## Lesson Structure
| Step Number | Step Title | Length | Details |
|--------------|-------------------------|-------------|-------------------------------------------------------------------------|
| 1 | Introduction to Periodicity | 5 minutes | Briefly introduce the concept of periodicity and its importance in chemistry. Discuss the periodic table layout. |
| 2 | Exploring Trends | 10 minutes | Present key periodic trends: atomic radius, electronegativity, ionization energy. Use the projector for visual aids. |
| 3 | Group Activity | 10 minutes | Divide students into small groups to analyze specific elements and summarize their trends using guided questions. |
| 4 | Class Discussion | 3 minutes | Come back together to discuss findings. Facilitate a conversation about the significance of trends in predicting element behavior. |
| 5 | Conclusion | 2 minutes | Summarize key points of the lesson and introduce the homework assignment. |
## Homework
- Complete the worksheet on periodic trends in the periodic table. Include questions that reinforce the concepts covered in class.
- The homework will be collected and graded without requiring students to present their answers in front of the class.
