Year 9 Sheep Heart Dissections

My year 9 classes finally got the chance to dissect pig and sheep hearts. 

9KEm and 9TMn got to do it as part of the new 'Me, Myself and My Environment' unit, and even though we have run out of time to finish that unit we didn't want 9PLa, 9PTt or 9RTd missing out on this fun and practical learning experience!

We had a look at the aorta, as well as the left and right atria, ventricles and chordae tendineae.

Students were really good at remembering which side of the heart is bigger and has thicker walls of muscle, and explaining WHY!  (The left side is bigger and more muscular because it pumps blood around the whole body, while the right side only pumps blood out to the lungs and back).

Here is the video of their dissections - listen carefully as James' from 9RTd gives an explanation halfway through:
