Experiments with food colouring are a great way to introduce children to the world of science through play. Thanks to simple and colourful experiments, children can discover the principles of chemistry and physical phenomena in a way that is both educational and fascinating.
The first experiment the pupils were able to investigate was the effect of washing-up liquid on dyes in milk. The aim of the experiment was to show how the liquid reacts with the fats in milk and how this affects the movement of molecules and the spread of dyes. The next experiment involved mixing dyes in shaving foam. The aim of the experiment was to show how dyes spread in the porous structure of the foam and to observe the mixing of colours and how colourful patterns can be easily created and physical phenomena observed.
