Environmental Teaching in the Classroom

The Social Studies Department provides instruction on environment issues. Students develop fundamental understanding of society’s interplay with the natural environment on local, regional and global scales through the study of concepts related to physical, economic, cultural, urban, political, historical and environmental geography. Examples of such study include activities on global warming, the polar regions, recycling, energy consumption, nuclear dump sites, degradations of the Rainforests, “Green” initiatives, pollution in China, India’s “Green Revolution”, etc.A variety of resources are used to teach environmental related issues including field trips, newspapers/magazines, National Geographic issues, film (The Day After Tomorrow), National Public Radio reports on climate, demographic data, CNN series on Planet in Peril, etc.

Or students may enroll in International Baccalaureate Environmental Systems, a rigorous study of environmental issues and problems caused by our use of the natural world.

Outdoor Lab

Part of the Arlington Public Schools’ curriculum is student visits to Phoebe Hall Knipling Outdoor Laboratory located in Fauquier County near Gainesville, Virginia. This 210 acre tract of land is owned by the Arlington Outdoor Education Association and made available to the school system as an outdoor science laboratory. Student groups are scheduled for day or overnight visits for specific learning activities. Programs conducted at the laboratory are related to the K-12 science curriculum as well as other curriculum areas. Students learn to observe in this natural environment, generalize about the interrelationships within the environment, and develop environmental awareness. Students learn how their decisions and behavior affect other living things. As they acquire knowledge and understanding from and about the environment, students develop competence in evaluating alternatives for using and managing resources. Approximately 9,000 Arlington Public School students visit the Outdoor Lab each year.
