Squeeze the Stream

In this activity related to flight, learners build a tiny stream channel to investigate how fluids (air and water) change speed as they flow between and around objects. It includes an explanation "What's Going on? The Simple Explanation..." for an introductory explanation. See related resource "What's Going on? The Advanced Explanation..." for an explanation of what is happening to the water and pressure during this experiment as well as how it relates to airplanes and flight.
