Today in science we looked at flower stems and how they supply the water to the flower. The water travels through the stem and feeds the flower. I found it interesting that because the flowers had been cut from their plant 9 hours before the flower was thirsty. We put in some red food colouring and in just 10 minutes the white roses started to turn a peachy colour. We did the same with the blue colouring and it had the same effect. I found the roses surprising as blue is not a colour of roses in nature.
