About This Chapter
Below is a sample breakdown of the Phase Changes for Liquids and Solids chapter into a 5-day school week. Based on the pace of your course, you may need to adapt the lesson plan to fit your needs.
|Day||Topics||Key Terms and Concepts Covered|
|Monday||Kinetic molecular theory and phase diagrams||Explanation of the way in which matter behaves and understanding phase diagram graphs|
|Tuesday||Evaporation, condensation, freezing, melting, sublimation and deposition||A look at what happens during these processes|
|Wednesday||Finding the heat of fusion and evaporation||The process of calculating the heat of fusion|
|Thursday||Phase diagram of water compared to other substances||Exploring the differences|
|Friday||Crystal structures||Kinds of crystals and their particles|
1. The Kinetic Molecular Theory: Properties of Solids and Liquids
This lesson explores the kinetic molecular theory and how it pertains to the properties of solids and liquids. You'll learn the properties of solids and liquids, discover the types of intermolecular attractions that occur between them and gain an understanding how phase changes happen.
2. Phase Diagrams: Critical Point, Triple Point and Phase Equilibrium Boundaries
Learn what a phase diagram is and how to interpret phase diagrams. Discover how to use a phase diagram to locate the phase equilibrium boundaries. Also, learn what a triple point and critical point are and how to locate them on a phase diagram.
3. Phase Change: Evaporation, Condensation, Freezing, Melting, Sublimation & Deposition
Substances on Earth can exist in one of four phases, but mostly, they exist in one of three: solid, liquid or gas. Learn the six changes of phase: freezing, melting, condensation, vaporization, sublimation and deposition.
4. Heat of Fusion & Heat of Vaporization: Definitions & Equations
When a substance changes states, like from a solid to a liquid, a lot is happening. This lesson will examine the heat of fusion and the heat of vaporization. It will also explain both formulas.
5. Phase Diagram of Water vs Other Substances: Differences & Meaning
Phase diagrams give scientists specific information about how phase changes occur at different pressures and temperatures. This lesson examines phase diagrams, focusing on water and how it's a little different from most other substances.
6. Phase Changes and Heating Curves
Learn the phases - gas, liquid, solid and plasma. Learn what a phase diagram is and what terms describe the movement between phases: melting, sublimating, freezing, vaporization, condensation, and deposition. Discover why heating curves have plateaus, what a phase transition is, and what happens during this transition.
7. Crystal Structures and the Unit Cell
This crystallography lesson explores the structure and properties of crystals. You'll learn about the parts of a crystal structure, types of crystals and patterns created by unit cells.
8. Crystals Lesson Plan
With your guidance and this lesson plan, students will learn about the different types of crystals, their bonds, and structures. They will watch a video, participate in discussion questions, complete an activity, and take a quiz.
