Science with Steve: Why is the sky blue?

Here's another quick, simple science experiment for the kids at home!

On our way to record heat this weekend and we're stuck inside, staring at the bright blue skies from the comforts of our living rooms.

If the kids are looking for a quick science fix, here's a fun experiment to do that answers the age-old question: Why is the sky blue?

What you need:
- Water
- Milk
- Flashlight

In this experiment, the jar or glass of water will be the atmosphere and the flashlight, the sun. Put a very small amount of milk in the glass, the milk will be the gases in the atmosphere. When you shine the flashlight through the glass, there will be a faint hint of blue to the milk.

Visible light consists of all the colors of the rainbow - red, orange, yellow, green, blue and violet. Each color has a specific wavelength - red being the longest, blue & violet the shortest.

The longer wavelengths of light - reds, oranges & yellows - move through the gases in the atmosphere. At the same time, the shorter wavelengths of light, like the blues, get scattered and bounced around - making color more visible to our eyes.
