This lesson helps students learn about the biosphere by making observations and using a dichotomous key.
This is an activity that was developed to give participants an understanding of the biosphere. In this one-hour long activity, participants learn about the biosphere by making observations and taking measurements. They will go outside and use a dichotomous key to investigate plants and land cover as an indication of amount of water in the biosphere. Students will use this qualitative data to understand how water is found in many places in the natural environment and how these places are connected in the water cycle. The data collection is based on protocols from the GLOBE program www.globe.gov.
The following lessons have been developed to teach students about local and global water issues. They are based on NASA’s Global Precipitation Measurement (GPM) Mission and an instructional module designed for Montgomery County Public Schools Outdoor Environmental Education Program (http://www.montgomeryschoolsmd.org/curriculum/outdoored/).
