For our science co-op group we studied the heart. So a friend of mine who was teaching this unit brought in an actual cow heart to look at the chambers, arteries, veins, muscle, etc. It was funny to see what kids were utterly amazed and which ones were a little squeamish. Of course my boys couldn't wait to stick their fingers through the ascending aorta and pull on the valve tendons.

Wow--impressive. Glad the boys were so engaged in the dissection. Mimi
