Celery Absorbing Water

Monday, February 22nd, 2010
After watching water being absorbed by paper, we thought we would see if a vegetable could absorb water too. Teacher had some celery, so we put it into a cup with water coloured with red food dye. We put another piece of celery in a cup with water coloured blue, and a third piece of celery, with its stem sliced a little, into both cups of coloured water. Even after a few hours we could see the celery changing colour, depending on which cup it is in. Tomorrow we will chop the celery stems to see the food dye in the celery.

We had a look at our sticks of celery this morning. We can really see the colours being soaked by the celery. Teacher cut the stalks and we could see the colours in the stalks. The most interesting stalk was the one that was half and half in each colour. Look at the way that stalk looked!
