Question
By the end of the lesson, students can be able to:
1. Define chemical and physical changes using simple terms.
2. Differentiate between physical and chemical changes based on their key characteristics.
3. Classify observed changes during an experiment (e.g. Candle burning) as physical or chemical, and justify your classification with reasons.
note: use the above lesson objectives to write short and brief lesson reflection on my weakness and strength and how i can improve on the next lesson if i thought the lesson based on the ytopic chemical and physical changes

**Lesson Reflection: Chemical and Physical Changes**
**Strengths:**
1. **Clarity of Definitions:** I successfully introduced clear and simple definitions of chemical and physical changes, which helped students grasp the basic concepts quickly.
2. **Engagement Through Examples:** Utilizing the candle burning experiment engaged students effectively. They were interested and participated actively in discussing the changes observed.
**Weaknesses:**
1. **Differentiation Challenges:** Some students struggled to differentiate between key characteristics of physical and chemical changes. My examples, although clear, may not have provided enough variety for full understanding.
2. **Justification of Classifications:** A few students had difficulty justifying their classifications during the experiment. I realized I could have provided more guided practice in reasoning.
**Improvements for Future Lessons:**
1. **Diverse Examples:** In the next lesson, I will incorporate a broader range of examples beyond the candle experiment (e.g., ice melting, rust formation) to strengthen students' understanding and differentiation of the two types of changes.
2. **Guided Practice Sessions:** I plan to include more collaborative group activities where students can discuss and justify their classifications in pairs or small groups, allowing for peer explanations and reinforcing understanding collaboratively.
3. **Quick Assessments:** Implement formative assessments, such as exit tickets, to gather information on students’ understanding of the topics on a day-to-day basis. This will help address any misconceptions promptly.
Overall, while the lesson had strong components, I recognize the need for more varied examples and collaborative reasoning sessions to enhance understanding and classification skills in future lessons.
