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.
