The purpose of this resource is to familiarize students with the importance of perspective and various scales of remotely sensed data. Students create a 3-D model of an area and develop a classification system for the landforms in their model. The maps can then be used to answer certain questions about the environment.

The purpose of this resource is to familiarize students with modeling as it relates to remote sensing and digitized images. Students will use the symbolic map created in the beginning activity to produce a digitized image and begin to see why ground verification of satellite data is necessary.

This lesson guides a student inquiry into properties of the ocean's carbonate buffer system, and how changes in atmospheric carbon dioxide levels may affect ocean pH and biological organisms that depend on calcification.

This video adapted from KTOO explores the impact of oil contamination on the herring population of Prince William Sound, Alaska, in 1999, 10 years after the Exxon Valdez oil spill.

This hands-on activity will provide students with an understanding of the issues that surround environmental clean-up. Students will create their own oil spill, try different methods for cleaning it up, and then discuss the merits of each method in terms of effectiveness (cleanliness) and cost. They will be asked to put themselves in the place of both an environmental engineer and an oil company owner who are responsible for the clean-up.

This video segment adapted from NOVA follows the clean-up effort after the 1989 Exxon Valdez oil spill off the coast of Alaska. Also featured is a marsh where an oil spill occurred 20 years earlier; analysis suggests that environmental damage may last for decades.

This introductory video addresses key points as well as pros and cons of oil as an energy source for transportation.

This narrated slide show gives a brief overview of coral biology and how coral reefs are in danger from pollution, ocean temperature change, ocean acidification, and climate change. In addition, scientists discuss how taking cores from corals yields information on past changes in ocean temperature.

In this video segment adapted from the Yukon River Panel, visit fishing communities along the Yukon River and see how Alaska Native peoples exercise stewardship of salmon to ensure that it remains a central food source and cultural touchstone.

The purpose of this resource is to observe seasonal migration patterns, feeding habits, and nesting behavior of Ruby-throated Hummingbirds (Archilochus colubris) in North and Central America. All students will learn about hummingbird natural history and ecology. Students will learn how to identify and age male and female Ruby-throated Hummingbirds and to observe migration and feeding behavior. Students will learn how to make connections among hummingbird behavior and weather, climate, food availability, seasonality, photoperiod (day length), and other environmental factors.

Against the backdrop of the devastating 1930's Dust Bowl, this video segment adapted from Interactive NOVA profiles an organic farmer and the techniques he uses to conserve topsoil.

This 3-part interactive and virtual lab activity examines the life cycle of the sea urchin, and how the increasing acidity of the ocean affects their larval development.

This activity is a field investigation where students will make observations on a chosen location every two weeks for the period of one school year. They will record their observations using a digital camera and a nature journal.

This interactive diagram from the National Academy of Sciences shows how we rely on a variety of primary energy sources (solar, nuclear, hydro, wind, geothermal, natural gas, coal, biomass, oil) to supply energy to four end-use sectors (residential, commercial, industrial, and transportation). It also focuses on lost or degraded energy.

This activity is an introduction to setting up a composting worm bin in the classroom. It is part of a yearlong study on the interaction and influences that living system have on each other.

This peer-reviewed educational video explains human-caused climate change including the greenhouse effect. The role that greenhouse gases play in absorbing and re-emitting longwave radiation is illustrated. Information on how scientists know that the observed global warming is a result of human activities that burn fossil fuels is concisely explained.

In this field exploration, student teams (consisting of 3 students) will investigate whetherincandescent, fluorescent or a no light situation will attract the most nocturnal insects.

Have we overstepped Mother Earth's boundaries? What are the consequences? In this video segment adapted from Haskell Indian Nations University, hear a Native perspective on our relationship with the natural environment.

This article looks at the growing energy consumption from consumer electronics and the increases it may cause in greenhouse gases and global warming. The article appears in the free, online magazine Beyond Penguins and Polar Bears.
