After our 'Tree Day' Observation Walk last week we decided to investigate how plants 'drink' water. We decided to put celery sticks into jars of water. We put red food colouring into one jar and green food colouring into another jar. We placed a mark to show the level of the water and we left the jars at our investigation station for 24 hours.
Before - jars of water and celery.
After - Check it out!!
We noticed that the water is a little lower than our green mark. We can see red food colouring up along the stalk of the celery and the leaves have changed colour! We could not see anything on the celery in the green food colouring because celery is also green!
We now know that the plant 'drinks' water and sends it up through the plant to the leaves or flowers at the top.
