Flowers and water

How do flowers drink?

Experiment: Flowers and water

Hypotheses: Ask children how flowers absorb rain. Through their petals? Stems? Leaves?

Material:

• A few white flowers (daisies or other kind)
• A few celery sticks with leaves attached
• Food colouring (at least two colors)
• A few small glasses

Manipulations:

1. Pour water into a glass until is ¾ full.
2. Add a few drops of food colouring and stir well.
3. Deposit a flower in the glass.
4. Repeat using other colours. You can use the celery sticks too.
5. You have to wait several minutes before beginning to see the result of this experiment. Be patient!
6. Leave the flowers in the food colouring overnight for best results.

Explanations: Flowers drink water starting from their lowest extremity. The water slowly travels upwards through tiny pipes in the stem. Your water was colourful, and now you have multicoloured flowers! The principle is the same for all types of plants. Trees get water from the ground through their roots. The water travels up to the highest leaves!
