**Lesson Structure:**
**1. Introduction (15 minutes)**
- **Greetings and Attendance**: Take attendance and greet the students.
- **Hook**: Show a short, engaging video that demonstrates an exciting application of chemistry (e.g., creating biodegradable plastics).
- **Objective Overview**: Discuss what the students will learn and why it’s important.
**2. Lecture (20 minutes)**
- **Definition and Scope of Applied Chemistry**: Discuss what applied chemistry is and how it differs from pure chemistry.
- **Industry Applications**: Present examples of applied chemistry in industries such as pharmaceuticals, agriculture, energy, and materials science.
- Pharmaceuticals: Drug design and development
- Agriculture: Fertilizers and pesticides
- Energy: Renewable energy sources and battery technology
- Materials: Development of new materials like polymers and nanomaterials
- **Environmental Chemistry**: Explain how chemistry is used to address environmental problems like pollution control, waste management, and water treatment.
**3. Interactive Discussion (15 minutes)**
- **Open Floor Discussion**: Encourage students to share their thoughts on where they think applied chemistry plays a role in their daily lives.
- **Case Studies**: Review a couple of short case studies that show how chemists have solved real-world problems.
**4. Group Activity (20 minutes)**
- **Lab Safety Overview**: Briefly review lab safety rules and the importance of safety in chemical applications.
- **Simple Experiment**: Demonstrate a simple chemical reaction, such as combining vinegar and baking soda to inflate a balloon, emphasizing its real-world applications like in baking and fire extinguishers.
- **Group Work**: Split the class into small groups to conduct the experiment and fill out a worksheet analyzing the reaction.
**5. Real-world Example Analysis (10 minutes)**
- **Handout Activity**: Distribute handouts with descriptions of various applied chemistry scenarios.
