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
From July 19, 2022, to August 15, 2022, I participated in the Harmful Algal Blooms in Arctic Waters research cruise on the R/V Norseman II. The Chief Scientist was Dr. Robert Pickart from Woods Hole Oceanographic Institution (WHOI), and the research team included scientists from WHOI, Oregon State University, the Florida Fish and Wildlife Conservation
This event with teacher Rebecca Siegel was broadcast live on 4 August 2022 from the Norseman II in Arctic waters. Rebecca is joined by team members from Woods Hole Oceanographic Institute working on Harmful Algal Blooms in Arctic Waters.

Scientists in Siberia are seeing trends of more severe and widespread wildfires. By observing and measuring larch forests, they are trying to understand how the forests are changing. What do these trees need to survive? Are they getting what they need? Students will plant lodgepole pine seeds providing some with all the necessary components for survival and others missing
Scientists in Siberia are seeing trends of more severe and widespread wildfires. Larch seeds are dispersed by wind. Experimentation is currently underway to determine distances larch seeds can disperse from viable, mature larch trees. Students will explore how various types of seeds are dispersed to get what they need to survive.
Timeframe: 90 minutes
Grade: K-2
Students will learn to:
* Observe and record weather patterns
* Process data by creating graphs/charts
* Compare actual weather data from the Siberian Arctic to local weather patterns, draw conclusions and make future predictions concerning weather patterns.
Big Idea
Why do people need to track weather over time?
Lesson Preparation
You will need a thermometer, tracking calendar, and
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
The work of professor Bryon Crump, graduate student Natasha Christman, and PolarTREC teacher David Walker is highlighted in the weekly newsletter of the Oregon State University College of Earth, Ocean, and Atmospheric Sciences (On the Horizon).
