Dark Matter and Gravitational Lensing

An interactive teacher‰۪s demonstration connects circular motion to dark matter. Students are prompted to make predictions and explain the differences between their predictions and observations. The mathematical analysis activity allows students to work through calculations related to the lensing of light around massive objects and subatomic momentum collisions in a dark matter detector.
