I use YouTube for a lot of different art techniques as well as our homeroom time we call SOAR, the lessons I teach are about culture. One of the projects we do in art class is a paint pour and I love to show the different techniques by BR Turner ART. A culture lesson we just did was on words matter so I showed the students a few videos on how plants were affected by mean words and nice words, the IKEA video was pretty impactful:
