Analyzing real motion with frame-by-frame precision can be conducted using modestly priced digital-video camcorders. Although well below the 1,000 frames-per-second threshold of high-speed cameras, commercially available camcorders grab 30 frames per second. A replay dissected at this lower frequency is fun to watch, challenges students' perceptions, and unleashes new instructional possibilities for motion, momentum, and energy. One digital-video-based investigation uses falling dominoes to develop students' inquiry skills. Analyzing toppling dominoes in slow motion sharpens students' observations of a fairly common childhood experience and stimulates creativity for subsequent explorations within the field of mechanics. With student participation as the centerpiece, this article presents science activities that show how inquiry skills are developed, formalized, and extended using camcorder technology.
