The American Chemical Society's National Chemistry Week (NCW) program will be celebrating its 20th anniversary in 2007. We will discuss the past, present and future of NCW, ways to incorporate it in the high school classroom, and engaging the public. Chemists Celebrate Earth Day, a newer program, was created to coincide with an already long-running celebration, Earth Day. Learn about the possibilities for this outreach activity as well and tips, techniques and the resources that exist for public outreach.
