be used as two lessons or condensed into one depending on the ability of the group. Ions lesson covers: what is an ion, how ions are formed in terms of electrons, how to calculate the number of protons, neutrons and electrons in an ion. Ionic boding lesson covers: when do ionic bonds form, what is an ionic bond and dot and cross structures. Designed for the Edexcel 9-1 specification but would work for other exam boards as well.

A lesson covering the properties of simple covalent compounds designed for the Edexcel 9-1 spec. Covers the properties of covalent compounds, an explanation of why the compounds have these properties and a short practical. Slides also have exam questions for students to work through.

A lesson on alkanes designed for the Edexcel 9-1 separate science specification. The lesson covers what alkanes are naming alkanes and drawing alkanes. Exam questions are included on the slides. No printing required.

A lesson on equilibria and Haber designed for the Edexcel 9-1 separate science specification. The lesson reviews the factors that impact equilibrium, discusses factors that impact the rate at which a reaction reaches equilibrium and applies this to the Haber Process. Contains an exam question for students to complete. No printing required.

A lesson on homologous series for the Edexcel 9-1 spec. The lesson covers what a homologous series is, what a general formula is and what it would be for compounds in a homologous series and how homologous compounds compare in terms of chemical and physical properties. This lesson is designed for combined science and does not cover topics from the separate science portion of the specification.

A introduction to electrolysis lesson covering key words (e.g. anode, cathode, oxidation, reduction, electrolyte, etc), how to predict the product of electrolysis of a molten salt and how the ions move during electrolysis. Designed for the Edexcel 9-1 Combined Science spec.

A lesson on empirical formulas. It covers the method of finding an empirical formula by experiment, how to calculate the empirical formula from reacting masses and percentage composition and how to write a balanced equation from the reacting masses (this last topic is higher only). 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 covering the causes of acid rain, the problems caused by acid rain and the advantages and disadvantages of using hydrogen fuel cells compared to petrol in cars. Slides with exam questions for the new spec are included. Designed for the Edexcel 9-1 combined science course --the triple only content on fuel cells is not included.

A lesson on the sodium hydroxide cation tests designed for the Edexcel 9-1 separate science specification. Covers how to carry out the practical --sodium hydroxide test and test for ammonia and ionic equations for these reactions. No printing required.

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 collection of 13 starters for the Edexcel 9-1 specification on all of the separate chemistry 2 topics (alkanes, alkenes, alcohols, carboxylic acids, polymers, materials, ion tests and nanoparticles). Each starter contains a bronze/silver/gold set of questions. The next slide contains the answers.

A lesson covering what a lattice structure is, the difference between -ate and -ide and how to write the formula of a salt. Designed for the Edexcel 9-1 spec.

A lesson covering the properties of ionic compounds designed for the Edexcel 9-1 spec. Includes the properties of ionic compounds, gap fills (on the Power Point) on explanations of the properties, exam questions on slides and a practical (students investigate the conductivity of salt solutions).

A lesson that covers halogen displacement reactions. It contains a method and results for a halogen displacement practical and discusses how these are redox reactions. It also covers writing half-equations for these reactions. Questions and answers are on the slides for students to work through – no printing required. Designed for the OCR A Level specification.
