I was reading another blog this week and one of the activities mentioned came from this site: http://www.naturedetectives.org.uk/download/autumn/
It is a AWESOME site! If you haven't bookmared it yet I would highly suggest you do!
There are so many great ideas for activities and wonderful resources. I guess I should buy more paper for the printer so I can put together a few things as the leaves start the change solors and temps cool off enough for trips to the park!
