"Humans have become a geologic agent comparable to erosion and [volcanic] eruptions ..." Paul J. Crutzen, a Nobel Prize-winning atmospheric chemist. Using Landsat imagery, scholars create a grid showing land use type, such as urban,...

Attracted class members to an activity-packed journey through the science behind the invisible forces at work all around us. From jump rope generators to junkyard wars, there's never a dull moment when eighth grade physics scholars...

Scholars investigate levels of nitrogen dioxide in the Pacific Northwest by examining the role of nitrogen in air pollution and how remote sensing can be used to measure nitrogen levels. An Excel spreadsheet calculates the difference...

Students study a way to quantify the process of photosynthesis during a given time using the Elodea plant. They design a hypothesis that they test in the hands on activity. They compare the amounts of photosynthesis that occur during low...

Students determine how scientists measure pollutants in food and the environment. Students discover how scientists remove one material based on its physical properties. Students figure out how much of a pollutant is present after...

Students investigate carpooling and determine to what extent it occurs in their community for a carpool challenge. In groups, students create a survey then collect, calculate and record data to determine how much pollution could be...

Students explore number sense by completing a statistical analysis game in class. In this data graphing instructional activity, students utilize visual references such as colored cubes and tiles to map out the results of an experiment...

Students identify greenhouse gases. They explain why perfluorocarbons are a bad alternative to chlorofluorcarbons. They determine both the least and most influential greenhouse gases.
