Thirsty Flowers Question: I wonder what will happen if I add food colouring to a vase of flowers? Hypothesis: What is your prediction? These are some ideas from Room 10 students: The flowers will die, the water will change colour, the flowers might get some stripes, the flowers will change colour. Method: Equipment White flowers A vase or glass Warm water Food colouring Steps 1. Pour the water into the vase 2. Place the flowers into the vase. 3. Add some food colouring – about 20 drops. 4. You can set up several colours in different vases. 5. Observe over the next 24 hours
Conclusion : What happened? Was your prediction correct? Why do you think this happened? Fair test: What would you change if you did the experiment a second time? Remember for it to be a fair test to compare to the first experiment you can change only one thing. Some options are: the shape of the vase; the colour of the flower; the amount of food colouring, the temperature of the water; the type of flower; use different food colouring.
