Prepare engaging weather lessons, from short topical units to year-long weather tracking projects. Basic factual material about weather patterns and such weather phenomena as thunderstorms, tornadoes, hurricanes, heat and cold waves, floods, and droughts, are covered along with such hot topics and issues as global warming, air pollution, acid deposition, and ozone depletion. Thorough, balanced, and comprehensive, the sourcebook serves equally well as a ready-reference and a planning tool.
