Water in the Biosphere

Water is essential to Earth's living system, the biosphere. In this lesson, students determine the types of living things within an outdoor study site, use a taxonomic key to determine the predominant land cover type of their site, then predict the amount of water present. Data collection is based on protocols from the GLOBE program. This activity uses the 5E instructional model and is part of the "Survivor Earth" series of one-hour lessons.
