The Science of Snow and Ice
How to Survive the Snow and Ice is a new compilation video published on the Reactions YouTube channel. The video features segments about how snow (both natural and man-made) is formed, how ice is made, why saltwater takes longer to freeze than freshwater, and why kitty litter is better than regular sand for getting traction on ice.
I spent the morning skiing and playing in the snow with my daughters. That’s how we survive the snow and ice. If you’re looking for some outdoor activities to do in the snow, take a look at this list.
Here are three more videos about the science of snow and ice:
How to Make Snow (If You’re Not Elsa) is a short video produced by SciShow that explains how snow is made at ski resorts by using cooled water and compressed air.
Reactions, a YouTube channel that produces lots of science videos, has a short video that explains how snowflakes are naturally created.
The National Science Foundation has a neat video that explains how high speed cameras capture images of snowflakes forming. The video then goes on to explain why some snow is light and fluffy while other snow feels wet and heavy. (Jump to the 4:25 mark to get to the section about the formation of snowflakes).
