International Year of Sound 2020


Holly Fortner

Science Outreach Catalyst Kits, or SOCKs, are free to SPS chapters (while supplies last) and contain an exploratory physics and science activity that is specifically designed for SPS chapters to use in outreach presentations to elementary, middle and high school students. Each SOCK comes with the essential materials to conduct a set of demonstrations, a comprehensive manual, and instructions on how to expand the demonstration to become a tried-and-true outreach activity. It's designed for chapters just starting out or those who are demo pros. SOCKs are designed and implemented annually by the SPS National interns and SPS National office staff.

The 2020-21 SOCK is done in conjunction with the American Acoustical Society (ASA) and explores the physics of... acoustics! This kit will focus on how we can visualize sound in real time, appreciate the sounds that we make as people, and look to examine the soundscapes around us! SOCK users will be able to work with students from elementary school age (5-10) up through high school. See below for more information on the demonstrations and activities included in the SOCK.

Portable Oscilloscope and Microphone: Sound is not visible to the human eye, but have you ever wondered what sound looks like? This demonstration utilizes a portable oscilloscope to visualize sound signals! Here we will measure the electrical signals of a microphone to show people their own voices.

Longitudinal and Transverse Waves: What are waves? And, more specifically, what are sound waves? A slinky is used to explain two types of waveforms - longitudinal and transverse - while a tuning fork exhibits sound waves as longitudinal waves.
