This video was posted to YouTube last April, but has only recently gone viral. It shows a science teacher calmly trying to explain a concept 4th graders have no trouble with to her state senator. Sen. Mike Walsworth asks if there are any concrete examples of evolution that could be taught in the classroom. The teacher patiently responds that yes, there are. She is used to speaking slowly and in small words for the kids in the back of the classroom, so this is not that difficult for her.
