As many as 1 in 5 people are thought to sneeze when looking at bright lights! It's known as the "photic sneeze reflex". Scientists are unsure why it happens; it's thought to be associated with nerves running between your brain and eyes.]]> 2018-03-06 07:19:43 UTC https://padlet.com/bhowes/rdhwult83g6a/wish/238471857 Light-up Trees? bhowes https://padlet.com/bhowes/rdhwult83g6a/wish/238472864 Do you like Christmas lights in trees? How about trees that light up all by themselves? Scientists at the State University of New York are developing bioluminescent trees (trees that shine all by themselves) by mixing plant and jellyfish cells!]]> 2018-03-06 07:25:31 UTC https://padlet.com/bhowes/rdhwult83g6a/wish/238472864 Jumping Jellyfish bhowes https://padlet.com/bhowes/rdhwult83g6a/wish/238474164 Did you know Jellyfish can glow in the dark? They have special chemicals in their bodies that enable them to be bioluminescent (a fancy science word meaning, "able to produce one's own light".

  • A tailor-made ABC Education transcript and video can be found here.
    • In short:
    • Create a "decoder" by placing water in a clear straw with Blu-Tack on both sides
    • Print small font-size letters on an A4 Page (ensure letters appear upside-down)
    • Place the straw decoder above the mystery letters and they appear clearly! Why?
    • When waves of light move through a clear material (i.e. a lens), the light waves can change speed/direction, i.e. refraction. This changes the way we see the light.
    • Think about a magnifying glass; the curved sense bends light outwards to make a picture seem "bigger" than it really is!
    • Place a pencil in a curved glass bowl filled with water and view it from the side, the pencil appears to "bend beneath the water" - it doesn't really bend; it's just the curved surface of the water acting as a curved lens!
    • In this experiment, the water in the straw has a curved surface, because it lies inside the straw (i.e. a plastic cylinder).
    • This "cylinder" full of water creates a cylindrical lens, which turns the image on the page upside-down when we look through!
    • We can now see the letters the right way up and decode the secret message.
