Our library has one video camera, so I borrowed it last year. My students had done research projects (their very first), and I let them choose a topic they were interested in. I also let them choose how to present their information. A 2-3 minute commercial/"documentary" was one of the choices. About 10 students chose to present that way, and their presentations were wonderful! It was a fun way to incorporate technology and let the students think "outside the box" a bit.
Just in case you don't have a video camera to use, I remember doing something similar in high school. We used a blank cassette tape to record a "radio commercial". We played it for the class as our presentation. I remember it clearly...we were studying the 1920s. My group (me and 3 boys!) did a commercial about why people should join the women's suffrage movement
