I. Naturally white

There are multiple instances of pure white color in natural settings. 

From clouds, to snow, to whitewater, and sea foam.  To whipped egg whites, mynah bird feathers, and a beer head. To soap foam, frothy saliva, and ice cubes.

Disorganized packets of air molecules

The first lesson highlights multiple entities that appear pure white within our natural surroundings. 

And the unifying concept behind the white color.

What holds air bubbles in place?

Most of the objects that are pure white in nature are due to masses of air bubbles that are held in place by a transparent netting. 

This allows light to be bounced around by the different reflective surfaces.

II. Variations on white

Let's start asking questions to better understand the concept of white color in nature:

- Why are clouds pink at sunset?

- Why do clouds have dark underbellies?

- How can you produce clear ice cubes?

- And others

More reasons why objects are white

Bouncing light waves off air/gas molecules is a primary reason that objects are white in nature.

However, there are others.

Ermine, Arctic hares, and Beluga whales

If mynah bird feathers are white because of disorganized air molecules within the shafts of the feathers,  what about other creatures?

Is there a common theme to having whiteness in living creatures?
