How do we know what kind of phytoplankton are in the water? The Imaging FlowCytobot (IFCB) is a robot that scientists use to image phytoplankton in the water. One IFCB can take up to 30,000 pictures per hour! The IFCB can be used in the field to detect plankton blooms in real time. In this activity, students will practice

Feature story on David Walker's Carbon in the Arctic expedition and permafrost science in the Spring 2020 issue of The Classroom Teacher, the quarterly magazine of the Texas Classroom Teachers Association. Article begins on page 12.
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
This activity was prepared by David Walker (LASA High School) and Rose Cory (University of Michigan), based on work conducted during summer 2019 at Toolik Field Station in Alaska. The purpose is to expose students to photooxidation, one of the main pathways by which organic molecules in Arctic streams are oxidized into carbon dioxide. Different teas will be used

PolarTREC (Teachers and Researchers Exploring and Collaborating) is a program that pairs US educators with field research experiences in polar regions. The program is managed by the Arctic Research Consortium of the United States (ARCUS) and receives funding from the National Science Foundation (NSF) Office of Polar Programs. The long-term vision of PolarTREC is "to create
