This free, standards-based, online publication, developed for middle school science teachers, explores the water cycle--a series of steps involving changing states of matter through the processes of evaporation, transpiration, condensation, and precipitation. In middle school, students can begin to investigate the chemical and physical properties of water that enable it to behave in ways necessary for the water cycle to happen.
