Paul Andersen explains how an overall chemical reaction is made up of several elementary steps. The stoichiometry of this equation can be predicted but the rate law must be measured. If the elementary steps of the reaction are determined the rate law of this individual step may be predicted.
Students are introduced to the futuristic concept of the moon as a place people can inhabit. They brainstorm what people would need to live on the moon and then design a fantastic Moon colony and decide how to power it. Students use the engineering design process, which includes researching various types of energy sources and evaluating which would be best for their moon colonies.
This online video briefly shows glacial loss in North and South America between 2003 and 2010. The resource, "NASA Goodbye Glaciers" included in "Lesson 3 Black Ice" is a part of "Unit 03 Challenges to Safe Operating Space" included in Energy & Sustainability ES - Course 2.
Danielle Roosa, granddaughter of Apollo 14 astronaut Stuart Roosa, demonstrates NASA and Microsoft's free Kinect interactive Xbox video game, 'Mars Rover Landing.' The new game lets players try their skill at landing the Curiosity rover on Mars. The game is available free of charge in the Xbox Live Marketplace and Kinect Central.
The video resource "Naked Eye Observations: Crash Course Astronomy #2" is included in the "Astronomy" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.

Through two lessons and four activities, students learn about nanotechnology, its extreme smallness, and its vast and growing applications in our world. Embedded within the unit is a broader introduction to the field of material science and engineering and its vital role in nanotechnology advancement. Engaging mini-lab activities on ferrofluids, quantum dots and gold nanoparticles introduce students to specific fields within nanoscience and help them understand key concepts as the basis for thinking about engineering and everyday applications that use next-generation technology nanotechnology.
Student teams learn how water filtration systems that use nanoparticles and nanotechnology can remove organic compounds from water. First they learn about the role nanoparticles play in water filtration. Then they are introduced to the basics of nanoparticles and nanotechnology, focusing on the impacts and benefits this innovative technology has on our daily lives. Using methylene blue and methyl orange solutions, students test for the efficiency of photocatalytic nanoparticles to sanitize water. They expose a solution sample of water and methyl orange (the microbe indicator) with their newly-made water sanitation filters under UV light (sunlight) to activate the photocatalytic properties of three specific nanoparticles. They visually compare them with control samples to determine the best photocatalytic nanoparticle to sanitize water.
Paul Andersen explains how the Earth's climate will natural change due to interactions between the Sun and Earth, volcanism, and plate tectonics. Species may go extinct leading to adaptive radiation or may move to a suitable climate. Primary and secondary succession are also discussed.
The purpose of this text is to promote understanding of the Geographic Information Science and Technology enterprise (GIS&T, also known as “geospatial”).
For thousands of years, navigators have looked to the sky for direction. Today, celestial navigation has simply switched from using natural objects to human-created satellites. A constellation of satellites, called the Global Positioning System, and hand-held receivers allow for very accurate navigation. In this lesson, students investigate the fundamental concepts of GPS technology trilateration and using the speed of light to calculate distances.
