  Dung Beetles use the stars to navigate. New discoveries are finding they navigate by the wind direction and solar orientation as well. Find out more in this National Geographic article.
• 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.

• Science Snack: Rotating Light
  White light is made up of all the colors in the rainbow. When polarized white light passes through a sugar solution, each color’s direction of polarization is changed by a different amount. The colors change as the depth of the solution changes or as the polarizing filter is rotated. Try it yourself in this activity from the Exploratorium. https://www.exploratorium.edu/snacks/rotating-light

• Article: How Bees See, And Why It Matters
  Scientists consider bees to be a keystone species. They are so important to an ecosystem that it will collapse without them. At least 90 commercially grown crops depend upon bee pollination for survival. How important is the pollination by bees? Ask an almond grower. Without bees, there would be no almonds. Apples, blueberries, cherries, avocados, cucumbers, onions, grapefruit, oranges and pumpkins would also disappear. Bees are the undisputed champions of the pollination world. And their secret weapon? Sight.
• Bats Use Polarized Light To Set Internal Compasses
  Although bats are known for using echolocation to orient and navigate, they draw on a suite of senses to get around. A new study reveals another ability: Bats use patterns of polarized light in the sky to navigate.

• Project: Invisible Art- Mosaics, Polarized Light, and 3D Glasses
  This simple project capitalizes on the ability of certain materials that not only polarize light but twist it, and of 3D glasses to see that light as various colors. https://www.instructables.com/id/Invisible-Art-Mosaics-Polarized-Light-and-3D-Glass/
• Project: Polarized-Light Mosaic
  Using transparent tape and polarizing material, you can make and project beautifully colored patterns reminiscent of abstract or geometric stained-glass windows. Rotating the polarizer as you view the patterns makes the colors change. https://www.exploratorium.edu/snacks/polarized-light-mosaic
• 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
