Part of our flower fun over the last few days involved our experiment for the Virtual Science Fair which was a lesson in backyard fragrances. But later that afternoon, I couldn't help playing around with colors and flowers like I did so often when I was younger.So with some of the cuttings we did of the bigger flowers, and with pieces from a bouquet the kids picked up for me when I was really, really under the weather last week, we set up an opportunity for Maddy, Owen, and Cora to see just how flowers absorb water.
- Coloring Flowers: I poured four glasses of water, and then I added a big blob of red, yellow, green, and blue food coloring to each separate glass.
our flowers, waiting for color
Maddy used the whisk to dissolve the food coloring, and then we added flowers. The daisies had been around for a while, but the tulips and daffodils were right outta the garden.
We added the flowers, and then we waited.
. . . and then we waited some more.
And about four hours later (yes, there was a lot of stuff shoved in between this little experimento), we spotted tiny bits of blue around the edges of the tulip and blue around the center of the daffodil.
We didn't check the flowers again until breakfast the next day.
Finally, the next morning, we noticed that our tulip had really absorbed the blue but that the red really wasn't that noticeable. We also observed that the older flowers didn't absorb as much as the more fresh flowers.
We didn't get into the science of it all or the specifics about why it happened; I really just wanted Maddy, Owen, and Cora to see how flowers absorbed (or 'drank' as they said) water. We'll try this experiment with Queen Anne's Lace which is found all around Maryland and Pennsylvania come summer because that's what I remember using as a kid, and it is a really simple--but worthwhile--bit of science learning for our little ones.
And that's it. We've been enjoying the sunshine, playing lots with our new pooch, and trying to get back to Healthyville, which really hasn't been easy for us. But the rain is coming, and hopefully it'll wash away this pollen and our colds.
I can not wait to do this when my kiddos get older! I remember doing this with carnations when I was a little girl! :)
ReplyDeleteI love this experiment, it's so much fun to do.
ReplyDeleteWhat a great idea to use spring bulb flowers. A few weeks ago we dyed carnations which was a big hit.
ReplyDeleteWe did it with mums and waited overnight. We got similar results!

that's cool! i thought you could only do it with carnations (which we tried once and it didn't work--only i could fail at this experiment!)
ReplyDeleteHow cool is this! When my kids get older this would be so much fun to do w/them!
ReplyDeleteHow fun to try other flowers!
ReplyDeleteWhen we bought our carnations, the florist wrapped them baby's breath. I was going to try the it but got side-tracked. It does take a while, doesn't it?
This is such a cool experiment. I want to try it with my kids.
ReplyDeleteI think it is cool how with the carnations you can see the dyed water going up the stem
ReplyDeleteI'm going to try this with my kids too. I never thought about doing this .. we never got around to coloring our eggs for Easter so using that dye would work perfectly. Thanks for the great idea.
ReplyDeleteI did this with my daughter too for her science project. We used white carnations and several glasses with different color water. So much fun!
