148 – Owl Pellets

Once upon a time our system decided that science kids needed to have unit by unit performance assessments that demonstrated learning outside of a traditional test. For our first unit (Ecology) in honors biology the owl pellet is the featured choice. I tried to revamp the lab this year for honors as a niche characterization derived from the pellet that incorporates energy calculations and trophic level predictions. Better than just picking bones out of a pellet. At least I think so. So, today…kids picked bones out of a pellet. They will glue these bones on a “bone card” and ID the anatomy of the prey. Fro here, we will use class data to predict the energy budget for the owl and the trophic system of the area in which they live.

In AP biology I gave the first of 4 30-day summative tests. Basically 26 multiple choice and 2 short answer questions.

Tomorrow I AP it is on to speciation and one of my favorite activities: Lozos Lizards!
