A "Sound" Investigation of Batteries


In this activity, students will learn the fundamentals of batteries, what they are made of, and how sound waves are affected by battery materials. Batteries are key energy storage technologies for our portable electronics and electric vehicles but are very complex devices. They are difficult to measure because the materials are enclosed inside a rigid container. Ultrasounds can be used to send sound waves through the battery to understand its state of health and mechanical properties. Students will observe how the sound wave changes as it is passed over the battery.

Columbia Engineering Outreach Programs aim to provide greater accessibility to academic and professional opportunities in science, technology, engineering, and mathematics (STEM) disciplines, especially for traditionally underrepresented local stakeholders. Through community engagement, we enhance the quality and reach of learning at all levels.

Our updated Inside Engineering program now brings Columbia Engineering lab content straight to you! These now are featured in the format of hands-on, engaging engineering design activities and lessons that you can do right in your own homes or classrooms.

The Engineering Speaks program now accommodates remote sessions that allow K-12 students to hear directly from engineers from Columbia University, through virtual panels, workshops, and seminars.
