What's so interesting about frozen water?

Switzerland has been in the deep freezer until a few days ago, so ice has been an interesting and timely subject, though we've seen too much of it.  ISOCS Junior Primary Class was investigating water until recently, so when I saw these videos about ice, I wanted to share them here.

The National Purblic Radio (US) program Science Friday recently posted this video, as a part of this broadcast.

The Secret Life of Ice from edvard brun on Vimeo.
Everyone knows ice is white and clear and sometimes blue. I discovered when I was working with small slices of ice sheets in polarized light that it also has a secret life -- a gorgeous spectrum of rainbow saturated colors. It also has some amazing hidden structures that shift and grow and shrink as the ice is freezing and melting. I put together a short sequence of the most dynamic transformations.

While you're looking at ice, watch this video from another Science Friday show, "Ode to Ice"

 

 "Ice can be hard to get a handle on, literally and figuratively. It can be cloudy or clear, as hard as concrete or as soft as a snowflake. Ice experts Erland Schulson, head of the Ice Research Lab at Dartmouth College, and Shintaro Okamoto, founder of Okamoto Studio in Queens, New York, have staked their livelihoods on the slippery material. We asked them what fascinates them about frozen water."
