I just found another treasure at the Heart of Harmony Blog. (That blog is AWESOME!!) The new treasure is called Green Hour Challenges. Hear is a quote from the blog:
As promised, I am going to start a weekly challenge for families who are wishing to get started with nature study or need to have a focus for each week. We will start off in a gentle, easy to accomplish way and build from there.-Barb Harmony Art Mom
At this link you can read the rest of that post and find out all the details of the challenge. I plan on starting it this week with my boys. I think it’s going to be great because she uses the The Handbook of Nature book in the challenges and I love that book!
