This list of resources provides a range of spectacular demonstrations for Key Stage Three and Key Stage Four chemistry lessons. From simply mixing two chemicals to produce a beautiful or surprising effect, to the more ambitious and dramatic ...., these demonstrations have been designed to provide the wow factor for students.

A magical demonstration where it appears that pouring a jug of water into different glasses produces a range of different drinks. It is a great way to introduce a lesson on pH indicators at Key Stage Three and will hold students spellbound.
The demonstrations in this Teachers TV video are carried out by Dr Kay Stephenson from the Royal Society of Chemistry and Simon Quinnell of the National Science Learning Centre. They have been chosen to highlight various aspects of chemistry, such as rates of reaction and energy changes. Included are some helpful tips on how to carry out the demonstrations safely and successfully in the classsroom. This video is ideal for non-chemistry specialists and NQTs
This video shows how to use the chemistry of fireworks to demonstrate combustion basics, oxidation and oxidising agents, displacement reactions, flame colours and generating thrust. Particular attention is paid to explaining the risks and safety precautions.
This video shows a teacher having a training session with CLEAPPS in order to demonstrate four redox reactions safely and effectively into her Key Stage Four lessons. The 'screaming jelly baby' demonstration is spectacular when carried out correctly.
Expert chemists from the Royal Society of Chemistry and CLEAPSS demonstrate what happens when some demonstrations don't go according to plan and explain why this happens. They also give some alternative approaches to classic experiments.
Problems associated with cracking hydrocarbons, white phosphorus, making chlorine gas, and making copper sulphate crystals are demonstrated, and the experts give some top tips to make school science experiments a success.
This video shows how to carry out exciting demonstrations of the reactivity of elements in group one of the periodic table. Bob Worley from CLEAPPS explains the risks and safety procedures so that these demonstrations can be carried out more confidently. As well as the reactions of alkaline metals with water, burning sodium in chlorine, burning calcium in air, the reduction of copper oxide using magnesium powder and the reaction of sulphur with both iron and zinc are also demonstrated.
This is a simple and visually impressive demonstration which can be used at Key Stage Three to illustrate the properties of solids, liquids and gases or acids and alkalis.
This is a Teachers TV video which shows three short experiments which allow students to explore the concept of the conservation of mass. The three activities can be carried out in one lesson and are suitable for Year Seven students.
