I just finished putting together a brand new PDF on Lulu.com for the Outdoor Hour Challenges. It gathers all the seasonal tree and weather study challenges into one document for you to download for free.
It includes Challenges #11, #20, #36, #39, #40, and #47 all into one easy to print document.
I am going to be deleting the files from SaveFile.com. If I missed a link within the challenges on the blog, please remember that all the downloads will eventually be available over on Lulu.com and they will be listed on the right sidebar of my blog.
I am trying to streamline things a bit.
Hope this helps some families with their nature study.
