Explanation:
INTRO: HEART DISSECTION
Have a heart!
The original pump that is the drumbeat of our lives is an amazing structure. You've seen them on holiday cards, but now it's time for the real thing. A heart dissection is a fascinating experience that is at the core of our circulatory system, and our body as a whole. There our other dissection photos out there, but I wanted to make a clear walkthrough for teachers and students who are doing it.

Let's go!
A NOTE ON DISSECTIONS:
Dissecting animal organisms is a tricky subject which ultimately some will object to and that's okay. For us, we believe that with careful scientific exploration of animals who were treated in humane ways, we can learn and teach our students to be greater stewards of the environment, and especially toward the species they just learned about. There will always be some students who wish not to do a dissection, and we always allow whatever level of participation they choose in these experiences. Many prefer to just watch. Many of those eventually join in. But whatever it is, feel it out with your classroom or audience.
