Students will conduct a demonstration that will help them gain a better understanding of the water cycle and runoff in a watershed. They will be able to replicate arctic and non-arctic watersheds by varying the size of the watershed. They will be able to visualize the difference in runoff by creating hydrographs of these different locations.
Students will investigate the breadth and depth of science taking place in the Polar Regions by reading and learning about one PolarTREC expedition and sharing it with the class.
Objectives
* To expose students to the wide variety of science happening in the Polar Regions
* To help students understand the process of science by examining one
This one hour event by Melissa Barker explains the research being done at Toolik Field Station, Alaska on nutrient transport in arctic watersheds. She is joined by team member Dr. Sarah Godsey.
View sequential still images of thermokarst (thawed permafrost) at Horn Lake in northern Alaska during the summer of 2010. The video was made by researchers studying the responses of Arctic landscapes to permafrost degradation.
PolarTREC teacher Melissa Barker, a high school biology and environmental science teacher, shares her thoughts about her upcoming expedition to Toolik Lake, Alaska where she will learn about changes in water and nutrient cycles in the arctic tundra. The external link provided includes a video interview with Melissa at her school.
PolarTREC Teacher Melissa Barker is a feature story for her school in Colorado. She is heading into the field with Dr. Tamara Harms to study Arctic watershed systems.
In this lesson students research scientific field expeditions and learn what it is like working in the field. Students are able to ask questions of the research team as part of their project. Students then share what they have learned with their classmates.
Objective
1. Students understand what really goes on in the field during a scientific study.
2
An important science skill that needs to be developed is asking significant questions that advance knowledge. This activity helps students to understand the difference between significant and trivial questions.
Objective
Students should be able to distinguish between significant questions that advance knowledge and trivial questions.
Procedure
1. Have the students define significant question and trivial questions in a
Finish newspaper, Maaseudun Tulevaisuus, published this article about Micheal Wing and the archaeology team working in Yli-Li. Attached is the translated article (by Reija Shnoro).
In this activity, students diagram the hydrologic cycle. Most of the concepts will already be familiar to middle and high school students, but this activity is a good way to prepare for making the far more challenging carbon cycle and energy NON-cycle diagrams.
Objective
* Students understand that the total amount of water on Earth is constant
