For this experiment:

1. You will need white flowers (any kind will do), different food colourings and the same number of small cups/vases as colours. 
2. Separate the flowers into individual cups/vases with the same amount of water in each. 
3. Predict (or hypothesize) what will happen to the flowers once the colouring is added. 
4. Add a few drops of different food colourings into each vase. 
5. Wait and check back at regular intervals – what can be observed each time?
6. Leave the flowers for a few days and discuss the results. Which colour produced the most dramatic difference in the flower? If the same amount of dye was used in each vase, why are the results different for each flower?
