This lesson investigates the correlation between the rate of cellular respiration and metabolic rate of Weddell seal pups. Students will collect data of their personal oxygen consumption rate at rest and during exercise, and evaluate how collecting oxygen data can be used to calculate metabolic rate. Students will comprehend that heat is a product of the reaction of cellular
This lesson plan is designed to teach students about the importance of the benthic community in the shallow portions of the Arctic and how climate change may affect their respiration. One of the dominant benthic animals in the Arctic, the bivalve Macoma sp., is an important food source for higher trophic level organisms such as walrus and Spectacled Eiders
This is a STEM-based lesson that can be taught in class or online. Students will analyze Weddell seal pup growth data, collected by the Growing Up on Ice, B-030, research team. To use this lesson virtually, include the data cards and have students either construct graphs and upload an image of their graph, or construct a graph and share
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 lesson plan is designed to teach students about benthic biodiversity in the Arctic by analyzing data from the Distributed Biological Observatory (DBO). Although you can’t see them from the surface, the organisms found on the ocean floor are important indicators of ecosystem health and provide information about productivity. Students will explore sites throughout the Bering and Chukchi Seas
This lesson investigates the effects of different insulators (fur and blubber) on maintaining the body temperature of polar animals. Water balloons filled with warm water simulate the marine mammal. The blubber insulator will be simulated by covering the balloon in vegetable shortening. The fur insulator will be simulated by placing another balloon over the “marine mammal” and adding an
I am honored that I get to share my field experience with so many individuals. Not a day has gone by since my return that I have not had a question about my expedition and I love the range of questions I receive. Honestly, I may have never really considered how many people are in
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
