  • Project: Light and Optics: Building the impossible kaleidoscope
    In this section we will build a toy called the Polariscope. As you can see from the above photograph, the Polariscope makes patterns of beautiful colors, somewhat like a kaleidoscope, but by an entirely different mechanism. Learn more in this lesson project by Sci-toys. https://sci-toys.com/scitoys/scitoys/light/polariscope.html
  • Video: Show Me Some Science! Polarization of the Sky
    Bees are capable of remarkable feats of orientation and navigation; they have a very strong sense of direction. Find out more in this easy experiment.
  • Activity: Twisting light
    How does a third polarizer make light pass through crossed polarizers? Find out in this activity from Cienascao. https://www.sciensation.org/hands-on_experiments/e5087p_twistingLight.html
  • Project: Locating the Sun by Polarizing Sunglasses
    Anti-glare polarizing sunglasses reduce ground reflected polarized rays. They can be used to locate the Sun even when it is hidden from view by clouds or by the horizon. In this way, they can even do the main task of "sky compass" and similar instruments. Find out how to make it yourself in this project by Industructables.
  • Project: Spy Tech- Polarized Hidden Messages
    We all know sunglasses make any spy look cool, but these will let you see secret messages! This secret message project uses polarized film (technically a linear absorptive polarizer) to make our message hidden. To see the message you either have to look through a second piece of film, or put on a pair of polarized sunglasses.
  • Student Example: Kaleidoscope
    The kaleidoscope consists of two polarized filters on top of each other. By rotating the filters the colors and composition changes because of the polarization. See this student’s example. https://www.behance.net/gallery/14306539/Kaleidoscope
  • Video: Bell's Theorem: The Quantum Venn Diagram Paradox
    This video is about Bell's Theorem, one of the most fascinating results in 20th century physics.  Learn more about polarization and quantum mechanics in this video by Minute Physics. https://www.youtube.com/watch?v=zcqZHYo7ONs
