This video explains how and why Fidel Castro supported the MPLA in Angola from 1975 to 2002. The Battle of Cuito Cuanavale was the largest military confrontation in Africa after World War II. The civil war in Angola was one of the longest and bloodiest conflicts of the twentieth century.

The world is driven by fossil fuels like oil and gas. This has some negative repercussions: Rising energy prices due to decreasing deposits, dependence on unstable oil and gas producing regimes and global warming.
It becomes clear, that a revolution in the way how we produce and use energy is necessary. Central to this energy transition are new technologies, which produce energy from renewable sources such as wind or sun.
With Germany as an example, this clip shows what renewable energies are and how they work as well as what the concept of energy transition means.

The clip is part of the WissensWerte Project of the german non-profit organization /e-politik.de/ e.V.

This patient education program explains the causes and types of anthrax. It also reviews the symptoms, diagnosis, treatment, and prevention of anthrax through vaccination and awareness of bioterrorism. This resource is a MEDLINEplus Interactive Health Tutorial from the National Library of Medicine, designed and developed by the Patient Education Institute.

This is a collection of mini lectures created by anthropologists and those in conversation with anthropology as supplimental material to assist college and university instructors who were made to shift their courses online because of COVID19.For more information, see here.To contribute, please create an OER author account and send your name and OER registered email to AnthropologyTeaching@gmail.com.

The purpose of this video lesson is to expand the student's knowledge about enzymes by introducing the antioxidant enzymes that are intimately involved in the prevention of cellular damage and eventual slowing of the aging process and prevention of several diseases. Students will learn that natural antioxidant enzymes are manufactured in the body and provide an important defense against free radicals. The topic of free radical action is introduced, covering how they are constantly generated in living cells both by ''accidents of chemistry'' and also by specific metabolic processes.

This art history video discussion examines Antoine or Louis Le Nain's "Peasant Family in an Interior", 2nd quarter of the 17th century, oil on canvas (Musee du Louvre, Paris).

Each lecture in this series focuses on a single play by Shakespeare, and employs a range of different approaches to try to understand a central critical question about it. Rather than providing overarching readings or interpretations, the series aims to show the variety of different ways we might understand Shakespeare, the kinds of evidence that might be used to strengthen our critical analysis, and, above all, the enjoyable and unavoidable fact that Shakespeare's plays tend to generate our questions rather than answer them.

Master the Arabic Letters is a video series consisting of eight videos that introduce viewers to the names, shapes, and sounds of the Arabic letters. The videos also explain how to join up the letters in writing and make sure that differences in pronunciation are carefully demonstrated.

This site contains numerous audio, and video files, grouped by topic, of subjects speaking Jordanian colloquial Arabic. There are also a few images and informational links interspersed throughout the site. Each video is available for download and accompanied by an Arabic transcript and an English translation. Videos are based on every day topics like greetings, farewells, shopping, and transportation.

This learning video deals with a question of geometrical probability. A key idea presented is the fact that a linear equation in three dimensions produces a plane. The video focuses on random triangles that are defined by their three respective angles. These angles are chosen randomly subject to a constraint that they must sum to 180 degrees. An example of the types of in-class activities for between segments of the video is: Ask six students for numbers and make those numbers the coordinates x,y of three points. Then have the class try to figure out how to decide if the triangle with those corners is acute or obtuse.

This lesson is based on the results of a performance task in which we realized that students' understanding of area and perimeter was mostly procedural. Therefore the purpose of this re-engagement lesson was to address student misconceptions and deepen student understanding of area and perimeter. The standards addressed in this lesson involve finding perimeter and area of various shapes, finding the perimeter when given a fixed area, and using a formula in a practical context. Challenges for our students included decoding the language in the problem and proving their thinking. (7th Grade Math)

This arithmetic lesson demonstrates more long division problems with remainders.[Arithmetic playlist: Lesson 26 of 38]

You get the general idea of decimal is and what the digits in different places represent (place value). Now you're ready to do something with the decimals. Adding and subtracting is a good place to start. This will allow you to add your family's expenses to figure out if your little brother is laundering money (perhaps literally). Have fun!
