Science Buddies: Project Ideas: Green Detergents Less Toxic Than Conventional?

In this science fair project, test the toxicity of "green" and conventional detergents, using worms as test organisms. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a section on terms, concepts, and questions, bibliography, list of materials and equipment, experimental procedure, suggestions on how to vary the experiment, plus a focus on the sort of careers this experiment might relate to.
