In this inquiry activity, teams of students are challenged with engineering a greenhouse heat trap for use with exotic plants. The investigation requires thermometers, plastic wrap, and a shoebox for each team. Students graph data and determine the effectiveness of their design. This activity is supported by a textbook chapter, Atmospheric Energy, part of the unit, Energy Flow, in Global Systems Science (GSS), an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand significant problems of global impact.
