My friend and coworker Liz sent the kids these owl pellets to dissect. They are so cool! They are full of bones, and come with a little map to help you figure out what kind of animal it might be.
This is exactly the type of thing we like to do and the kids loved it!
I definitely recommend ordering some of these if you want a quick, pretty easy to clean up activity that isn’t as messy as frog dissection.
