- Periodic table images or handouts
**Class Structure**:
1. **Introduction** (10 minutes)
- Greet the students and introduce the topic.
- Briefly discuss the importance of chemistry in understanding the world around us.
- Present the objectives of the lesson.
2. **Direct Instruction** (20 minutes)
- Define chemistry: "Chemistry is the study of matter, its properties, how and why substances combine or separate to form other substances, and how substances interact with energy."
- Explain the significance of chemistry in everyday life (e.g., cooking, cleaning, medicine, environmental issues).
- Introduce the branches of chemistry:
- Organic Chemistry
- Inorganic Chemistry
- Physical Chemistry
- Analytical Chemistry
- Biochemistry
- Environmental Chemistry
3. **Activity** (15 minutes)
- Divide students into small groups and assign each group one branch of chemistry.
- Ask each group to research their assigned branch and present a short summary to the class, including real-life applications.
- Provide reference materials and handouts to assist in their research.
4. **Discussion** (10 minutes)
- Have students share their group findings and discuss the various applications of each branch.
- Emphasize the interconnectivity of the different branches of chemistry.
5. **Roles of a Chemist** (10 minutes)
- Discuss what chemists do and the various roles they play in different industries (e.g., pharmaceuticals, forensics, environmental science).
- Use examples of famous chemists and their contributions (e.g., Marie Curie, Linus Pauling).
6. **Scientific Method and Experimentation** (10 minutes)
- Explain the scientific method: Observation, Question, Hypothesis, Experiment, Data Collection, Conclusion, and Communication.
- Provide real-world examples of how the scientific method is applied in chemistry.
- Hand out the scientific method worksheet and go through an example together.
7. **Conclusion and Q&A** (5 minutes)
- Summarize the key points of the lesson.
- Answer any questions students may have.
- Provide a brief overview of what will be covered in the next lesson.
8. **Assignment** (5 minutes)

- Provide guidelines for the essay.
**Assessment**:
- Participation in group activity and class discussion.
- Completion of the scientific method worksheet.
- Quality and thoughtfulness of the homework essay.
**Differentiation**:
- Provide additional resources or simplified materials for students who may need extra assistance.
- Offer more challenging tasks or additional reading for advanced students.
**Follow-Up**:
- Review and discuss student essays in the next class.
- Begin the next lesson with a brief recap of the key concepts covered in this lesson.
**Reflection**:
