• 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

• 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.
