Plants need water

For our experiment we need celery

We also need water, red and blue food

colouring.

We pour water in two containers.

We mix red food colouring into one

container and blue food

colouring into another. We stir

the water.

We put the stalks of celery in the water.

We leave it for several hours even overnight.

The next day we see red and blue marks on

the leaves.

We cut up the stalk.

There are red and blue lines

inside the stalk.

We discover that water is absorbed and sucked up by a plant. It travels up

the plant and then into the leaves. A plant drinks

water.
