For over 30 years, the Exploratorium's Teacher Institute (TI) has been the professional home for middle‐ and high‐school science and math teachers in the Bay Area and beyond. TI’s staff of PhD scientists and veteran science educators have developed over a thousand classroom activities that encourage both teachers and students to build and explore tabletop versions of Exploratorium exhibits and other hands‐on investigations of science. These activities are designed to demonstrate unusual or unexpected phenomena, spark curiosity, generate questions, and serve as the starting points for deeper classroom explorations.
