Biology History The objects of our research will be the different forms and manifestations of life, the conditions and laws under which these phenomena occur, and the causes through which they have been effected. The science that concerns itself with these objects we will indicate by the name biology [Biologie] or the doctrine of life [Lebenslehre].

Students play the role of epidemiologists looking for clues to solve the case of a mystery disease, watch simulations of herd immunity & the impact of vaccination programs, & assign limited funds to three proposals submitted to address a major infectious disease. (NIH) The target audience is grades 9-12.

Solar-powered sea slug harnesses stolen plant genes - life - 24 November 2008 Video: Watch a sea slug eat algae to nab some of its chloroplasts, and the genes that keep them functioning It's the ultimate form of solar power: eat a plant, become photosynthetic. Now researchers have found how one animal does just that. Elysia chlorotica is a lurid green sea slug, with a gelatinous leaf-shaped body, that lives along the Atlantic seaboard of the US. What sets it apart from most other sea slugs is its ability to run on solar power. Mary Rumpho of the University of Maine, is an expert on E. chlorotica and has now discovered how the sea slug gets this ability: it photosynthesises with genes "stolen" from the algae it eats. Physics with Calculus/Mechanics/Scalar and Vector Quantities Introduction[edit] 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.

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).

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").

30 Ways to Define Leadership Credit: Rawpixel/Shutterstock Webster's Dictionary defines leadership as "the power or ability to lead other people," but for most people, there's a lot more to it than that. Ask anyone what it means to be a leader, and you'll likely hear something unique every time. That's because everyone has his or her own idea of what leadership is, but not every boss leads a team the same way. Some people think leadership means guiding others to complete a particular task, while others believe it means motivating the members of your team to be their best selves.

12 Dozen Places To Educate Yourself Online For Free All education is self-education. Period. It doesn’t matter if you’re sitting in a college classroom or a coffee shop. We don’t learn anything we don’t want to learn. Falser Words Were Never Spoken IN a coffee shop not long ago, I saw a mug with an inscription from Henry David Thoreau: “Go confidently in the direction of your dreams! Live the life you’ve imagined.” At least it said the words were Thoreau’s. But the attribution seemed a bit suspect. Thoreau, after all, was not known for his liberal use of exclamation points. When I got home, I looked up the passage (it’s from “Walden”): “I learned this, at least, by my experiment: that if one advances confidently in the direction of his dreams, and endeavors to live the life which he has imagined, he will meet with a success unexpected in common hours.”
