Outdoor Hour Challenge - Dandelions


We had to leave our for-sale house for an hour again today so people could go through it, and before we left I let the children choose if they wanted to do an Outdoor Hour Challenge on maple trees or dandelions.  They chose dandelions, so I loaded up my bag with supplies and we headed out.


As we walked to the park, Little Man and Brown-Eyed Boy picked dandelions for me, pulling them from their host plants and proudly carrying them to me.  I gathered them together and laid them beside me on the bench once we arrived at the park.




I let The Ones I Love play while I read the Handbook of Nature Study, pages 531-536, and obtained some background information about dandelions.  (Did you know that their name comes not from their lion's-mane-like blossoms, but from their leaves which look like lion's teeth in profile "dents de lion"? Well, you do now!)




The play was going so well, and I was so intrigued by my study of the dandelions the boys had brought to me, that our hour passed quickly.  






It wasn't until we were home that we continued the dandelion study.  While we ate our snacks, I read a few highlights from the Handbook:


One spring when all the vegetables in my garden were callow weaklings, I found there, in their midst, a dandelion rosette with ten great leaves spreading out and completely shading a circle ten inches in diameter; I said, "Look here, Madam, this is my garden!" and I pulled up the squatter.  But I could not help paying admiring tribute to the taproot, which lacked only an inch of being a foot in length.  It was smooth, whitish, and fleshy, and, when cut, bled a milky juice; it was as strong from the end-pull as a whipcord; it also had a bunch of rather fine rootlets about an inch below the surface of the soil and an occasional rootlet farther down; and then I said, "Madam, I beg your pardon; I think this was your garden and not mine."
HNS p.532


I sent My Girl and Little Man outside to gather some specific specimens. My Girl brought in a dandelion plant, complete with root intact. 




 Little Man was brought five dandelion buds at various stages of development.






We then began our observations.  My Girl and I sketched and described the leaves of a plant, while Little Man dictated his description to me and I wrote it in his nature journal.  Then we investigated the root, noting the things about it that make it such a hardy little plant, so resistant to removal.


I described to the children some of what I'd read earlier about the buds and blossom heads, one particularly interesting point being that a dandelion is a composite flower - each yellow head is actually hundreds of small florets tightly packed together.


Out came the paring knife and cutting board, and the intricate examination of the buds and roots began. 




The children enjoyed looking at the tiny internal parts of the flower heads and buds, and My Girl's nature journal drawings are quite satisfactory. 



I, too, completed my journal entry, and included the exerpt from a poem by Lowell about this "dear common flower" --


'Tis the Spring's largess, which she scatters now
To rich and poor alike, with lavish hand,
Though most hearts never understand
To take it at God's value, but pass by
The offered wealth with unrewarded eye
HNS p. 531

  2. Excellent study of the dandelion! Isn't it amazing how much you can learn about something you have seen all your life? I love this kind of investigation and it will be something you and your children will remember for years to come.

    Your journals are very nicely done...great example doing one yourself Mom. :)

    Thank you so much for sharing your study. Could you please submit it to the OHC Blog Carnival?

    I look forward to your next study.

  3. L and Barb, you'll both be thrilled (maybe) to know that I was inspired to turn this into a post for my 100 species challenge.

    I think the spring is really moving in me and getting me looking at the world around again. Creation is so beautiful!
