This curriculum consists of a one-week course of study designed to introduce K-3 students to (or increase their awareness of) toxic substances commonly found in the home. It includes an introduction/conceptual framework and four learning activities for four concept areas (and an optional word puzzle). Each activity includes a statement of purpose, a list of materials needed (with overhead projector masters and ready-to-duplicate student handouts provided), an objectives statement, advice on classroom preparation and instructional strategies, and evaluation suggestions. The concepts fostered focus on the routine use of toxics, why toxics must be use and stored safely, how toxics may be mistaken for food items, and disposal concerns. The appendices include an annotated list of resource materials, a list of state hazardous and solid waste agencies containing additional information on household toxics and safety precautions, a chart of household products causing indoor air pollution, a resource sheet on chemical hazards in the arts, a list of environmental/health and safety curricula, a chart of first aid tips for poisoning, and a question and answer sheet on specific toxic "incidents."
