States of Matter & The Kinetic Molecular Theory: Liquids

In this lesson, students will apply the Kinetic-Molecular Theory of Liquids to the particular properties of liquids: fluidity, compressibility, density, diffusion, surface tension, and capillary action. The lesson includes an editable, animated PowerPoint introducing the basic assumption behind the Kinetic-Molecular Theory that all particles of matter are in constant motion. Vaporization, evaporation, and boiling are compared at the end of the lesson in order to have these straight before going into phase changes. NGSS: HS-PS2 Structure & Properties of Matter HS-PS1-1: Describe and classify different kinds of materials by their observable properties. DCI: PS1.A: Different kinds of matter exist and many of them can be either solid or liquid, depending on temperature. Matter can be described and classified by its observable properties. Science & Engineering Practices—Constructing Explanations: Make observations to construct an evidence-based account for natu
