This PowerPoint is a great overview of the Chernobyl nuclear disaster. A bell ringer on the topic, Simpsons tie-ins (pictures & video clip), a video link from PBS explaining the disaster, maps, pros & cons of nuclear energy, effects of the disaster, and discussion of nuclear energy in the United States are all included. The PowerPoint is not something the students passively observe, but there are several points throughout where participation is required. I have left teacher notes about each slide in the notes section of almost every page. If teaching about Chernobyl is one of your standards, you should definitely check this lesson out. You won't be disappointed. As always, this lesson is completely editable to meet your classroom needs.
