The Science of 3-D Glasses

3D images of the surface of Mars are being sent to earth as a result of NASA’s recent unmanned mission to the red planet. These images have contributed to a recent fad…3D glasses. An article in Thursday’s issue of USA Today, “Geeky 3-D glasses are looking good” , describes this recent obsession.

  • You can find information about 3D vision from the Optometrists’s Network at
  • At the U.S. Geological Survey’s TerraWeb for Kids you will find:
    1. instructions for making your own 3D glasses
    2. 3D satellite images of Earth taken from outer space
    3. create your own 3D landscape
  • Many sites on the web will send you a free pair of 3D glasses (the cardboard variety). You can find the necessary information in the USA Today article, at either of the Web sites listed above, or try a search on Google for “3-D glasses.”

100th Anniversary of Flight

100 years ago today, Wilbur and Orville Wright, better known as the Wright Brothers, flew 120 feet over the beaches of Kitty Hawk, North Carolina in a powered aircraft to become pioneers in aviation.

The following sites have some ideas for activities and experiments related to aviation and aeronautics:

  • Science Fun with Airplanes
  • Celebrating 100 years of flight at the Scholastic Teachers Web site
  • Aeronautical Classroom Activities from NASA
  • Airplane Lesson Plans from Lesson Planet
  • Bubble-ology

    Bubbles and balloons can be used to teach the following concepts: Bernoulli’s principle, color, images, light and surface tension.

  • Ms. Cheek 4th grade teacher from Kennesaw, Georgia, has a list of bubble-related web pages on her classroom website.
  • The Nueva School has a list of links related to bubbles and ballons.
  • The Exploratorium provides information about bubbles, recipes for bubble mixtures, as well as a “bubbliography” and a list of internet resources.
  • The Physics of Life

    At Physics.orgyou can explore the relevance and importance of physics in all our lives with Physics Life. Playing with this fun multimedia site shows you the influences and applications of physics in everything from the skateboarding to kitchen appliances.” Go explore!

    The site uses an “EasyAsk” interface to answer your physics-related questions with links to “relevant and accurate web sites from its database of refereed resources. If you provide your age and extent of your knowledge in physics, the site tailors its answers to your questions.

    This site also hosts the constants and equations page, “one of the most popular web sites on physical constants…a vital reference for anyone interested in physics – from a school student to a professor.

    The Physics of Baseball

    Want to find out more about about the physics behind the great American past time? Then, here are a few sites where you can learn more:

    1) Baseball: The Game and Beyond

    Have you ever wondered why a curveball curves, or how ERA is calculated? Well in this site we try to answer those questions along with many more. You can learn how to score a game and study the physics behind baseball. You can even hear Red Sox PA Announcer Ed Brickley’s impressions of the game.

    2) San Francisco’s Exploratorium presents The Science of Baseball

    This site has exhibits, articles and activities related to the science behind the game of baseball…as well as links to many other baseball-related web sites.

    3) The Physics of Baseball

    A professor of physics from the University of Illinois at Urbana-Champaign has a site devoted to the physics of baseball, complete with info about corked bats, wood vs. alumninum bats, the dynamics of the baseball-bat collision, characterizing the performance of baseball bats, sites geared towards younger people, Aerodynamics of the Baseball, aerodynamics of the baseball, NCAA bat standards, etc.

    Note: I would like to dedicate this post to memory of the 2003 season of the Boston Red Sox. Here’s to almost taking us to the 2003 World Series! Cheers!
