I. Contact your local American Cancer Society. The ACS has kits that are designed for use by almost anyone to teach school-aged people the hazards of smoking. The kits are divided into grade levels ranging from grades 3-12. Organize groups of 3-4 people per group per grade level and give the appropriate materials from the kits to each group. The junior and senior high school packets have masters for overhead projectors as well as handouts.
All levels have instruction booklets.
Get a list of the principals of each of the schools in your area. Contact each school at the beginning of the school year. Many schools have a master calendar on which you need to be placed. Many schools teach about the respiratory system and want you to come on during that time. However, if your group is good, then that can work in your favor.
