A Fun Plant Experiment to Try at Home
Without water, plants would die. How does water get from roots of a plant to the other parts of the plant? The water travels through" small pipes" to all parts of the plant. And here is a scientific experiment to show it.
What we need:
* a celery stalk(芹菜茎) with leaves
* a knife
* some red food colour from tomatoes
* a glass of water
How we do it:
1. Put a few drops of the red food colour in the glass of water.
2. Cut the bottom(底部) of the celery stalk and place the celery in the water.
3. Leave the celery stalk in the glass of water for a few hours.
4. Take the celery stalk out of the water and cut it into pieces across the stem.
What happens:
You can see red food colour in all cross parts from the bottom of the celery stalk right up to the leaves.
Why it happens:
The water, with the red food colour, has run in the celery stalk through the small pipes in it. The experiment, therefore, shows that the small pipes in the plant allow water to reach all parts of it. The red food colour shows where the water has travelled in the celery stalk.
