Considering Celery

This is a very fun science experiment to do with children. Fill about 1/2 inch of water into a glass and add food coloring. Place a piece of celery with leaves still attached into the colored water and keep an eye on it for a day or two.
Watch how the water travels up the stalk to the leaf and changes color. As you can see, we had the best luck with the color red.
Cut the stalk across and show children where the coloring is showing the tubes that carry the water up the stalk of the plant. This is an example of capillary action.

Enjoy!

I love the transpiration experiments and my children adore when we do them. We've had lots going this year as my oldest keeps picking flowers to give me and I turn them into coloured blooms for him. Our daffodil turned out beautiful and you could see on the petals were the viens went.
