Robynn learned during this experiment how plants absorb water through osmosis. The water travels throughout the plant and through a process of photosynthesis is used to make food for the plant.
We filled a clear jar with water and then added 4 drops of blue food dye.
Then we added celery; making sure we got some without the leafs chopped off. The first few hours you could only see a slight difference in the coloring. After 24 hours not that much more.
After 48 hours....
Well as you can see the celery sucked up it's water and distributed
it through out it's leafs. Robynn enjoyed this project a lot; even though there was a lot of wait time in between. She also enjoyed seeing how much water we had in the jar at the beginning (we put a rubber band at water level) and seeing how much the water level dropped from it's original mark. We are also currently trying this experiment with carnations, and a buddy of ours also suggested daffodils.
Our daffodils after 6 hours.
After 24 hours
For the carnation I took the stem and split it in half. I put one half of the stem in blue coloring, and the other in red. As you can see parts of the flower turned blue, red, and even purple where the two mixed together in the flower. Amazing!
Here is a link for this experiment and others fun one's for tot's.
