  Abstract: This poster presentation will show how a cathode ray tube, laser pointers and an ammeter can be used to demonstrate, in "real life", the photoelectric effect. It is a simple, possibly accessible demonstration of a topic that, in high school classrooms, may otherwise only be heard about and "demonstrated" through PhET applet of the like. I have found it an exciting and attention grabbing "mystery" for my students to solve, that sets the stage for a deeper discussion of the topic.
