This video adapted from Texas Parks and Wildlife Department describes how humans are helping restore safe nesting grounds for the critically endangered Kemp's ridley sea turtle to ensure its successful repopulation.

In this video profile produced for Teachers' Domain, meet La'ona DeWilde, an environmental biologist who integrates her Athabascan heritage and her Western scientific training to help remote Alaskan villages address environmental issues.

Document use is one of the nine essential skills identified by the Government of Canada to be successful in the workplace. It refers to the skills needed to find, enter, and use letters, numbers, symbols, and images in electronic and paper form.

The Machinist/CNC Technology program is designed to provide students with the skills necessary to gain employment in the manufacturing industry. The first year of the program will focus on skills used in a modern machine shop: machine shop math, blueprint reading, and conventional machine tool theory and lab. An assessment (challenge exam) for prior learning credit for blueprint reading is included.

T-cells rely on Major Histocompatability Complexes (MHC), which are molecules manufactured within cells for the purpose of presenting antigen fragments so that they can be detected by the immune system. MHC has evolved to form two classes for antigen presentation: MHC I presents digested fragments from antigen in cellular cytoplasm, and MHC II presents digested fragments from antigen in the tissue fluid (extracellular). MHC I tends to bind slightly smaller peptides (~9 amino acids) than MHC II (~15 amino acids).

This video from KET traces the energy transformations that occur when coal is burned to produce electricity. Some of the mechanical processes are also described.

This course is an introduction to the use of accounting information by managers for decision making, performance evaluation and control. The course should be useful for those who intend to work as management consultants, for LFM (Leaders for Manufacturing) students, and in general, for those who will become senior managers.

In this video segment adapted from Hope in a Changing Climate, learn how an environmentally devastated ecosystem has been restored, benefiting both the local economy and global efforts to fight climate change.

In this video adapted from NOVA scienceNOW, find out about the discovery of a new building material, the carbon nanotube, whose physical properties could theoretically enable the creation of a 22,000-mile elevator to space.

In this video segment adapted from Haskell Indian Nations University, student filmmakers explain why it is important to them to make a video about climate change.

In this video segment adapted from Navajo Technical College, meet two members of the Navajo Nation, one Elder and one scientist, as they share their observations about how precipitation has changed since they were children.

Learn how snowfall happening later in the year than usual is impacting cultural practices in this video segment about climate change adapted from the College of Menominee Nation.

In this video segment adapted from the College of Menominee Nation, tribal members observe lower water levels in lakes and streams and call for global, collaborative solutions to address climate change.

This video adapted from KTOO explores the impact of oil contamination on the herring population of Prince William Sound, Alaska, in 1999, 10 years after the Exxon Valdez oil spill.

This video segment adapted from NOVA follows the clean-up effort after the 1989 Exxon Valdez oil spill off the coast of Alaska. Also featured is a marsh where an oil spill occurred 20 years earlier; analysis suggests that environmental damage may last for decades.

This introductory video addresses key points as well as pros and cons of oil as an energy source for transportation.

In this video segment adapted from the Yukon River Panel, visit fishing communities along the Yukon River and see how Alaska Native peoples exercise stewardship of salmon to ensure that it remains a central food source and cultural touchstone.

Have we overstepped Mother Earth's boundaries? What are the consequences? In this video segment adapted from Haskell Indian Nations University, hear a Native perspective on our relationship with the natural environment.

(This case study was added to OER Commons as one of a batch of over 700. It has relevant information which may include medical imagery, lab results, and history where relevant. A link to the final diagnosis can be found at the end of the case study for review. The first paragraph of the case study -- typically, but not always the clinical presentation -- is provided below.)

The rapid HIV Multispot test was performed and detests antibody to HIV-1 and HIV-2. The test was read as "preliminary positive" for antibody to HIV-1 according to the manufacturer's guidelines, which state that, "Note: The appearance of any purple color in any of the Test Spots, regardless of intensity, must be considered as presence of that Spot."

This video segment adapted from the NOW-RAMP 2002 Expedition documents a research expedition to Pearl and Hermes Atoll in Hawai`i. Watch as biologists assess the bird and plant populations and then work to eradicate invasive species.
