🤍 A Very White Winter
When winter arrives, the world suddenly looks brighter.
Fields, trees and streets turn white.
Snow looks white from far away and up close.
But here is the big question
Why is snow white
Snow is made of ice.
Ice is clear.
So why does snow not look clear
Let us discover the science behind the color of snow.
❄️ Snow Is Made of Tiny Ice Crystals
Each snowflake is made of clear ice.
If you could hold one perfect ice crystal, you would see through it.
But snow on the ground is not one crystal.
It is made of millions of tiny crystals piled together.
That changes everything.
☀️ How Light Hits Snow
Sunlight looks white, but it is actually made of many colors.
Red, orange, yellow, green, blue and violet.
When light hits snow:
- it enters the ice crystals
- it bounces around inside
- it reflects back in all directions
Because snow has so many tiny surfaces, the light keeps bouncing again and again.
All colors are reflected almost equally.
When all colors return to your eyes together, you see white.
Professor Bubbles says
Snow is like a giant mirror maze for light
❄️ Why Ice Looks Clear but Snow Does Not
A block of ice has smooth surfaces.
Light passes through easily.
Snow is different:
- rough surfaces
- many air pockets
- lots of angles
The air trapped between snow crystals also helps scatter the light.
Clear ice plus air plus many crystals equals white snow.
🌡️ Does Snow Always Look White
Most of the time yes.
But snow can change color.
Snow can look:
- blue in shadows
- pink at sunrise or sunset
- yellow or brown when dirty
These colors happen because of:
- light angle
- shadows
- reflections
- tiny particles in the snow
But clean fresh snow is almost always white.
🐾 Why White Snow Helps Animals
White snow is important for animals.
Some animals turn white in winter:
- arctic foxes
- hares
- owls
White fur helps them:
- hide from predators
- sneak up on prey
- blend into snowy landscapes
Snow color shapes animal survival.
🧪 Snow Science Activity
Make Your Own White Test
What you need:
- a flashlight
- clear ice
- fresh snow
What to do:
- Shine the flashlight through clear ice
- Shine it onto snow
- Compare how the light behaves
You will see light pass through ice but bounce back from snow.
That is why snow looks white.
🧠 Fun Snow Facts
- Fresh snow reflects most sunlight
- Snow helps keep Earth cooler by reflecting heat
- Ski goggles are dark because snow is so bright
- Astronauts can see snowy areas from space
