Are there alternatives to dissections?

What about dissections.  I feel strongly kids should dissect preserved specimens, not road kill or pets.  But, some kids will NOT dissect under any circumstances to the extent they won't be party to a class that does dissections, even if they are exempt.  In other cases, families may not be able to afford the specimens or justify the expense for one child.  So what are the alternatives? If the issue is your daughter is a strict vegan, this synthetic shark lab from Smithsonian can be reused!  I was pricing preserved shark specimens and saw this one on Amazon.  The church's insurance policy prohibits any experiments on site.  (We dissect in my garage at home.)  I wanted to see the quality of this synthetic shark and the Bio class could test it and then set it up again for the little kids in the afternoon.  In fact,  the Bio kids are participating in an alternative assessment as they guide the little kids through the dissection. Slick, right?  Yes, Virtual dissections  abound.  Use those sponsored by textbook publishers or located at science sites such as Biology Corner.  How was the shark?  The girls carefully followed direction to create the shark specimen.  After 15 minutes it was ready.  The dissection packet enclosed had terrific details about shark anatomy.  The Smithsonian Shark Lab (Ebay has one, too.) isn't cheap; it is reusable and basically a toy, which can be dissected anywhere.  The Smithsonian also has a frog dissection kit.  If your facility limits experiments the frog and shark kits, with owl pellet dissections, supplemented with virtual dissections would provide a decent alternative to preserved specimens, especially for teens strongly opposed.  These kits are nice for elementary aged kids, too, who may not be ready for the real deal.
