Class experimentSeparating salts from seawater
Try this simple practical to show that seawater contains a mixture of different salts. Includes kit list and safety instructions.
-
Class experimentCarbon filtration and activated charcoal
Try this practical to remove objectionable tastes and odours from water using carbon in the form of activated charcoal. Includes kit list and safety instructions.
-
Class experimentWhat ions cause hardness in water?
Investigate how different cations and anions in dissolved salts affect the formation of a lather in this experiment. Includes kit list and safety instructions.
-
Class experimentComparing the melting points of solder, tin and lead
Test the melting points of lead, tin and solder to investigate solder as a solid mixture and alloy in this practical. Includes kit list and safety instructions.
-
DemonstrationDetermining the relative molecular mass of butane
Use this demonstration to calculate the relative molecular mass of butane using simple apparatus. Includes kit list and safety instructions.
-
Class experimentModelling alloys with plasticine
Try this class activity to explore how alloying can be used to change the properties of a metal. Includes kit list and teaching notes.

ResourceWere Ancient Greek statues white or coloured?
Renaissance artists studied the sculptures and monuments of Greece and Rome and emulated them in their own work, ie they imitated the art. This perspective of art has echoed down the centuries to influence the appearance of Western art and architecture today.
-
ResourceMaking a rainbow
In this experiment, students observe what happens to white light as it passes through water droplets.
-
ResourceSpinning colour top
In this experiment, students observe, describe and explain what happens when a multicoloured disc spins at a high speed.
-
ResourceInvisible inks
In this experiment, students test a variety of substances to see if they can be used as an invisible ink.
-
ResourceHerschel infrared experiment
In this experiment, students measure the temperature thermometers reach as they are placed throughout (and beyond) the spectrum of visible light.
-
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.
-
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
-
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.
-
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.
-
ResourceRoman commerce in pigments
Did the Romans use the same materials as the Greeks in their painting? And where did the pigments come from?
-
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.
-
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.
-
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.
-
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.
