Interactive Learning Sites for Education - Home Word of the day "… so we repaired to a publick-house, took a friendly glass, and thus parted." — Peter Drake, Amiable Renegade: The Memoirs of Captain Peter Drake, 1671–1753, 1960 "… Warren repaired to the dining alcove off the kitchen … and ate dinner with Nina and the children, discussing their schoolwork and events of the day." — Kevin Starr, Embattled Dreams, 2002 We are all familiar with the verb repair used as a synonym of fix. But today's word, while it is a homograph and a homophone of the more familiar repair, is a slightly older and unrelated verb. Repair, the synonym of fix, comes via Anglo-French from the Latin reparare, a combination of the re- prefix and parare ("prepare"). Test Your Memory: What former Word of the Day refers to the study of the origin and forms of proper names?

TeacherTube - Teach the World Find and compare free online courses from Coursera, Udacity, edX and more Vocabulary Practice With Rap Your Words Vocabulary Practice With Rap Your Words Posted on Thu, Sep 15, 2011 I love being able to let popular celebrities inspire my students with a positive educational message, especially the most unlikely ones. Eminem did my work for me when he was interviewed by 60 Minutes; he talked about how he can rhyme unlikely words together and therefore has an almost obsessive need to know as many words as possible. That one snippet of his interview alone is a great inspiration as to why students should care about learning new vocabulary! I also use his interview to prime students right before I assign them to write their own vocabulary raps (or song lyrics if students would rather not rap but sing). My students team up in pairs and have to use at least 15 of the 20 vocabulary words of their current unit. The vocabulary words have to be used in context and must make sense; furthermore, the lyrics need to be clean and not cruel.
top20biology.com Physics with Calculus/Mechanics/Scalar and Vector Quantities Introduction The study of physics is intimately tied in with the study of mathematics. Sometimes, the direction of a number or quantity is as important as the number itself. Mathematicians in the 19th century developed a convenient way of describing and interacting with quantities with and without direction by dividing them into two types: scalar quantities and vector quantities. Scalar quantities have a magnitude but no direction. Vector quantities have both a magnitude and a direction. Scalar Quantities Scalar quantities are numbers that have a magnitude but no direction. . Vector Quantities Vectors are a geometric way of representing quantities that have direction as well as magnitude. When vectors are written, they are represented by a single letter in bold type or with an arrow above the letter, such as or . Unit Vectors An illustration of common choice of unit vectors in a Cartesian coordinate system , and ). Unit vectors are generally chosen to be orthogonal. and
