Transcript of The separating colours

separating colours Hypothisis Results The aim of the experiment Discussion Diagram and demonstration Method Method Equipment 1.Pour the milk into the container.
2.Add 3 drops of each food colouring into the milk.
3.Squeeze a small amount of dish washing liquid on to the cotton bud.
4.Now press down on the centre of the container for a few seconds. Conclusion This experiment demonstrates how coloured liquids can be seperated in to smaller particles when mixed with a heaver substance, being dish washing liquid. In this experiment we were able to demonstrate that all matter will break down in to small particles when mixed with more solid material. Cotton bud
Dish washing liquid
a bowl/container
food colouring
1 measuring cup The results show that when the food colouring is placed in the bowl of milk it continues to remain in its own form with in the milk. It does not spread with in the milk as the volume level of the food colouring is similar to that of the milk. By then adding just 1 drop of dish washing liquid the inpact is immediate as the heavier particles spread the food colouring in all directions and creates a sea of colour. As my experiment has proven that smaller particles will always break down when mixed with stronger substances. A classic example is the on going functions of the human body.The food we eat is digested by the stomach enzimes, and broken in to smaller particles for energy and protein.
