We performed an impromptu science experiment when Jack asked, "What are stems?" Luckily we had some daisies on the dining room table and some food coloring in the cabinet...
After quite a bit of waiting, the results were subtle (not as vibrant as I had hoped), but still interesting.
I think we'll try this experiment with celery next to see if the effect is more dramatic. But Jack saw enough to figure it out anyway. He observed, "So stems are like pipes that carry water!" He related it back to his construction frame of reference all by himself. I LOVE that he made that connection!
Who knew science could be so fun?
