This is the lab sheet/guide I created to dissect owl pellets. It has simplified instructions, a bone counting chart, post-lab questions about body systems, and a mouse skeleton on the back page.Some pellets contain small birds, but I've only ever gotten mice. I did this lab during an anatomy unit to prepare for mammal dissections, but this lab would be great during an ecosystem unit- just change the post-lab questions to ask about food chains, consumers, etc.
