In this article, a public high school teacher in Arkansas reports that teachers are not allowed to use the "e" word (meaning "evolution").  He also says:

“I am instructed NOT to use hard numbers when telling kids how old rocks are. I am supposed to say that these rocks are VERY VERY OLD … but I am NOT to say that these rocks are thought to be about 300 million years old.”

Arkansas is ranked 37 in public education rankings, but it clearly has its sites set on number 50.

The video clip, narrated by opera star Joan Sutherland, featured sock puppets singing in French from the 16th-century morality tale.

Several parents complained that the video, which Waggoner got from the school library, contained references to abortion and Satan worship.

Interesting.  Especially when you read this:

Faust, a legendary character in music and literature, dates back to a medieval morality tale of a deeply depressed man who sells his soul to the devil.

In all versions of the Faust story, the man obtains power and knowledge, but suffers dire and eternal consequences.

Early Christian teachers used the story to show the horrors that befall those who give in to the devil’s temptations.  Source: Encyclopaedia Britannica
