This brief video segment produced for Teachers' Domain features time-lapse video of a sunrise and a sunset.
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.
The lesson begins by introducing Olympics as the unit theme. The purpose of this lesson is to introduce students to the techniques of engineering problem solving. Specific techniques covered in the lesson include brainstorming and the engineering design process. The importance of thinking out of the box is also stressed to show that while some tasks seem impossible, they can be done. This introduction includes a discussion of the engineering required to build grand, often complex, Olympic event centers.
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.
Against the backdrop of the devastating 1930's Dust Bowl, this video segment adapted from Interactive NOVA profiles an organic farmer and the techniques he uses to conserve topsoil.
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.
Video lesson provides an overview of animal and plant cells while covering cell walls, vacuoles, chloroplasts, peroxisomes, lysosomes, mitochondria, etc. [8:41]
Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.
How do we use radiation in our lives, and is it safe for humans? How do we use radiation in our lives, and is it safe for humans? This unit begins with a news article about the unconventional use of microwave ovens to store electronics. Students are motivated to test the behavior of a Bluetooth speaker playing music from a device inside the oven when it is not running. They also test what happens when it runs and heats up food. This phenomenon sets the stage for exploring wave behavior, the interactions of matter with electromagnetic radiation, and how we can use these interactions in different technologies to digitize, store and transfer information. Throughout the unit, students use simulations to model field interactions and energy transfer through electromagnetic radiation. They conduct investigations using the microwave oven to explore how different materials interact with microwave radiation, and how the structure of this device affects energy transfer. Students explain how the frequency and amplitude of electromagnetic radiation affects its interactions with matter and evaluate the wave and photon models of electromagnetic radiation. Students obtain and communicate information about the uses of electromagnetic radiation, its safety, and methods of protection. They apply these ideas in a culminating task to evaluate whether 5G technology is safe.

A wonderful PBS biography of a great man. This contains many personal touches, yet does a fine job of describing Bohr's scientific work. But it's best at Bohr the man. Nice quotes, one in the middle, one at the end.
The difference between an architect and an engineer is sometimes confusing because their roles in building design can be similar. Students experience a bit of both professions by following a set of requirements and meeting given constraints as they create a model parking garage. They experience the engineering design process first-hand as they design, build and test their models. They draw a blueprint for their design, select the construction materials and budget their expenditures. They also test their structures for strength and find their maximum loads.
