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 explore how engineering has developed various means to remove impurities from water.

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.

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.
