The principal reason it transforms is that water is a collection of molecules, H2O, every child learns that.And that bond has the property that as the bonds get stronger when you cool water, the ice expands.

I love ice, when I was in Antarctica many decades ago, I got to see a lot of ice. And the one thing that impressed me -because I love to talk about ice - is that it has a color.

Ice is remarkable in many ways. A simple experiment one can do at home is to add salt to an amount of water in different concentrations. For example, one can mimic the concentration of the ocean, or one can make it even saltier.

People tend to romanticize what they can't quite remember.

Form follows finances instead of function.

Normally, you would not call ice a mineral.

I think the most remarkable thing about ice, in my opinion at least, is that it occurs in many, many, many different forms. Most solids occur in typically one or maybe two or three different forms, and ice has approximately 15 different crystal forms, as well as two forms that are called amorphous, which means without any shape at all.
