In this video segment adapted from NOVA, dramatic footage of avalanches and animations of ice crystals illustrate how a layer of weakly-bonded snow can contribute to a devastating avalanche.

This video segment adapted from KET's Where the River Bends demonstrates how climate change and glacier movement during the Ice Ages destroyed the old Teays River and created the Ohio River, Kentucky's northern border.

Learn how the Hawaiian Islands were formed by a geothermal hotspot and resulting volcanic activity in this video segment from Nature.

In this video segment adapted from the National Film Board of Canada, learn how the Inuit people have used their traditional knowledge to understand and adapt to changes in their Arctic environment, particularly when hunting and navigating the landscape.

This lesson plan, provided by the International Society for Technology in Education (ISTE), encourages students to evaluate literature in a variety of multimedia formats and answer the question, "Who Am I?," Students are then asked to create their own multimedia portfolios and Web pages to reflect who they are. L.11-12.3 Language Functions/Style

This interactive image of an oxygen-binding curve for hemoglobin demonstrates
how changes in the concentration of carbon dioxide impact the environmental
pH and the structure of the hemoglobin protein, thereby altering its ability to
bind oxygen.

Learn where diamonds originate and how inclusions trapped within diamonds help geologists determine their age in this video segment from Nature.

In this video segment adapted from NASA, astronomer Michelle Thaller introduces the world of infrared light and demonstrates how infrared cameras allow us to see more than what the naked eye can perceive.

The Molecular Structure chapter from "An Introduction to Chemistry" textbook discusses the formation of covalent bonds, drawing Lewis dot structures, and the resonance and molecular geometry of molecules. Many pictures and examples are helpful in understanding the information. Also, find a detailed chapter review with questions that check for comprehension.

The structure of the atom is uncovered in this interactive tutorial. Discover the different particles of the atom and learn their charges and how they can affect the overall atom.

This lesson focuses on torsion as a force acting upon structures. Students will have the opportunity to design something to withstand this force.

In this video from Science City, Kerri-Ann Richard, an environmental engineer, describes how she became interested in the field and why it is important to clean up the environment by removing contaminants from soil and ground water.

Great learning exercises to check your understanding of the kidneys. Complete this problem set and if you miss an answer you are taken to a tutorial that is very useful. This is a good site to use for research as well as checking for understanding.

In this Nature video, follow geologists as they retrieve samples from a fresh batch of Kilauea's molten lava.

In this video segment adapted from NOVA, scientist Mike Garcia draws lava samples at the foot of the active Kilauea volcano to see if it is related to its neighboring volcano, Mauna Loa.

Provides a technical discussion of the anatomy and physiology involved in the receptors associated with the sense of smell. Includes pictures and formulas.

Provides a very basic look at the anatomy of a mollusk including the proposed anatomy of what the mollusc ancestor probably looked like. Hyperlinks to individual animals in the mollusk group.

In this activity, students design an innovative human shelter that is inspired and informed by an animal structure. Each group is assigned an animal class, and they gather information about shelters used by the animals in that class. After researching the topic and brainstorming ideas, students build small prototypes (models) of the structures. Finally, they present their products, explaining what attribute of the animal structure influenced their design.

In this video segment adapted from the Alaska Native Heritage Center, discover the connections between Alaska Native subsistence culture and the natural cycle of the seasons.

This resources offers a framework for the study of this ever illusive and beguiling topic which goes to the very heart of positivist efforts to understand social behavior.
