Houdini Honey Badgers Can Escape From Anywhere So half the Internet has seen the video about what total badasses honey badgers are (reminder at bottom for those who want a second look). But they don't just have attitude. As this clip from a BBC documentary reveals, they're also really smart. We know a lot of people who wouldn't be able to work out how to get out of an enclosure like this. It is amazing to think that barely 50 years ago Jane Goodall was mocked for producing evidence that chimpanzees use tools. Myths and misconceptions about evolution - Alex Gendler "A human being, looking at the natural world, sees a thousand times purpose. A rabbit's legs, built and articulated for running; a fox's jaws, built and articulated for tearing. But what you see is not exactly what is there..." starts a blog by Eliezer Yudkowsky. Biological evolution is descent with modification. This definition encompasses small-scale evolution (changes in gene frequency in a population from one generation to the next) and large-scale evolution (the descent of different species from a common ancestor over many generations). Evolution helps us to understand the history of life.

National Geographic's Great Nature Project All wildlife Take and upload a photo of a plant, animal, or any other living thing you come across to help us compile the world’s largest collection of nature photos. Sign in to join mission Nature adapts to Chernobyl Chernobyl: 28 years after disaster On April 26, Ukraine marks the 28th anniversary of the Chernobyl disaster, the worst nuclear accident in history. Take a look at haunting scenes from inside the exclusion zone. 25, 2014 Novoshepelychi, Ukraine: The clicking sound from Timothy Mousseau's radiation detector slowly increased as he walked through the forest here, a few miles west of the Chernobyl nuclear power plant.

How do your kidneys work? - Emma Bryce Kidneys play a vital role in your body. Why are kidneys so important? Visit the National Kidney Foundation and find out more details about hypertension, diabetes and other ways they can become damaged. Click this link and find out how to keep those kidneys healthy. Despite what they may look like from the outside, the kidneys are more than just a pair of little beans. Arctic Unit Week 1 This was meant to be our first January unit, but lack of routine and school was getting to us so we went ahead and started a week early. First we looked for the Arctic Circle on our globe and talked about the different countries that make up the Arctic land. I pointed out the Arctic Ocean. (We haven’t really talked about the names of the oceans yet. Does anyone have a good song for that?)

Darwin/Lamark court case By Don Mills This six to seven 40 minute period activity allows students to role play while learning theories of evolution. To start this activity have your students write their names on scrap pieces of paper. Read the list of roles to the class.

The Habitable Planet Unit 4 - Ecosystems // Online Textbook Ecosystems maintain themselves by cycling energy and nutrients obtained from external sources. At the first trophic level, primary producers (plants, algae, and some bacteria) use solar energy to produce organic plant material through photosynthesis. Herbivores—animals that feed solely on plants—make up the second trophic level. 7 Free iPad Apps for Science Lessons Cross-posted from my other blog I'm preparing to do a virtual presentation for a small district next month. My hosts asked for a list of some science apps that their middle school and high school students can use. This is part of the list that has free apps.

guppy The purpose of this activity is to analyze how guppy populations change over time. The simulation activity allows you to start with a pool of guppies and your choice of predators, you will be able to watch what happens to your guppy population and how the introduction of predators can affect the guppy's appearance. The simulation will help you understand what pressures drive guppy evolution. *Activity adapted from PBS - Open the Guppy Sex Simulator!!! --

The Story of Cholera Cholera is caused by Vibrio cholerae, a Gram negative, curved rod-shaped bacterium. For more information about its taxonomy and structure, go to the National Institutes of Health or the World Health Organization. Cholera caused discord when an outbreak in Haiti after the 2010 earthquake killed more than 8,000 citizens. The country had not dealt with a cholera epidemic in a century, according to a Foreign Affairs article about the situation, "Peace and Pestilence," which also described the outrage that spread when investigators discovered the origins of the pathogen in Haiti.
