This lesson was created by Rebecca Harris after being a part of the Arctic Glacial Lakes PolarTREC Expedition. She was inspired by how important suspended sediment, something so often overlooked by non scientists, was for developing paleoclimate models as well as ecosystems. Students will observe a watershed or a model of a watershed to make predictions about what might
This lesson plan was created by after being a part of the Arctic Glacial Lakes PolarTREC Expedition. I was inspired by the massive amount of data collected over the course of the research project and the complexity of hydrology in glaciated and non-glaciated basins in the Brooks Range of Alaska. Students will work together to make hypotheses about patterns
In August 2017, I spent two weeks at Lake Peters, in the Arctic National Wildlife Refuge. My team included Darrell Kaufman, project co-PI and Professor in the School of Earth Sciences & Environmental Sustainability, Ellie Broadman, graduate student and PolarTREC researcher, and graduate student Chris Benson, all of Northern Arizona University. Our research was part of the final
Teacher Rebecca Harris and Researcher Ellie Broadman discuss field work, weather and life at the remote field site near Lake Peters, Alaska as part of the Arctic Glacial Lakes Expedition. This live event was broadcast from Kaktovik, Alaska.
An article describing Kevin Anchukaitis' work at the Lamont Doherty Earth Observatory. Tree rings embody a record of climate change going back thousands of years, and they grow on every continent except Antarctica. “They let us reconstruct climate around the world, in both space and time."
Humans are creative. They try to solve problems in original ways. For example, some scientists are thinking of ways to decrease the amount of greenhouse gases in the air. Other scientists are thinking of ways to limit the amount of sun that reaches Earth so that the Earth won’t get so warm. Like most ideas, there are pros (good
Textbooks say that carbon dioxide is a greenhouse gas and can make earth's climate hotter. Try this lab to see if carbon dioxide gas can really act like a greenhouse.
Objectives
Students should be able to make a hypothesis, perform an experiment, analyze data and write a conclusion based on the evidence from their experiment.
Article describing PolarTREC teacher Susy Ellison's recent expeditions to Alaska to take part in a tree ring study in the Arctic National Wildlife Refuge and an archaeological expedition in Kivalina.
