This article describes a series of activities that explore macroscopic and particulate properties of matter. The series of lessons provided follow the 5E model of learning. These activities use modeling to help students make the transition between microscopic to macroscopic using physical and analogic models. Each activity is described. Using this series of activities it is hoped that students can develop new ways of thinking beyond observations at the macroscopic scale. The different techniques used within each of the five stages make this lesson particularly interesting.

Students would have to have prior knowledge of solutions to understand the lab activity, and tie the lesson together. The lesson is good conceptually, but more concrete examples and activities are needed.
