SYNOPSIS

In this physical science unit on the particulate nature of matter, students explore the phenomenon of fog with the goal of designing and building an affordable and safe fog machine. The goal motivates students to figure out more about natural fog through a series of investigations related to weather data and properties of air and water. Their discoveries help them develop particle-level concepts related to temperature, thermal energy, and phase changes. These understandings help students explain how natural and artificial fog are formed and how these explanations inform their engineering designs.
