Lake El'gygytgyn (67.5º N, 172º E) is one of the best preserved large asteroid impact craters on earth. In the winter of 2009, I joined an international science team and traveled to the frozen arctic lake to drill and extract lake sediments to study climate change as well as sample the rocks that were changed when the crater
The sediment in Lake El'gygytgyn, (pronounced EL-ge-GIT-gin) located in NE Siberia, holds one of the longest records of climate change anywhere in the continental Arctic. How does sediment (clay and mud) tell us something about past climate? Proxy data! By studying the microfossils of diatoms and pollen in the sediment, we can re-construct the lake environment millions of
Marine debris is primarily human-created trash found floating in the ocean. It can cause serious health problems for animals in a marine ecosystem. Students will gain first hand knowledge about the types of garbage found in the ocean by participating in a waste clean up tally.
Objective
Students will collect marine debris or land-based garbage in order
Students will engage in a hands-on activity to build their own plankton nets and help them understand how scientists use the nets to study changes in the ocean ecosystem.
Objective
Students will gain an understanding of how scientists use plankton nets and microscopes to study changes in the ocean ecosystem.
Students are asked to predict what will happen to styrofoam objects lowered down to the bottom of the Bering Sea. Students make the appropriate calculations related to the actual experiment which took place on Maggie Prevenas' PolarTREC expedition.
Objective
Students will make hypotheses and calculations regarding deep sea experiments that took place in the Bering Sea on
The Aleutian Islands, between Alaska and Siberia, have earned the name "Cradle of the Storms" due to their wild weather. Students will view a two-part series about the Aleutian islands and answer questions related to the film.
Objective
Students will learn about the Aleutian Island chain in Alaska and answer questions to reinforce learning.
This activity is meant to help students authentically learn the scientific method through comparing and contrasting oral history (storytelling) as a way to pass along information and solve problems with the scientific method. It also helps connect the students' cultural identity with the curriculum.
Objective
Compare and contrast oral history traditions to the scientific method as a
Students will sort organisms found in the Bering Sea into food chains and gain an awareness of the flow of energy and nutrients in the Bering Sea Ecosystem.
Objective
Students learn about the different organisms that live in Alaskan waters by playing the Fabulous Food Chain Game. In playing the game, they become aware of the flow of energy
Teacher leads class through collaborative lesson. Language Arts, Social Studies and Science Book "Good-Bye My Island". Chapters of the 16 chapter book are read, summarized and taught by teams of students.
Objective
General Learning Outcomes:
Academic Achiever-by reading the assigned chapter and summarizing the important points.
Community Contributor-by giving information to the rest of the class so
Much like an owl pellet, a bolus is all the indigestible material that is "thrown up" by an albatross. Shaped like a fat cigar, one can dissect a bolus to assess the health of our ocean, the foraging ground for thousands of albatross trying to gather enough food to feed their hungry chicks.
