An Idaho biology teacher is facing possible disciplinary action after killing and skinning a rabbit in class to show students where their food comes from.

Nampa School District spokeswoman Allison Westfall says the teacher killed the rabbit in front of 16 students by snapping its neck on Nov. 6 at Columbia High School.

The rabbit was then skinned and cut up in front of the 10th graders.

Westfall says the demonstration isn't part of the biology curriculum.

She says students who didn't want to view the lesson were allowed to leave ahead of time.

The teacher's name hasn't been released.
