There was a TED talk recently about vultures. I think educators might be interested in seeing it for their own background research. It’s only a little over six minutes long. You’ll want to look it over first before deciding whether it is appropriate for your elementary school students. The humor at the beginning would probably raise more sidetracking questions than it would actual vulture inquiry. So take a look and perhaps start two minutes twenty seconds in (2:20). Because the rest of it is good stuff for older elementary, middle school, and high school. There are quite a few carcasses involved and it is frank in environmental threats to vultures worldwide.
