This video segment adapted from NASA's Goddard Space Flight Center shows how integral satellites are to everyday life and describes the different types, including orbital and geostationary.

In this video segment adapted from NOVA, a geologist digs a trench along the San Andreas Fault to reveal three thousand years of earthquake history. Information from the layers of sediment may help geologists to predict earthquakes.

This article provides background information that will help teachers present the science associated with the study of climate, past, present and future. The magazine Beyond Weather and the Water Cycle is structured around the recognized principles of climate literacy. The author explains the science concepts included in the principle related to climate study and research and also identifies additional sources of information.

This list of carefully selected books for grades K-5 highlights nonfiction about climate proxies, those preserved physical characteristics, such as fossils, that scientists use to reconstruct past climates. Also highlighted are a few books that provide information about two past climatic events -- the last ice age and the Dust Bowl. In each issue of the free, online magazine Beyond Weather and the Water Cycle, the virtual bookshelf recommends books that accurately portray the theme drawn from the principles of climate sciences.

In this video produced for Teachers' Domain, Chi-An Wang, a mechanical engineering graduate from the Massachusetts Institute of Technology, describes her process when working with New Balance to design a new triathlon shoe.

When machines or computers are used to automate a task, does that mean that human workers will lose their jobs? As with most questions in economics, it depends. See how computers and toilet paper illustrate two different effects of technology on jobs. Overall, EconGuy shows that even when workers in one industry lose out, the economy as a whole benefits from automation and technology.

Have you encountered mobile payment systems like mobile credit card readers? Pretty cool—and this kind of innovation can be good for the economy. From micro to macro, in this episode of The Economic Lowdown podcast series, we'll take a look at economic growth—how innovation and technological progress can make things happen for the economy over time by organizing the factors of production to be, well, more productive.

This course is a survey of world economic history, and it introduces economics students to the subject matter and methodology of economic history. It is designed to expand the range of empirical settings in students’ research by drawing upon historical material and long-run data. Topics are chosen to show a wide variety of historical experience and illuminate the process of industrialization. The emphasis will be on questions related to labor markets and economic growth.

Looking for engaging content for your economics courses? The Institute for Humane Studies has curated this collection of educational resources to help economics professors enrich their curriculum. Find videos, interactive games, reading lists, and more on everything from opportunity costs to trade policy. This collection is updated frequently with new content, so watch this space!

In this video from Science City, meet Eduardo Torres-Jara, a postdoctoral associate in electrical engineering and computer science at the MIT Artificial Intelligence Lab. He describes his work on innovative robots that use tactile feedback to locate and grasp objects.

Educational Technology is a broader term first try to understand what technology is?Technology is something that make our work easier like a tractor makes the farmer's work easier so it is farming technology washing machine makes the household work easier so it is a house hold technology. Similarly things that makes education easier is educational technology like ppt;'s computers smart phones and even a chalk stick is a part of technology as it too makes the work easier for a teacher.

The Educator & Staff Professional Learning Plan is one component of the K-12 Voices for Open OER - DEIA Action Planning Guide.  This plan, and the entire guide, is intended as a strategic planning tool for district leaders wishing to promote the already pedagogically and financially compelling practice of creating or adapting open educational resources (OER) to help achieve district goals in serving all students through diversity, equity, inclusion, or accessibility (DEIA) lens.  The guide provides step-by-step planning tools, including examples, templates, and resources to help district leaders articulate and establish action plans for what we refer to as "OER-DEIA."  The entire guide is an open educational resource itself, free and openly licensed for reuse, remixing, and resharing.

Interactive Lecture Demonstration to illustrate that impulses are larger in elastic collisions than in inelastic collisions if other factors are the same.

This collection uses primary sources to explore the introduction of electric power to the United States. Digital Public Library of America Primary Source Sets are designed to help students develop their critical thinking skills and draw diverse material from libraries, archives, and museums across the United States. Each set includes an overview, ten to fifteen primary sources, links to related resources, and a teaching guide. These sets were created and reviewed by the teachers on the DPLA's Education Advisory Committee.

In this activity, the students will complete the grand challenge and design an electromagnet to separate steel from aluminum for the recycler. In order to do this, students compare the induced magnetic field of an electric current with the magnetic field of a permanent magnet and must make the former look like the latter. They discover that looping the current produces the desired effect and find ways to further strengthen the magnetic field.

In this animation produced by WGBH and Digizyme, Inc., see how molecules of DNA are separated using gel electrophoresis, and how this process enables scientists to compare the molecular variations of two or more DNA samples.

In this electrochemistry activity, learners will explore two examples of electroplating. In Part 1, zinc from a galvanized nail (an iron nail which has been coated with zinc by dipping it in molten zinc) will be plated onto a copper penny. In Part 2, copper from a penny will be plated onto a nickel.

In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water. The plastic will attract the surface of the water into a visible bump.

Use a series of interactive models and games to explore electrostatics. Learn about the effects positive and negative charges have on one another, and investigate these effects further through games. Learn about Coulomb's law and the concept that both the distance between the charges and the difference in the charges affect the strength of the force. Explore polarization at an atomic level, and learn how a material that does not hold any net charge can be attracted to a charged object. Students will be able to:

Students will learn about magnification and how a magnifying lens works. They will examine a variety of different objects, first without a magnifier and then with a magnifier, and compare what they observe. They will practice observing details of these objects with magnifying lens. The purpose of this activity is for students to learn about observation skills and how tools can help people make observations, what "magnification" means, and to learn that scientists use tools, such as magnifying lenses, to examine objects. Students will be able to identify a magnifying glass and its purposes. They will be able to describe how the same object looks different when using the unaided eye versus a magnifying lens.
