Rainbow Water Density Tower
Aim - To observe how substances with different densities interact
Materials
Glasses - 1 per group
Food colouring (red, blue, green and yellow - you can make purple and orange by combining two colours)
Sugar or Salt (and measuring spoon)
Measuring cup - 1 per colour (you can have 6 colours to work with, or limit it to 4 colours)
Measuring syringes
Water (warm water from a tap or kettle)
Plastic spoons to mix the sugar and food colouring in the water
Pots of water to rinse syringes between each colour
Plastic plates or trays to protect the table from sticky sugar water
Results
Since the colouring of different densities did not mix together the colouring with the lightest density went to the top and the deepest went to the bottom and the one with the equal amount of sugar stayed in the middle here is an example of the result.
Explanation
Look at the websites below and also do research of your own - Then write a paragraph explaining ‘the science’ behind the experiment. Why do we see the results that we did?
Explanations
The experiment ended up showing coloured layers of water. This was because different amounts of sugar were diluted (dissolved) into each colour. This meant that each colour had a different density. Water or liquids with different densities don't mix.
