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

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.
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.

Project: Polarizing Cellophane Tape
This special cellophane tape exhibits brilliant colors when placed between two polarizing filters. When one filter is rotated, the colors change. Beautiful cellophane images can be produced which can only be seen when placed between two polarizing filters.
Video: Electric Buzzaloo: How Bees See the Invisible
Bees are amazing social insects, and their relationship with flowers is one of nature's coolest examples of "mutualism". It got me wondering: How do bees see the world? Enjoy this look at how bees see in ultraviolet and even sense electric fields!
