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 is based on studies completed by undergraduate geoscience students working around the glaciers of Kongsfjord, Svalbard during the summer of 2014. It is intended as part of a larger unit on matter that covers atomic theory, atomic structure and the periodic table. Students connect authentic research to their classroom understanding of atoms while learning how this

It is intended as part of a larger Earth science unit that covers erosion, transport and deposition of sediment. Students connect authentic research to classroom investigations while learning how to interpret current data to understand
Students will review charts of day length to determine when the sun will set at Toolik Lake.
Objective
Students will learn the following:
* The sun is the major source of energy for phenomena on the earth's surface, such as growth of plants, winds, ocean currents, and the water cycle.
* Seasons result from variations in the
