( Note: I am not a science teacher and if you would like to correct or add to my explanation in the comments, I welcome it! Update: someone did! Read the comments for more scientific explanation of the refraction phenomena.) The light comes together at the focal point and beyond the focal point the image looks reversed because the light that was on the right is now on the left, and vice versa. In addition, the water acts as a magnifying glass, which bends the light toward the center. Whenever light passes from one medium into another, it refracts. In this case, light traveled from the air, through the front of the glass jar, through the water, through the back of the glass jar, and then back through the air, before hitting the picture. The science behind the water refraction experiment:

Diffraction of light is a phenomenon in which a light wave. It is defined as the bending of waves at the edges of an obstacle or through a slit into the region of geometrical shadow of the obstacle or slit.

  • Super nerdy kids ( I say that with love) can learn more about refraction of light here. Hint: Diffraction of light refers to the phenomena that occur when a wave of light encounters an obstacle or a slit generally.
  • Draw a diagram of what you think is happening to the light rays.
  • Does it make a difference if the jar is square or round? What about the size of the jar or glass?.
  • Does it make a difference how close the water is to the paper?.
  • I'm pretty sure my 6 year old believed me, but my 10 year old unconvincingly said, "It's water, mom." But then after I performed the experiment, he said, "Now try it with water." Ha! So I guess I did fool him. What happens?Īsk your kids to keep their eyes on the bars/arrows as you slowly pour the water into the jar. Place a jar or glass about 6 inches in front of the colored bars or arrows.

    It is two pages and includes the colored bars and two arrows. If you wish, you can download and print our printable. You have the option of setting up the science experiment as we did, or doing it right now with the glass of water sitting next to you! Best of all, there is almost no set up, but once I showed it to the kids, they experimented on their own and debated the reasons for the results.

    It would fit right in with our DIY science camp series, too. This water refraction science experiment has such a "wow factor" and is so quick and easy I can't believe my kids and I haven't done it before.
