LESSON DESCRIPTION:
Using dry ice to attempt to cool 9 different materials, students observe how fast the materials respond to a change temperature.

TIME REQUIRED: One Hour

OBJECTIVES:
Students learn about how plastic, foam, and wood are good thermal insulators and how metals are good thermal conductors. This lesson demonstrates how the scientific properties of materials help determine what humans use them for.

FACILITIES REQUIREMENTS:
Tables for all participants.

SAFETY:
Participants are given a safety training on how to work with dry ice safely. Students are advised to not allow the dry ice to come into contact with their skin for more that a second. Students are advised to not press any of the cubes against the dry ice for more than 5 seconds.
