ExperimentProperties of alkali metal compounds
Try this class practical to explore the physical and chemical properties of various alkali metal compounds. Includes kit list and safety instructions.
-
ExperimentThe thermal properties of water
Explore water’s boiling point, specific heat capacity and thermal conductivity in this demonstration. Includes kit list and safety instructions.
-
ExperimentRecovering water from a solution using a condenser
Use this demonstration to show how pure water can be recovered from copper sulfate solution using a condenser. Includes kit list and safety instructions.
-
ExperimentCatalytic oxidation of potassium sodium tartrate

ResourceChemhistory: cocaine
Professor Alan Dronsfield, chair of the Royal Society of Chemistry’s Historical Group, looks at the significance of cocaine in an historical context.
-
ResourceBubble volcanoes
In this experiment, students describe what is observed when ethanoic acid and sodium hydrogen carbonate are mixed, using key terms such as reaction, fizzing or effervesce and gas.
-
ResourceMaking concrete
In this experiment, students determine how different sized materials with binder increase the stability and strength of mortar and concrete. Also, students can test how altering the proportions of cement, water and different aggregates affects concrete’s properties.
-
ResourcePlaster of Paris
In this experiment, students produce Plaster of Paris, which they then use to produce a cast, in order to identify the items that have left an impression in an apple.

ResourceRoman art - wall painting techniques
Pompeii and Herculaneum have been described as towns frozen in time. Houses and villas with their furniture, food, people, jewellery and pets have been preserved. One thing that strikes all visitors to Pompeii and Herculaneum is the amount of colour on the walls of the buildings. It is perhaps the most obvious feature of Roman art.
-
ResourceRoman commerce in pigments
Did the Romans use the same materials as the Greeks in their painting? And where did the pigments come from?
-
ResourceAncient Roman art: an imitation of Greek art?
A traditionally accepted view of ancient Roman art is they borrowed from, and copied, Greek precedents. The picture, however, is more complex and recent archaeological research indicates Roman art is highly creative.
-
ResourceVerdigris copper
In this experiment, students deliberately corrode copper, to produce a pigment called verdigris. Students can then explain their observations using their knowledge of redox reactions.
-
ResourceHow to make a lake pigment paint
Use this experiment to show your learners how to make and analyse the properties of a lake pigment paint
-
ResourceMagic writing with sodium nitrate solution
In this experiment, students write a hidden message using invisible ink and watch what happens when a glowing splint touches their message.
-
ResourceHerschel infrared experiment
In this experiment, students measure the temperature thermometers reach as they are placed throughout (and beyond) the spectrum of visible light.
-
ResourceInvisible inks
In this experiment, students test a variety of substances to see if they can be used as an invisible ink.
-
ResourceSpinning colour top
In this experiment, students observe, describe and explain what happens when a multicoloured disc spins at a high speed.
-
ResourceMaking a rainbow
In this experiment, students observe what happens to white light as it passes through water droplets.
