It's as close as a key stroke. Just go to the Teacher's Corner on the Nuclear Regulatory Commission's Web site. In addition to a detailed lesson plan, you'll find explanatory graphics and ideas for classroom activities. The American Nuclear Society maintains a schedule, with sponsors and contact information, for workshops around the country. You'll find it on ANS' Web site in the Teachers' section.
ANS regularly updates the schedule, so check it often.
ANS also publishes a newsletter for teachers interested in nuclear sciences. It's in the Teachers' section. Both ANS and the Nuclear Regulatory Commission offer glossaries on their Web sites. See ANS' Resources section and NRC's Students' Corner . The Lawrence Berkley National Laboratory's ABC's of Nuclear Science includes nuclear science experiments.
