Coloured Flowers

This activity is an amazing visual. It teaches how a plant absorbs water up it’s stem and nourishes its petals or leaves. The cut flowers take up water through their stem and the water moves from the stem to the flowers and leaves. Water travels up tiny tubes in the plant by a process called Capillary Action. Putting a coloured dye in the water in the vase allows us to observe capillary action at work.
