An online lesson plan, supported by video clips, which shows you how to engage students with an exothermic crystal stalagmite and instantly freezing water.

An online lesson plan, supported by video clips, which shows you how to structure practical activities for students to learn about conservation of mass.

An online lesson plan, supported by video clips, which includes the effect of smaller particle size on rates of reaction and the flame colours of different compounds.

A short revision video which covers the main points of rates of reaction.

A video tutorial and accompanying notes to explain a spectacular demonstration of the effect of particle size on reaction rate.

A video tutorial showing how to demonstrate the effect of a catalyst on the decomposition of hydrogen peroxide.

A video tutorial, with accompanying notes, showing how to use the methane rocket to help students to understand how and why we balance equations.

A pdf which contains instructions for demonstrating a very endothermic reaction between two solids.

A spectacular demonstration of combustion of an alcohol. The presence of carbon dioxide and water can be tested for in the products.

A short video clip that demonstrates the crystallization of sodium ethanoate (exothermic) and the reaction of barium hydroxide with ammonium chloride (endothermic). An explanation of the energy changes is then given.

This video recaps collision theory and uses some demonstrations to show the effect of concentration, temperature, catalysts and surface area.

A series of pages that cover reversible reactions, dynamic equilibrium, the effect of changing concentration, pressure and temperature, and then the contact process.

The Ri YouTube Channel's playlist for the Christmas lectures 2012, presented by Peter Wothers.

A comprehensive and engaging cartoon that summarises the main points about rates of reaction: measuring rates, collision theory, particle explanations of factors that affect rate.

This webpage links to revision notes, multiple choice questions and exam-style questions, all focused on rates of reaction.

An explanation of exothermic and endothermic reactions using ideas about breaking and making bonds.

This practical activity models the extraction of copper from malachite, which is a copper ore consisting of copper(II) carbonate. In the school laboratory, copper is extracted from copper(II) carbonate by first heating to form copper(II) oxide and then reducing to produce the metal. Teacher notes, apparatus list, student guidance and safety points are included.

A series of equations that need to be balanced using drop down menus for the stoichiometric coefficients.

A series of simple visual activities that will help students learn how to balance equations at different levels of difficulties.

A variety of quizzes on rates of reaction.

A selection of quizzes and activities focused on the reactivity series, rusting and redox.

A selection of quizzes and worksheets on exothermic and endothermic reactions.

Three pages that summarise the important concepts in rates of reaction.

A summary of complete and incomplete combustion of hydrocarbon fuels.

A simple page that summarises thermal decomposition using transition metals as an example.

Four pages that summarise the thermal decomposition of limestone, the uses of limestone and the uses of limestone products.

A comprehensive summary of exothermic and endothermic changes over four pages with an interactive quiz at the end.

A concise but comprehensive summary of complete and incomplete combustion.

A simple guide to different types of chemical reaction.

A series of pages that review ionic equations and precipitation reactions, including testing for sulfate ions and halide ions.

A comprehensive summary of reaction rates and how to measure them.

A comprehensive summary of the effects of concentration, temperature, surface area and catalysts on reaction rates.
