Interpreting Wave-Particle Duality Using Scientific Models

The Black Box is a simple and compelling demonstration that introduces students to the power of scientific models. Using this model-based perspective, students construct ideas about the behaviour of classical particles and waves. Students apply their ideas to predict the behaviour of light and electrons and verify their predictions using the included videos.
