When you go out to do your nature study have a focus of what you want to look at. One week it might be clouds, another a tree, the next week might focus on ants. Throughout the year observe a variety of nature. Remember that nature study is a lifelong endeavor. Each time you observe something in nature, try to learn one more thing about it.
Our Journaling a Year in Nature gives you help with focusing on what to observe in nature in the different seasons.
I looked at the sample of the Shared Wonder Birds and Weather curriculum. There may be some good things there but I didn’t see a lot of direction for what to do with your time outside or nature journal. I also found it odd that yoga was scheduled and can’t see how that has anything to do with nature study, birds, or weather.
It would be hard to tell much more without a deeper look at the recommended books.
