Olivia+Sheep+Heart+Dissection

=Sheep Heart Dissection =

The sheep heart dissection was our second big dissection of the year (the first was the sheep brain). In this dissection, rather than spending most of our time waiting for Mr. Orr to come check our identifications, we took a picture of each feature and sent those pictures to his flickr account, properly labeled. At right, you can see the aortic semilunar valve. This valve is important for the flow of blood in and out of the heart. We really felt a lot of freedom with this project seeing as the identifying was up to us, as was figuring out how to work our cell phones to send in pictures, but we caught on. During class that day, Mr. Dunning brought in a group of adults admiring our science department. They chose a good day, sheep hearts were out and one man on the tour even asked us about having our phones out. He seemed very impressed that our teacher found a way to tie in something that many teenagers feel they can't live without, their cell phones, to a scientific activity about sheep hearts.
