Research Scenario Part 2

For research, since the teacher claims they got it from the district website of approved lessons, I would look on that website for the powerpoint. I would then contact the district and ask and search for other related topics. I would search to see if it's against school reculations for a teacher to teach that. I'd research other districts and rules the school districts has maybe even the state has against teaching the subject. I'd research peoples opinions, arguments towards the subject to get their reason for the discussion. I'd research any events that relate to this one that has happened in the past.
