A stack of blocks seems to defy gravity in this activity by Exploratorium staff educator Don Rathjen.
Staff Neuroscientist Richard Brown demonstrates that the Giant Mirror reflects infrared radiation as well as visible light. In conjunction with this summer's special exhibition Reflections, Exploratorium Senior Scientist Paul Doherty joins us for a hands-on Webcast. What effect does looking through two mirrors have on an image? Or three mirrors? What is dark energy? Cosmologist Rocky Kolb explains how the South Pole Telescope will help us understand the properties and nature of this mysterious force. Join Senior Scientist Paul Doherty as he measures the power used by two lightbulbs--one incandescent and one fluorescent--that make the same amount of light. A century after publication of Einstein's famous papers on light and relativity, this most celebrated of Nobel Laureates will be the subject of a talk by award-winning science writer K.C. Cole. She'll discuss the ways in which Einstein continues to influence physics today, from detecting gravity waves to understanding string theory. In this zany competition teachers will have ten minutes to create a science activity from a special St. Patrick's Day secret ingredient-things that are green! The concept of space-time--perhaps Einstein's most fundamental contribution to our understanding of the universe--will be explored using special red lasers. Watch as the best teachers on the planet battle it out for the title of Iron Science Teacher. In this zany competition teachers will have ten minutes to create a science activity. This week’s “secret” ingredient: Clothespins! How does your eye work? You see the world because light gets into your eyes. Your eye uses that light to make an image of the world inside your eye—just as a camera uses light to make a photograph. At the Exploratorium, we dissect cow eyes to show people how an eye functions, and look at the parts that make up an eye.
This video shows and explains a dissection with one of our staff Explainers.
