Student interest in science has been amplified at one elementary school. During a recent unit on sound, students in a fourth-grade class participated in a series of dynamic sound learning centers followed by a dramatic capstone event— an exploration of the amazing Trashcan Whoosh Waves. It’s a notoriously difficult subject to teach, but this hands-on, exploratory approach ignited student interest in sound, promoted language acquisition, and built comprehension of key science concepts. These successful experiences with fourth-grade students are shared here.
