The objective of this learning activity is to provide students with an introduction to using digital photography and the stroboscopic technique to measure high speed droplet size and velocity. This will be useful knowledge in applications such as "high-speed assembly lines, conveyor systems, bottling operations, printing process, turbine operations and other research setups." This eleven page document describes general Module Data, Equipment and Materials Required, and a detailed Procedure. The activity is intended for high school students with basic physics and computer knowledge.
