Life sized RhomboSTEAM! www.ten80elementary.com has a K-2 STEAM curriculum that has kids using engineering design process on a classroom scale. I love the idea of pointing teachers toward blogs like this with life-sized architectural projects.
I just heard about this at physical therapy! Homemade Ice packs: 1 part rubbing alcohol to 3 parts water, gets really cold, but never hardens so you can manipulate it. every athlete (or mom) should pin this!
