TEK TALKS is a series of webinars that was developed to foster understanding among scientists in regard to working with Indigenous People. View archived lectures and/or sign up for future lectures through the website.
Coring trees is a way of learning about trees without cutting them down. When a tree is cored, the rings are examined to learn about the history and growth of a tree. In this lesson students will participate in a hands-on activity to help them investigate what information can be gained by studying and comparing tree core samples collected
Students will explain, both orally and in writing, a diagram used to illustrate a food web.
Objectives
Students will learn how language is used to communicate and is required to impart knowledge and sustain a healthy, traditional community in a modern world.
Students will learn strategies for communicating complex ideas to an audience.
Students discover how different organisms that live in the Arctic depend on each other and what might happen to the food web if one or more organisms disappears from it. Students will build an arctic food web.
Objectives
Students will learn that organisms are part of a global food web and linked to each other and their
People have lived in the Arctic for many millennia, developing skills, strategies, and community knowledge to survive polar conditions. The attached flyer, produced by the International Polar Year (IPY) Programme Office, summarizes some of the present issues of concern for residents of the Arctic, including issues of health, food security, community well-being, resource development, and place in the global economy
This is a food web activity that I developed after my spring 2006 TREC expedition on board the USCGC Healy, for 30 days in the Bering Sea. It is a set of lessons that include setting the context with a map activity, researching the organisms in, on, and around the Bering Sea, reading an article or book on connections between
As the homepage of the website describes, "The beauty of the Arctic, its precious and fragile nature, its critical role in maintaining a stable climate for the planet, and the rapid rate of change that is occurring there must all be conveyed to the general public. Here, through digital story telling, we put a human face on science, life, societies
Students will use marshmallows to simulate toxins in the environment. Concentrations of these toxins will be modeled and calculated as they bioaccumulate up the food chain. Methylmercury and POPs are substances that bioaccumulate in the Arctic food chain. OASIS scientists studied these in Barrow, Alaska.

This lesson answers the question: How does ice floating on the ocean act as it melts?
Objective
* Students will learn about temperature, salinity and their effect on density.
* Students will learn that ocean currents are caused by differences in densities as a result of temperature and salinity. These differences allow ocean currents to circulate water
