Heart dissection classes are amongst the hardest and most daunting, partly because its difficult, its new with new tools and most of all because our boys have a terrible habit of lying about how squeamish they really are!
This single worksheet and one heart between two students is all you need for a top notch quality learning lesson, no slides required!
The worksheet shows a butterfly style heart dissection, so called as the front and back are seperated and if performed correctly resembles a gruesome butterfly, you will have access to each blood vessel, all valves and have a ver identifiable structure you can reference to in workbooks.
Tips for best practice
-Practice by yourself first!
-Show each step by webcam onto the big screen, or even better Discord can stream to multiple ipads/tablets on each desk.
-Make it a competion, biggest bloodclot found, best dissection, most features correctly identified etc.
-Let them mess it up, but show them their success (oh that incision is in the wrong place, but you just found the Aorta!!!)
This is hand drawn, very impressive to see so much to be gotten out of a lambs heart, I can see how you've called it 'ultimate' as I don't think I'll need anything else for my lesson. Is there any tips you have for doing the dissection, I've personally always struggled.

Sure thing! I love a heart dissection, it's one of the few times we're not answering to the scheme of work and we're learning for the sake of learning, whether or not its all the vessels and valves or simply that we can do it.
So some tips
1. Prepare as much as possible, set out all the equipment, reset a very strict set of expectations and almost tell students step by step what you're going to be doing before you do it.
2. Have an exit plan, some will not want to take part, most will, some will get in over their head and a few will act up to avoid participation, make sure you have something else for them to go do, as you're running a dissection, that something else should be under another teachers supervision.
3. Demonstrate and model it first, using a webcam to show on the board is best, but gathering them around to watch as you do the dissection first is essential. Always keep a spare heart!
4. Once you've clearly defined their boundries and expectations... hard as it is... let go... let them explore. Their measure of success is up to them, just make sure you're lavishing praise and suggesting they all become doctors because of how well they're doing, some might actually do it!
5. The value doesn't end when you're finished, its a little gross but walking through the school to the canteen bins with a bag of offal and praising kids for their heart dissections adds wholesale value to your reputation, the schools experiences and creates a serious buzz for science long after you've thrown that bag in the bin.
Honestly, we may not be actively pinging the specification with a dissection but those boring parts and behavior management go down a lot easier when everyone remembers that time we did a dissection!
Good luck and have fun!!!
