Melissa Lau spent a month in the tundra ecosystem gathering data using a device called a Greenseeker. This device measures exactly how green a plant is by calculating its NDVI or Normalized Difference Vegetation Index. In this lesson, students will explore light waves, how they interact with plants, and find out how green is green.
The objectives of this lesson are:
* Students will know that climate change is happening most quickly in Arctic regions.
* Students will know that a warming climate is causing permafrost to thaw.
* Students will know that thawing permafrost is impacting infrastructure in Alaska, including roads and buildings.
* Students will design an engineering solution to create stable
Students will use a model to explore the relationships between sunlight and release of carbon dioxide (CO2) from thawing Arctic watersheds.
After studying the carbon cycle, students are asked to reflect on how natural phenomena – thawing of permafrost, interactions of soil microbes on dissolved carbon, and amount of sunlight – interconnect and influence the release of CO2
This lesson introduces students to krill, their importance in ocean ecosystems, and the physical structures that make up the krill body. The students will then use the principles of a "floater" species and design their own krill, hopefully having a class competition to see who can build a better krill.
Objectives
Students will understand the importance of krill in
Rings of life is a comparative lesson allowing students to investigate growth rings in walleye Pollock from the Bering Sea and Ponderosa Pine trees.
Objectives
Students will be able to compare and contrast growth rings on fish and trees, showing just one of the tools scientists use to monitor the health of different ecosystems. Students will also be able
The following PowerPoint presentation is part of an anticipatory set used to excite and introduce students to the many wonders of the Bering Sea. The PowerPoint is to be presented at the beginning of a unit about the Bering Sea.
Objectives
At the start of a unit on the Bering Sea this PowerPoint video presentation will engage
Students will develop an understanding of what it takes to interview scientists, and take the corresponding data and reformat it into an electronic medium.
Objective
Students will be able to write questions to scientists in the field, interview, take the data collected, and convert to an electronic format including MP3 clips and post to the Internet.
