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.
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.
