In this classic science experiment, students report on the colours produced when flame tests are carried out on different metal salts.
In this practical, students predict and observe what happens when water and alcohol, and water and oil are mixed.
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.
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.
In this experiment, students see if dyes bond differently depending on the material, and what effect this has.
In this experiment, students report their findings when bread, covered in butter, is placed in a microwave without the turning plate. They also use their data to calculate the speed of light.
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.
