I am working on a beef unit that a sub can teach while I am gone. Now, I don't know about you all, but I cant trust my subs to take roll most of the time so I need something that is fool proof for them to teach while I am gone for a week. I am wrapping up my beef unit with the Temple Grandin movie. I want my kids to do design a beef facility using the basics of Dr. Grandin's designs. Anybody have something that would work for this?
