  • Can animals be deceptive? - Eldridge Adams
    December 18, 2018

    Sign up for our newsletter and never miss an animation: http://bit.ly/TEDEdNewsletter View full lesson: https://ed.ted.com/lessons/can-animals-be-deceptive-eldridge-adams A male firefly emits a series of enticing flashes. He hopes a female will respond and mate with him. A female from a different species mimics his patterns: by tricking the male, she lures him in -- and turns him into a meal. Where else do we see this kind of trickery in the animal kingdom? Eldridge Adams details the surprising complexity of how animals manipulate predators, prey and their rivals.

  • The HOT Chocolate Effect
    December 17, 2018

    This experiment is called the Hot Chocolate Effect. You can do it yourself quite easily. Pour Cocoa mix in the cup and pour HOT water into the cup and then tap the rim of your mug several times with your spoon and listen to the pitch. Did it change while you were tapping? Probably Not! Now this is where SCIENCE becomes FUN! Give it a couple of stirs and start tapping again. What do you hear? You should notice that the pitch frequency of your tapping gets higher and higher. Give it another stir and tap again. The pitch will go down and then rise again! What’s the science behind it? DRUM ROLL.....answer is BUBBLES. Adding powdered hot cocoa mix doesn’t just add a sweet chocolate flavor to your water, it adds tiny bubbles of air as well. As you stir in the chocolate you also mix the air bubbles into the liquid. All of those bubbles slow down the speed of sound in the hot chocolate. This lowers the frequency or the pitch of the sound waves that travel through the mug when tapped. As the water spins around in the mug, the bubbles rise to the top and pop. With fewer bubbles in the hot chocolate, the speed of sound increases and the frequency does too so you hear a higher pitch. Now stir it again and it dissolves more bubbles and it starts all over again! The hot chocolate effect, also known as the allassonic effect, is a phenomenon of wave mechanics first documented in 1982 by Frank Crawford, where the pitch heard from tapping a cup of hot liquid rises after the addition of a soluble powder(Coca mix, instant coffee). Hope you enjoyed this experiment. Please Like and SHARE. And thanks for watching

  • Little Theater and American Avant Garde: Crash Course Theater #40
    December 15, 2018

    In the early 20th century United States, big melodramatic productions were on Broadway, and everywhere across the country. Which inevitably led to an Avant-Garde backlash. An interesting part of the backlash was Little Theater, a movement that embraced smaller, more emotional, and less profitable forms of drama. One of Little Theater's most notable practitioners, Eugene O'Neill changed the theatrical landscape with groundbreaking plays like The Iceman Cometh and Long Day's Journey into Night.

The dough is kneaded, rolled out, and cut evenly into thin noodles, similar in thickness to spaghetti. Gaining popularity in the 1600s during Japan's Edo period, the eating of soba noodles grew due to their health benefits and ability to prevent beriberi, a disease caused by thiamine (vitamin B-1) deficiency. Today, you can find soba noodles in restaurants around the world, served chilled with dipping sauce (zaru soba) or in a warm broth (bukkake soba).

  • Neural Networks: Crash Course Statistics #41
    December 12, 2018

    Today we're going to talk big picture about what Neural Networks are and how they work. Neural Networks, which are computer models that act like neurons in the human brain, are really popular right now - they're being used in everything from self-driving cars and Snapchat filters to even creating original art! As data gets bigger and bigger neural networks will likely play an increasingly important role in helping us make sense of all that data. Special thanks to Max Deutsch giving us permission to use his Neural Network-written Harry Potter chapter in this episode!

  • Chitty Chitty Bang Bang Jr Car
    December 10, 2018

    The making of Chitty Chitty Bang Bang Jr Car This is NOT a Science experiment. This is what I have been working on the last couple months and why I haven't posted a science experiment. I volunteer at the local Middle school Drama department and design and make all their props and sets. You can go to my pinterest page at https://www.pinterest.com/kenzschach/ . Email me if you have any questions if you want to make a car. We are on very tight budget and was able to make the car for $300, which is pretty good as the steeling wheel & picnic basket cost $40. All the outside walls of the car are made out of card board and everything is manual. I mean actors pull a wire cord to bring up the wheels when it floats on water and couple of wires cords for the wings so it can fly. I hope you enjoyed this as much as I did making it. I will be back to Science experiments next weekend. thanks

  • Futurism and Constructivism: Crash Course Theater #39
    December 7, 2018

    It's time to go Back...to the Future. By which I mean, we're going back into the past to talk about Futurism. Which seems like it would be cool, but it was started by this terrible guy Martinetti, who also wrote the Italian Fascist manifesto. He was just the worst, but, at least he was the worst in a way that makes a pretty compelling video. We'll also check in with the Russian theater, and learn about generally nicer Futurist Vsevolod Meyerhold, who also was vey influential in constructivism.

  • Engineering Ethics: Crash Course Engineering #27
    December 6, 2018

    We’ve talked about many important concepts for engineers, but today we’re going to discuss a hugely important one that you might not even realize is an engineering concept: ethics. We’ll talk about what a Code of Ethics is. We’ll explore engineering ethics and the ethical theories of utilitarianism, rights ethics, and duty ethics. We’ll also take a look at a few different real life examples of ethical problems in engineering.

  • Expressionist Theater: Crash Course Theater #38
    November 30, 2018

    Join us here, in the darkness. Our theater journey takes us into the heart of expressionism today, as playwrights in the late 19th and early 20th centuries explored the limits of human beings' tolerance for a mechanized, industrial world. Spoiler alert: those playwrights didn't think humans fared very well in the industrialized world. They EXPRESSED that concern about modernity through some pretty dark plays, with pretty dark sets, and pretty dark content. Crash Course is on Patreon!

  • Why should you read Kurt Vonnegut? - Mia Nacamulli
    November 29, 2018

    Download a free audiobook version of "Slaughterhouse Five" and support TED-Ed's nonprofit mission: https://adbl.co/2DPI5Ys Check out our full book recommendation: https://shop.ed.ted.com/products/slaughterhouse-five Kurt Vonnegut found the tidy, satisfying arcs of many stories at odds with reality, and he set out to explore the ambiguity between good and bad fortune in his own novels. He tried to make sense of human behavior by studying the shapes of stories — ditching straightforward chronologies and clear-cut fortunes. Mia Nacamulli dives into the sometimes dark, yet hopeful works of Vonnegut. Lesson by Mia Nacamulli, directed by TED-Ed. Thank you so much to our patrons for your support!

    Our red panda cubs had SNOW much fun today experiencing their first snowfall. Red pandas have a soft, dense woolly undercoat covered by a second layer of long coarse hair. Their long, bushy tails help them maintain balance and they wrap it around themselves like a blanket when they sleep. Dense fur completely covers their feet to protect them from the cold.
