Researcher Elizabeth Webb discusses her experiences working in the field with a PolarTREC teacher. She worked with John Wood in 2011 and 2012, and Tom Lane in 2013, on the Carbon Balance in Warming and Drying Tundra expedition near Healy, Alaska. (She primarily discusses her time with John Wood since this interview was taken in 2013, before Tom Lane's expedition.)
Soil decomposers, such as some bacteria and fungi, obtain energy needed for life from dead and decomposing plant and animal remains, known as soil organic matter. Soil organic matter is important to local ecosystems because it affects soil structure, regulates soil moisture and temperature, and provides energy and nutrients to soil organisms. It is also important globally, because
This one hour event features the GLOBE Africa and Globe Seasons and Biomes expedition to Mt. Kilimanjaro, Africa. Students and teachers that are on the expedition explain the different biomes they pass through on their way up to the summit of Mt. Kilimanjaro.
This one hour event features the expedition with the GLOBE Africa and GLOBE Seasons and Biomes program to Mt. Kilimanjaro, Africa. Dr. Kenji Yoshikawa,from the University of Alaska Fairbanks, presents on the permafrost and hydrology features of Mt. Kilimanjaro while he is on the mountain.
Dayton's News Program, Fox 45 in the Morning, talks with teacher Chantelle Rose directly from the Arctic about her oceanographic PolarTREC expedition and follow-up involvement with the 2012 Arctic Ocean Ecosystem Workshop in Barrow, Alaska.
Students decorate polysterene cups later to be submerged in the ocean. Subsequent activities have students consider the effects of water pressure and depth with respect to their cups.
Objective
Students will determine mass and volume of a styrofoam cup. They will calculate the density and research the depth of the Bering, Beaufort and Chukchi Seas. They will
In this one hour presentation, PolarTREC teacher John Wood explains the scientific work in the Carbon Balance in Warming and Drying Tundra expedition from Healy, Alaska.
Students chose a research project, from one of seven suggested projects, to complete in class with a partner. Upon completion they will present their information to the class.
Objectives
Students will present a scientifically accurate project on a topic related to the PolarTREC Winter Sampling expedition.
Lesson Preparation
Introduce students to the PolarTREC website. Any expedition could be selected
This one hour presentation is part of the C-ISE Physical Science professional development course. Elizabeth Webb in Healy, Alaska explains the carbon balance in warming and drying tundra.
Results from PolarTREC teacher Chantelle Rose's research cruise to the Bering, Chukchi and Beaufort seas surprise scientists and may have implications for climate modeling. Read more about the tenacity of life forms living off the coast of Alaska from this National Science Foundation press release.
