Plants get water from their roots!

We were finally able to see some visual evidence that plants get their water through their roots, not through their leaves.

The difference was mainly in the flowers, but it was sufficient to allow the kids to see the difference, which was the important part. When we measured, though, we did find that the pink plant had grown a centimeter while the red plant was actually 3 centimeters shorter. The leaves were that much less rigid. We only measured to the top of the leaves, not the flowers, since those have a cycle and may or may not have been there when it came time to measure.

Once we completed the lab, we pulled out the foil and watered them both at the roots. The red flowers had perked back up by the end of the day when Daddy came home. He noticed right away that we had watered it.

Once we finished up that lab, we talked about the different parts of the plant and what part of what plant we eat. The curriculum calls for making a "Plant Parts Salad," but, well, the idea did not appeal to my kids or myself. We made a list of what we could put in, but we didn't make a salad.

Our final plant lab is still in a holding pattern. We are STILL waiting for the leaves on the plant to change color!!! Apparently our plant is just too healthy, which is odd, since I horribly neglect my plants!

Thank goodness! My inner gardener can't bear to see a plant look thirsty!
