Resource
Bubble 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.
Resource
Making 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.
Resource
Plaster 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.

Roman 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.
Resource
Roman commerce in pigments

Did the Romans use the same materials as the Greeks in their painting? And where did the pigments come from?
Resource
Ancient 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.
Resource
Verdigris 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.
Resource
How 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
Resource
Magic 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.
Resource
Herschel infrared experiment

In this experiment, students measure the temperature thermometers reach as they are placed throughout (and beyond) the spectrum of visible light.
Resource
Invisible inks

In this experiment, students test a variety of substances to see if they can be used as an invisible ink.
Resource
Spinning colour top

In this experiment, students observe, describe and explain what happens when a multicoloured disc spins at a high speed.
Resource
Making a rainbow

In this experiment, students observe what happens to white light as it passes through water droplets.
Resource
Were 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.
Resource
Radiography

Part of the art conservation process is the examination and investigation of the artefact to determine its structure, make-up or stability. This resource investigates the two main types of radiography used: x-ray and gamma.
Resource
Flame tests using metal salts

In this classic science experiment, students report on the colours produced when flame tests are carried out on different metal salts.
Resource
Oil and water mix

In this practical, students predict and observe what happens when water and alcohol, and water and oil are mixed.
Resource
Making an oil-water emulsion

Students observe what happens when oil and water are mixed, and how the results of the experiment change when various substances, including an emulsifier, are added.
Resource
Three colours from the same dye-bath

In this experiment, students see if dyes bond differently depending on the material, and what effect this has.
Resource
Tyndall effect- why the sky is blue

In this experiment, students observe and report on the Tyndall effect. Also, students use their knowledge of the properties of mixtures and emulsions, and light to explain their observations.
