  • Article: Rudolph and relatives have UV vision

    The reindeer of the high north can see light that is invisible to our eyes. This is a big advantage in a snow white landscape. http://sciencenordic.com/rudolph-and-relatives-have-uv-vision

  • 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,…

  • Video: Wonderful experiment with polarized light

    This video is about simple experiment with polarized light. All you need is polarized glasses (for 3D films) and LCD monitor as source of polarized light. Take some transparent plastic things and get ready to say “WOW!”.

  • Video: UV Camera Shows 10 Fruits in an Amazing New Way

    For this UV video, the subject is illuminated directly by UV emitting lamps . UV filter is placed on the lens, which allows ultraviolet light to pass and which absorbs or blocks all visible and infrared light. UV filters are made from special colored glass and may be coated or sandwiched with other filter glass…

  • Video: PHYSICS GIRL EXPERIMENT- Only some humans can see this type of light

    Join Physics girl on a tour of polarized light and learn how to do a simple project to see the invisible.

  • BioSTEAM: Make an Interactive Polarized Light Visualizer!

    Pollinator eyes are specialized to see wavelengths on the electromagnetic spectrum that we can’t see like ultra violet light that helps them navigate to nectar rich flowers or even prey. Pollinators like bees, butterflies and bats can also see qualities of light that we can’t see with our eyes alone like the light polarization that…

  • Video: What Is Echolocation? | Earth Unplugged

    Echolocation allows animals to build up an understanding of their surroundings but how does it work? Find out the science of echolocation in the BBC Unplugged video.

  • 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! https://www.pbs.org/video/its-okay-be-smart-electric-buzzaloo-how-bees-see-invisible/

  • Video: Echolocation

    Are bats really blind? Not exactly. Besides their eyes, bats use a special process called echolocation to navigate their environment. Watch this video to find out how bats “see” the world around them as they look for prey in the dark. https://www.youtube.com/watch?v=laeE4icRYp4

  • 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/
