Why is the Sky Blue?

Sure, having a baby was scary. A few sleepless nights and a lot of soul searching later, you began to get the hang of answering their unspoken needs. And just as your new confidence began to blossom, they learned to talk, and they have questions, thousands of questions. This leaves most of us wide-eyed and dumbstruck—things just got real! Parents are the keeper of the world’s knowledge, and their child’s quest for it is inexhaustible.

Don’t worry. You got this. Until the age of 2, most little ones are making conversation, chatter. Your explanations can be conversational and even nonsensical; the goal is language development and bonding. After 2 years, they begin their scientific quest for knowledge, specifically, causality. This is the foundation of logic and is a wonderful display of your little one’s burgeoning brilliance. For the next few months, I’ll share a few of their favorite questions, WITH answers!

Question: Why is the sky blue?

Answer: From some smart folks at a place called NASA…

“The light from the Sun looks white. But it is really made up of all the colors of the rainbow. Like [wave] energy passing through the ocean, light energy travels in waves, too. Some light travels in short, ‘choppy’ waves. Other light travels in long, lazy waves. Blue light waves are shorter than red light waves. Sunlight reaches Earth’s atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered in all directions by the tiny molecules of air in Earth’s atmosphere. Blue is scattered more than other colors, because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.”                           (Source: spaceplace.nasa.gov)
