Our first chapter in science was called ALL ABOUT PLANTS. It talked about woodlands, prairies, marshes, deserts, what plants lived there, how plants have adapted to their environments and what kind of things plants do to survive. One of the experiments was placing stalks of celery in water to see if it needed roots to absorb water. I had a mason jar, the celery, and as a tip from my MIL I also had food coloring. We chose red.
The kids drew their predictions for what would happen. On the first day I was just putting the celery in the jar without any water. Just as they thought, the celery wilted.
I put water in on day 2 (like the experiment said to do) and added the selected red food coloring. I had them predict what would happen. They were right. The celery turned red (in the leaves and some parts of the ribs).
The kids enjoyed seeing the celery turn red so we kept it going. Then they asked if we could put other food coloring in. I thought, sure. Why not? Well, this is why - after ten days of a successful celery stalk changing color we added blue food coloring to turn the fresh water purple...and over the weekend the celery melted into the water so I had to toss it out.
I can only hope our experiments with space, seasons, gravity and the phases of the moon go better. Much better. At least the kids were able to work on some scientific processes!
