This is an outline I've used for a project on illegal drugs. The purpose of this project is to teach students about the consequences and reality of drug use. This project has students pick a drug and research its production,composition, history, uses, side effects, related laws, etc.
This project covers many cross curricular competencies and can be used in many different classrooms (or team taught!). It covers themes found in English Language Arts, Physical Education and Ethics and Religious Culture. It could even be used in a science class.
