Eagle Ridge Alum Returns for a Rockin' Experiment

Erich Fietkau, an Eagle Ridge alum himself and current student at Baldwin High School, came back to help our 1st graders conduct a series of rockin' experiments via string and percussion instruments! He helped our students understand how sound is caused, by vibration, and how it travels through its surroundings, by waves. Students held balloons and could feel the vibrations of the instruments coursing through both the balloons and their bodies!
