High Flyin' science experiment!  The 4th grade classes constructed their own kites and took them outside for a  trial run!  We had such fun working in groups to construct the kites and then collaborating on ways to get them airborne.  Soaking up some fresh air sure helped morale, the kites weren't successful fliers, but students did gain some knowledge on what to do next time.
***Any time, any place, learn!*** ;)
