On 7 August, we did an experiment where we put a lily plant into a bottle of coloured water. This experiment is to show that the stem of the plant transports water to other parts of the plant. Although our lily plant withered and died, we had learned many valuable lessons. Firstly, the plant died because I added poster colour into the water. As the poster colour contains oil and other chemicals, it resulted in the plant to die. A food dye (used for making jellies)should be used instead. In addition, a white rose would be a better flower to be chosen for this experiment as the flowers of the lily plant are coloured pink. Hence, any change of colour will not be obvious. The stem of the plant was cut and my pupils were given the chance to touch them. From this experiment, they have learned that the stem of the plant really transport water to other parts of the plant. :)
