Our Y3 children have been so excited to see the changes in their flowers over the past week.
They discovered that plants 'drink' water through a process called osmosis. Osmosis is the movement of a liquid into a living thing, for example, if a plant needs water it will use osmosis to pull water through the roots until it has enough water to make food.
The plants take the water up to the top of the plant through capillary action.
Water sticks to itself and climbs up and down the plant through tubes which are similar to our veins. The plant will draw the coloured water up and some of the colour will stay in the upper parts of the plant, changing the natural colour of the top of the flowers!
