The National Science Foundation offers a YouTube playlist of sixteen videos on the science of Winter Olympics events. These short videos teach lessons on the physics and engineering behind the events we see on television. The videos are a decade old, but the science concepts covered are just as relevant to these Olympic games as they were to previous Winter Olympics.
It's hard to host skiing and snowboarding events without a lot of snow. That's why a lot of the snow we'll see on television during the Winter Olympics is human-made snow. 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.
In the United States NBC owns the rights to nearly all Olympics-related footage and logos which is why it's a little disappointing that they don't offer more student-focused resources than this PDF guide to the Winter Olympics and some YouTube videos that aren't well organized beyond this playlist. I went through the NBC News Learn channel and highlighted a few favorites and included them below.
