Celery Experiment

In Sapphire Class we have just completed an experiment using celery and coloured water. We put our celery into orange water and waited to see what happened. We made our experiment a fair test by making sure each jug contained the same amount of water and the same amount of food colouring.

We predicted that our celery would turn orange… and we were right!

We realised that this is because the celery had absorbed the orange water through its roots and the water had traveled up its stem.

We proved this by measuring the water level at the beginning and the end, the water level has decreased. Therefore we knew that the water had traveled into the plant and up the stem.

In one of our jugs the orange water turned clear and we don’t know why! If you know why this happened we would love it if you could comment on this post and let us know.
