Blue Skies

Blue Skies is a science project for kids that explains how light is refracted through our atmosphere. Teach your kids how waves of light color our world.

What You'll Need:

  • Flashlight
  • Table
  • Flour

Learn About Blue Skies:

Step 1: Why is the sky blue? When the white light of the sun filters through our atmosphere, it scatters into every color of the rainbow and every possible wavelength. Our atmosphere makes it blue.

Step 2: This simple experiment will give you an idea of how that scattering works and why weather patterns can cause a colorful shift.

Step 3: Turn a flashlight on outside at night. Set the flashlight on a table so its beam shines in midair in front of you. Now sprinkle flour in front of the beam.

Step 4: You should see dozens of white flashes as each piece of flour or dust reflects light waves and sends the color signal straight to your eyes. That's how our atmosphere sends flashes of color to your eyes to make the sky seem so blue.
