Mai Lesson
Sky Color Mystery
Science · 30 min · Any age · You and your child together
This lesson uses a simple home experiment to discover why the sky appears blue, rather than green or any other color. Families will explore how light interacts with tiny particles, mimicking Earth's atmosphere, to reveal the science behind our blue skies.
What your child gets out of it
- Explain that white light is made of different colors with different wavelengths.
- Describe how light scattering makes the sky appear blue.
- Conduct an experiment to observe light scattering in a liquid medium.
What you need
- Clear drinking glass — Needs to be see-through for best results. (or Clear jar, Clear plastic cup)
- Water
- Milk — Any kind of milk will work; just a few drops are needed. (or A tiny drop of liquid hand soap, A pinch of flour (dissolved))
- Flashlight — A strong, focused beam is best. (or Phone flashlight)
- Dark background — Helps to see the scattered light more clearly. (or Dark towel, Dark piece of paper, Dark clothing)

Why it matters
Understanding light scattering helps scientists design more efficient lighting, predict weather patterns, and even study distant galaxies.
