In this activity, students are asked to create a change in air pressure using a garbage bag and vacuum cleaner, then create an illustration, model or concept map that explains what is happening.

This activity is part of the KQED Engineering Is: Bringing Fish Up from the Deep e-book. The e-book explores the science and engineering principles behind the California Academy of Sciences' portable decompression chamber, and includes videos, interactives and media making opportunities.
