Science and plants

The boys in 4th and 5th classes investigated the vessels within flowers and plants. They looked at the parts of the plant, conditions for growth for plants and some of the processes within plants. Pupils investigated the water vessel (Xylem) and the food vessel (Phloem) within the stem of a plant. The flowers were put in a jar with a mixture of eater a food colouring. We predicted that the white petals of the flower would change to a redish colour (and the colours of the other colourings). The results are found below in the picture. 
The conclusion for the investigation was that water (and food) enters the plant through the roots, moves up through the roots, through the stem and into the leaves and petals etc. 
*Some of the investigations did not work properly and we predicted (guessed) that this was because the flowers were not freshly cut that day. 

Day 1: 
One week later:
If you look carefully and zoom in, you can see the lines (vessels) in which the water moved up inside the stem and into the petals. 
WELL DONE BOYS!
