How big does a mirror have to be for you to see yourself in it? Exploratorium staff physicist Thomas Humphrey describes an activity you can use in your classroom to investigate simple optics. TI staff educator Modesto Tamez explains how to make a simple straw oboe that will bring down the house (and teach good physics!) TI staff educators Lori Lambertson and Tory Brady explore the math behind the morning paper.
We speak with glaciologists Slawek Tulaczyk and Jake Walter, who study ice-sheet dynamics. Join us as we talk to scientists working with IceCube, a neutrino telescope buried in the ice under the South Pole. The air is so dry here at McMurdo that anything that gets charged, stays charged. Moist air quickly discharges objects because the water in the air picks up charge from an object and quickly flies away, taking charges with it. This does not happen here. We are constantly getting shocks from our clothing, our bedding and when we exit vehicles. Halloween Special Edition! In this zany competition teachers have ten minutes to create a science activity from a special Halloween secret ingredient... bats! An interview with science historian Richard Carrier.
It's not enough to know that a nutcracker works; a scientist needs to know why. Historian Richard Carrier recounts how, in ancient Greece, pondering the nutcracker led to the physics of levers. He describes how Aristotle and others shaped the beginnings of Western scientific thought: the notion that knowledge of the natural world relies on being able to question, test, reproduce and improve the accuracy of what's believed to be true. He explains why he sees science as a practice rooted in values, how it protects us from our own erroneous tendencies, and why questioning authority helps foster scientific thinking.
All wound up with nothing to do? Swing by the Exploratorium on September 6th, beginning at 10am, for the 2008 California State Yo-Yo Championships.
