Learning Activity 4.3.A: Boyle's Law for the Expanded Marshmallow

This video, published by Erie Community College, features an experiment that involves placing a marshmallow in the vacuum chamber of a Rough Vacuum System Trainer (RVET) then reducing the pressure. Elena Brewer, physics professor at Erie Community College, provides step-by-step instructions for performing the experiment and collecting data. Following the experiment, Brewer guides viewers through the process of inputting the collected data into a data table, similar to the one in the lab manual, along with completing some of the student response questions featured in section 4.3a.

This video corresponds with lessons in a student lab manual and instructor guide that accompanies the Introduction to Vacuum Technology E-book. This textbook provides an introduction to vacuum technology and science, and features topics curated to the needs of technicians in a production environment. The guides include student questions and a data table corresponding to the video.

The video runs 11:01 minutes in length. The E-book, laboratory manuals, related videos, and labs are available to view separately.
