Scientists are studying the effect of climate change on vegetation in the Alaskan tundra. In this activity, students will analyze data collected from control plots and plots with Open Top Chambers (OTC's) over them. An open-top chamber is like a tiny greenhouse that increases the temperature in a vegetation plot an average of 2-3 degrees, simulating the effects of
This activity was prepared by David Walker (LASA High School) and Rose Cory (University of Michigan), based on work conducted at Toolik Field Station in Alaska. The purpose is to introduce students to Van Krevelen diagrams, which are used to interpret results of high resolution mass spectrometry and characterize the compound classes present in complex organic mixtures. Students will
