Have you ever cooked a marshmallow in a microwave? In case you are not familiar with this experiment, when a marshmallow is heated in a microwave, gases trapped in the marshmallow expand and escape. When the gas molecules escape from the marshmallow, they push against the marshmallow, causing it to expand. Check out the video.

Energizer Lab - A Target Inquiry Activity

This lab was written as part of the Target Inquiry program at Grand Valley State University in Michigan. Students build an electrochemical cell, learn about the symbolic equations used in electrochemistry and manipulate a model representing the particulate level of what is happening during the electrochemical process.
