Outdoor Hour Challenge: Field Horsetail Nature Study

I’m excited to be learning about the field horsetail this week for our nature study lesson. We have a patch of it that we’ve been observing on our street and along a favorite hiking trail. I hope to glean some new information about this interesting topic right alongside all of you.

It isn’t particularly pretty but it does have an interesting life cycle story. Use the Handbook of Nature Study by Anna Botsford Comstock (Lesson 196) along with the link to the original challenge below to learn more.

Please note that the original challenge and the ebook have the wrong page numbers for the Handbook of Nature Study. The correct pages are 706-709 or just look for Lesson #196.

If you have access to the ebook, there are two notebook pages to choose from for your nature journal.

Alternate study: Take your outdoor hour time and look for any autumn weeds you have, especially those with seeds. Contrast your weed with what you learned about the field horsetail.
