実践化学: 溶解度平衡と溶解度規則。

What Will Be Taught?
Students will:
 - Solve solubility equilibria (Ksp) problems of increasing difficulty.
 - Write dissolution equations and calculate molar solubility.
 - Connect theory to real-world applications (e.g., lab analysis).

Topics Covered
 - Ksp calculations and molar solubility.
 - Advanced problems: pH effects and common ion effect.

Class Structure
   1. Recapping important concepts (10 mins): relationships between mole, molar mass, and molarity. Defining solubility and solubility product.
   2. Direct Instruction (20 mins- divided into two sections): Mini-lecture with slides and examples to define the general guiding steps to solve solubility equilibria and molar solubility problems.
   3. Guided Practice (30 mins): Solve problems together (easy → hard).
   4. Independent Challenges (15 mins): Students work on problems with live feedback.
   5. Q&A/Discussion (15 mins): Clarify doubts and discuss real-world relevance.

Teaching Style & Interaction
   - Interactive Problem-Solving: Learn by doing! Students will actively solve problems on-screen or share their work.
   - Visual Aids: Slides, step-by-step breakdowns, and animations for clarity.
   - Scaffolded Difficulty: Start simple, then advance to Ksp solubility product indirect calculations.
   - Personalized Feedback: Individual attention during practice sessions.

Tools Used:
    - Screen-shared slides with key concepts.
    - Polls/quizzes to check understanding.
