The document outlines activities for students to investigate food packaging materials and their environmental impacts. It also describes the design of a "Hot/Ice box" packaging project. The project aims to design packaging that can keep food hot or cold for long periods of time during travel. Students tested different materials to identify those that best protected tomatoes from damage during drops. Their final design used corrugated wrap, foam, and biodegradable materials. They concluded the design met people's needs to safely transport hot or cold food long distances.
