How loud is too loud? With the help of scientific tools, students measure sound, learn about decibels and make models of the inner ear. They’ll also examine how sound travels and learn how to protect their hearing for years to come. This class was developed in cooperation with Oregon Health & Science University (OHSU). Topics include hearing health, physics of sound, sound measurement and anatomy.

Experience an adventure in science without leaving the classroom. These programs include a general introduction to a science topic and hands-on, interactive activities.

A minimum of 2 weeks' advance notice is required for all registration requests. If you have questions, please contact us at 503.797.4661 or
