In this lesson, students will apply the Kinetic-Molecular Theory of Solids to the particular properties of solids: fluidity, compressibility, and density. 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. The two types of solids—crystalline and amorphous–are included in the lesson. At the end of the lesson, the four types of crystalline solids are introduced, and their melting point are compared.
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 natural phenomena.
Cross-Cutting Concepts—Patterns: Patterns in the natural and human designed world can be observed.
