Presents activities on persistence of vision that involve students in a hands-on approach to the study of early methods of creating motion pictures. Students construct flip books, a Zoetrope, and an early movie machine. (DDR)

Highlights the need to make the undergraduate physics laboratory more exciting and commensurate with the time assigned for it in the curriculum. Suggests establishing a model undergraduate physics laboratory at one place then reproducing it in five places for a massive reorientation program for teachers. Contains brief outlines of 30 experiments…
