I’m not much of a flower person but it was still lovely to get some on Mother’s Day. At church, they gave each mother a stalk along with a prayer of thanksgiving. The boys also gave me one each, thoughtfully acquired by Grandma.
Since I had these flowers on hand, I thought it would be fun to do a classic science experiment with the boys, demonstrating capillary action in flowers.
The objective of the exercise (for preschoolers at least), is to demonstrate that plants need water to survive, and roots and stems are like the straws that help the plant to drink. All you need to do is:
- Fill a vase/container with water
- Add food colouring. Dark colours work best (we used blue)
- Put the flowers into the vase/container. If you are cutting the stems, do so underwater – the stalks, not you 🙂 – to prevent air bubbles from getting trapped and interfering with the result. Use white carnations/roses for best effect.
I found a really helpful online description here.
Here you can see the result from our experiment:
