Three eighth-grade students have been expelled from their middle school for showing students a pornographic DVD in the classroom when their teacher wasn't watching.

The Bay Minette Middle School students put the DVD into the player while their teacher was busy grading papers and working on a computer, said the assistant superintendent for Baldwin County Schools, Terry Knight.

The students projected the DVD onto a screen where an educational video had been playing, Knight said.

They were found out when another student told the teacher.

The students and their parents can appeal the expulsion or try to get the students to finish the rest of the year at an alternative school, Knight said.
