Art historians and scientists use a variety of physical and chemical techniques to make discoveries and answer questions about art and artefacts. Explore some of them here.
In this practical, student gain an understanding of how cave painters may have used the natural rock formation to paint the animals and scenes onto them and how later painters have continued with this tradition.
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.
In this experiment, students determine what is meant by an alloy, produce their own (solder) and identify ow the alloy’s properties differ from those of its constituent elements.
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.
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.
In this experiment, students write a hidden message using invisible ink and watch what happens when a glowing splint touches their message.
In this experiment, students test a variety of substances to see if they can be used as an invisible ink.
In this practical, students create a marble effect on paper, using their knowledge of mixtures and hydrophobic solutions to explain the phenomena. Also, students use their evaluating skills to determine which method produces the best result.
This investigation looks at the topic of surface tension in a colourful way, where students create a tie dye effect with milk, water, washing up liquid and food colouring.
In this practical, students use methods which have been used for centuries to produce inks.
In this practical, students observe and report what happens when water is placed on waxed paper, and a splint or toothpick is positioned close to the droplets.
Blueprints use the cyanotype process invented by the astronomer John Herschel in 1842. In this experiment you will carry out an experiment to produce blueprint paper and produce an image or diagram using the blueprint paper.
