In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.

In this activity, learners build a recording timer made from simple materials (e.g., small dc motor, sharpie pen, craft sticks, adding machine paper tape, etc.).

In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.
