Bear Sleeping Bag Cool bear shaped sleeping bag, designed by Eiko Ishizawa from Amsterdam, will keep you warm and scare your friends when you go camping. Please be warned that, according to the artist, it is not his responsibility if a wild bear attacks you, or some silly hunter hunts you down.

Free Online Course Materials | Physics Whiz Kids At a time when American teens lag far behind other countries in math and science, WHIZ KIDS is a coming-of-age documentary that tells the story of three remarkably different yet equally passionate 17-year-old scientists who vie to compete in the nation's oldest, most prestigious science competition. Win or lose, these ‘whiz kids’ raise questions about class, courage, personal sacrifice, success and failure, and in the process, learn as much about themselves as they do about science. Over the past eight years, countries like China and India vastly increased support for research and development, while U.S. funding remained largely stagnant. As global economies become increasingly competitive, America's future rests on the shoulders of our next generation. The Science Talent Search began in 1942 and is the oldest, most prestigious science competition in America.
Chemistry Freeware On this page I post reviews and links to freeware chemistry programs available for download at other sites around the internet. All of the programs are ones that I have used, or currently use. None-the-less, I take no responsiblity for any problems you might experience as a result of installing any of these applications. Unless otherwise noted, the programs are for Windows systems. ACD/ChemSketch 12 Freeware. ACD continues to release updates to the outstanding Chemsketch freeware. MolView.Org is a web-based molecular viewing and modeling tool. Discovery Studio Visualizer 4. ChemAxon produces a wide range of Java-based chemistry tools, and they offer free academic licenses (you must register with them). The Virtual Laboratory from the ChemCollective is a personal favorite.

Nature Sounds Periodic Table of Elements and Chemistry Instructables - Make, How To, and DIY Science Stage Secret Worlds: The Universe Within - Interactive Java Tutorial Secret Worlds: The Universe Within View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons. Once the tutorial has completely downloaded, a set of the arrows will appear that allow the user to increase or decrease the view magnitude in Manual mode. Click on the Auto button to return to the Automatic mode. Notice how each picture is actually an image of something that is 10 times bigger or smaller than the one preceding or following it.

Bizarre sea slug is half plant, half animal It looks like any other sea slug, aside from its bright green hue. But the Elysia chlorotica is far from ordinary: it is both a plant and an animal, according to biologists who have been studying the species for two decades. Not only does E. chlorotica turn sunlight into energy — something only plants can do — it also appears to have swiped this ability from the algae it consumes. Native to the salt marshes of New England and Canada, these sea slugs use contraband chlorophyll-producing genes and cell parts called chloroplasts from algae to carry out photosynthesis, says Sidney Pierce, a biologist at the University of South Florida in Tampa. That genetic material has since been passed down to the next generation, eliminating the need to consume algae for energy. However, the baby slugs can’t carry out photosynthesis until they’ve stolen their own chloroplasts, which they aren’t yet able to produce on their own, from their first and only meal of algae.
Chemistry Review Activities I re-organized the course during the 2014 - 2015 school year. Some review activities were moved to new units. This has resulted in a change to some of the file names, so direct links to the individual activities may need to be changed. These are not graded assignments. Unit 0 - The Methods of Chemistry Unit 1 - Atomic Structure Unit 2 - Periodic Behavior and Ionic Bonding Element Classes Review - Unit 2 Benchmark #1 (Matching Activity) Element Classes Review 2 - Unit 2 Benchmark #1 (Multiple Choice) Element Classes Review - Unit 2 Benchmark #1. Unit 3 - Covalent Bonding and Molecular Structure Lewis Structures - Unit 3 Benchmark #1 Lewis Structures #2 - (HTML5/ Mobile Compliant)Binary Covalent Nomenclature - Writing formulas using names, and writing names using formulas. Unit 4 - Conservation of Matter First Semester Review Semester 1 Millionaire Game. Unit 5 - Reaction Energy and Kinetics Unit 6 - Water NOTE: This unit was previosly titled "Solids, Liquids and Solutions".
How to Trick Your Brain for Happiness This month, we feature videos of a Greater Good presentation by Rick Hanson, the best-selling author and trailblazing psychologist. In this excerpt from his talk, Dr. Hanson explains how we can take advantage of the brain’s natural “plasticity”—it’s ability to change shape over time. gobyg There’s this great line by Ani Tenzin Palmo, an English woman who spent 12 years in a cave in Tibet: “We do not know what a thought is, yet we’re thinking them all the time.” It’s true. In recent years, though, we have started to better understand the neural bases of states like happiness, gratitude, resilience, love, compassion, and so forth. Ultimately, what this can mean is that with proper practice, we can increasingly trick our neural machinery to cultivate positive states of mind. But in order to understand how, you need to understand three important facts about the brain. Fact one: As the brain changes, the mind changes, for better or worse. Fact two: As the mind changes, the brain changes. 1. 2. 3.

Current Review Gravity Space movies, such as "Gravity," are almost always grandiose in their storytelling aspirations. The enormity of space, the raw power of a space shuttle, the existential quandary of whether we are alone in a vast universe, and (as is the case in "Gravity") an inevitable crisis that must be resolved to steer astronauts to safety. Current Recommendation 'How To Survive A Plague' The history of science movies and the Oscars is not a very long one. Recent Recommendation 'Last Call At The Oasis' Watching the havoc caused by Hurricane Sandy and other recent water-related natural disasters, it's hard to imagine that global water shortages represent an environmental crisis on par with climate change.
