- Using a celery stalk, make a fresh, clean cut with a knife at the bottom of the stalk.
- Pour some water into a glass jar and put some food colouring into the jar of water.
- Stand the celery in the jar of coloured water.
- Leave the celery in the water for a few days. This gives the stalk the best chance of absorbing dye.
- After a few days, the stalk is cut and the children observed the now ‘coloured’ pipes within the stem.
All plants need water to live. Their roots get water from the ground.
Plants use tiny pipes to transport liquid around them.
The pipes are usually difficult to see but we can make them visible if we use a dye.
