Jefferson Lab’s YouTube channel includes a playlist titled Frostbite Theater. The first time I looked at the playlist a few years ago it had about fifty videos. The playlist has now expanded to 87 videos. The playlist features videos of science demonstrations and experiments. Many of the demonstrations involve the use of liquid nitrogen. You’ll also find videos about electricity, insects, and lasers. The video from the playlist that I’ve embedded below is about measuring the speed of light.

Applications for Education
Rather than just showing these videos to your students, place them into a tool like EDpuzzle or TES Teach with Blendspace to build questions into the videos. Both of those tools will let you add questions into the timeline of a video and let your students respond while watching the videos.
