Students put a heart back together instead of cutting it apart and MASTER the pattern and purpose of blood flow through the heart and lungs. Students cut out a paper heart, cut holes in it for attachment of major arteries and veins, and then attach all of the significant blood vessels and the lungs. As they figure out the puzzle, label, draw arrows to show the flow direction, add CO2 or O2 molecules, and color it blue and red, they visualize how it works. I call this an "un-dissection" and find that it is MUCH better for increasing their understanding than an actual heart dissection!
