The Biology Corner This worksheet provides steps for identifying structures of the grasshopper, with a focus on the external anatomy and mouthparts. The lesson can be part of a larger unit on insects … In animals, form and function are closely related.
What would disprove evolution? If evolution is a scientific theory worth its salt, then there must be some conceivable observations that could show it to be wrong. I just wanted to put down, for the record, what some of those observations might be. First, let’s reprise what I see as the major components of the theory of evolution. Evolution occurs, that is, there is gene frequency change in populations over generations.Significant evolution takes time—that is, it usually (though not always) requires hundreds to thousands of generations to occur.
Scientists discover brain chemical that eases the pain of financial loss By Daily Mail Reporters Updated: 02:12 GMT, 22 February 2012 Scientists have found that a chemical in the brain allows people to brush off the pain of financial losses. The breakthrough discovery could pave the way to the development of drugs to treat problem gamblers. The chemical is active in the region of the brain involved in sensory and reward systems and its existence sheds light on what may have been going on in the brains of Wall Street and City of London traders as the 2008 financial crisis took hold. Addiction: The chemical could pave the way to the development of drugs to treat problem gamblers

Zygote Body - Interactive Human Body Browser for your Whiteboard Biologists who wanted a human body browser in the same style as Google Earth, Google Sky, Google Moon etc got very excited a few years ago when Google brought out its Body Browser. They then got sad when Google retired it. Well it looks like it’s back (sort of) under new management and is now called Zygote Body.

The brain is actually wired like a chess board and a new scanner reveals how in stunning detail By Ted Thornhill Published: 10:04 GMT, 30 March 2012 | Updated: 15:31 GMT, 30 March 2012 For a long time it was thought that the brain was a mass of tangled wires, but researchers recently found that its fibers are actually set up like a chess board, crossing at right-angles. What’s more, this grid structure has now been revealed in amazing detail as part of a brain imaging study by a new state-of-the-art magnetic resonance imaging (MRI) scanner. Van Wedeen, of Massachusetts General Hospital (MGH), who led study, said: ‘Far from being just a tangle of wires, the brain's connections turn out to be more like ribbon cables - folding 2D sheets of parallel neuronal fibers that cross paths at right angles, like the warp and weft of a fabric.
Ten Recent Advances in Evolution By Carl Zimmer Posted 10.26.09 NOVA To celebrate the 150th anniversary of the Origin of Species, here's a list—by no means exhaustive—of some of the biggest advances in evolutionary biology over the past decade. These advances include not just a better understanding of how this or that group of species first evolved, but insights into the evolutionary process itself. In some cases those insights would have given Darwin himself a pleasant jolt of surprise. Ten significant leaps forward in evolution research in the past decade, as chosen and described by noted science writer Carl Zimmer Enlarge Photo credit: (Earth) © NASA; (text) © WGBH Educational Foundation Earth - The making of me and you This story is part of BBC Earth's "Best of 2016" list, our greatest hits of the year.

How plants work - Science (4) - ABC Splash - Overview Plants are the only living things that can make their own food. They do this during the day while it's light, using a process called photosynthesis, which uses carbon dioxide and produces oxygen. During the day and night plants take in oxygen and release carbon dioxide through respiration. Discover just how important plants are to life on Earth. The Simulation News and Announcements The Human Brain Project to present at Swisstech Open Days Representatives of the Human Brain Project (HBP) will be presenting at the grand opening of the Swiss Tech Convention Center, at EPFL in Lausanne on the weekend of 5-6 April 2014.

educreations teacherswithapps Educreations Interactive Whiteboard, by Educreations, Inc, is an incredible, yes that’s right, INCREDIBLE app. This newly released app comes with the huge bonus of being FREE! We think this app has the edge needed to push education in the right direction and to begin modernizing teaching as we know it. Educreations is not the first app using the whiteboard concept, but it is the first one geared specifically for the classroom. Educreations wants to give teachers the opportunity to create what Sal Khan has been doing for years (read our review of Khan Academy). Log In Video The Times’s Quentin Hardy talks with Mary Roach about her new book, “Gulp: Adventures on the Alimentary Canal.” Overview | In this lesson, students research the digestive system in depth, and then create a detailed walk-through model to illustrate each compartment.Materials | Computers with Internet access, projection equipment, an assortment of art supplies (butcher paper, fabric, yarn, cardboard, colored paper, tissue paper, paints, markers, glue, staplers, tape, scissors, etc.) Warm-up | When students arrive, project “Gulp! The Quiz” at the front of the room.
