Informative handouts can be put at the beginning of the playlists to help students and parents stay on track and on time.
Possible pre-lab instead of demonstrating equipment in class.
Gone for a video? Put them online - if they were worth the class time, make sure everyone has access.
Student projects rather than all standing in class. Screen recordings should also be required.
Three class activities all on equilibrium. Large class sizes require spreading out labs but not wasting instructional time.
All of the worksheet problems have been worked out on video. Since practice and problems are all similar, use some that have already been done well and in your style.
Easy review using other resources and handouts for students. Why reinvent the wheel?
