Demonstration Videos

During the recent campus shutdown, in order to accommodate those who were teaching on-line classes, I recorded videos of demonstrations that instructors requested for use in those classes. I uploaded them to a YouTube channel on the Instructional Laboratories Group account, titled “UCSB Physics Lecture Demonstrations.” In addition to a link to that channel, I include here links to the individual videos. These are shareable links, and when you open them, the video plays through once and ends.

If you wish to copy a link, right-click the demonstration number, and from the drop-down menu that appears, select “Copy Link Location.” You can then paste the link wherever you wish.

Please note: Even though I checked all videos before I uploaded them, I sometimes found afterwards that I had made an error that compelled me to remake a video. When I did this, I deleted the original video and uploaded a new one in its stead. As a result, the link for the new video was different from that for the original one. If you copied it into a presentation for a lecture, the old link will no longer work. If this happens, please copy the new link to replace the old one. (As of 12/22/2020, this had happened for only three videos -- for two when I had just made them, and one some time later. I do not anticipate remaking any others, but if you happen to have copied an old link for one of these three, you will need to replace it with the new one.)

So that I could put them in numerical order, I made a playlist that contains the videos.  That playlist is at this link:
