My husband oddly enough brought this to my attention. Apparently there is a White House initiative to get all four graders and their families (including 4th grade teachers) to experience federal public lands. It began September 1, 2015 and runs until the end of August 2016. It looks like this is the first year so I am not sure if it is being offered this coming September 1st.
There seems to be an educator package that I thought would be good to look at with four activity guides. In my neck of the woods the activity guides would be good for after state testing as a way of introducing the program for summer fun (even though it seems good for the entire year).
So if you are a fourth grade teacher, or have a fourth grader at home, you might want to check it out!
Here is what is on the website:
