I do a unit on anti-bullying each year and during this unit I show the film Bowling for Columbine. Included in this packet are:
Extensive Study Guide Questions for the Film (43 Questions)
A 20 question study guide (Depending upon the level of the class you might want to use the shorter study guide.)
Two articles that relate to the school shooting.
A list of 16 research topics that relate to the film. (You could do this before or after the film. I do it after the film.)
Two poems written about Columbine High School
I've used this movie with different levels of high school students many times over the years. You can talk about bullying, gun control and the recent school shooting at Sandy Hook.
