Here are two clips that explain Jainism. One is below and the other comes from PBS RELIGION & ETHICS NEWSWEEKLY that you can see here.
Here is a pdf of a chapter from William Dalrymple's book, Nine Lives, called "A Nun's Tale." It's a moving story about a Jain nun who loses a close friend to cancer and questions her faith's insisentence on impermnance. Here is a NY Times review which is a bit shorter and maybe easier for students.
Here's a webquest about Jainism based on the Jain exhibit at the Victoria and Albert Museum. The lin only works if you're in the FCPS system.
