**Lesson Duration: 90 minutes**
### Lesson Plan:
**Introduction (10 minutes)**
1. **Greeting and Roll Call (2 minutes):** Start by welcoming students and taking attendance.
2. **Introduction to Practical Lab Skills (3 minutes):**
- Briefly outline what will be covered in the lesson.
- Emphasize the importance of precision, safety, and careful observation in scientific experiments.
3. **Safety Briefing (5 minutes):**
- Discuss general lab safety rules (e.g., wearing protective gear, handling chemicals carefully).
- Highlight the location of safety equipment such as eyewash stations, fire extinguishers, and first aid kits.
**Demonstration (10 minutes)**
1. **Equipment Usage (5 minutes):**
- Demonstrate the correct usage of key lab equipment (measuring cylinders, pipettes, Bunsen burners, etc.).
2. **Accurate Measurements (5 minutes):**
- Show how to measure liquids accurately using different measuring tools.
- Explain how to weigh substances using a digital scale.
**Activity Part 1: The Simple Experiment - Measuring pH (20 minutes)**
1. **Objective and Procedure Briefing (5 minutes):**
- Explain the goal: to measure the pH of various household substances (e.g., vinegar, baking soda solution).
- Ensure students are clear about the steps they need to follow.
2. **Conducting the Experiment (15 minutes):**
- Divide students into small groups.
- Provide each group with samples.
- Allow students to use pH paper/indicators to test the samples.
- Instruct students to record their findings accurately in their lab notebooks.
**Activity Part 2: Chemical Reaction Observations (30 minutes)**
1. **Objective and Procedure Briefing (5 minutes):**
- Explain the objective: to observe and record chemical reactions by mixing vinegar and baking soda.
- Highlight what to look for (e.g., gas production, temperature change).
2. **Conducting the Experiment (20 minutes):**
- Again, divide students into small groups.
- Provide each group with the necessary chemicals (vinegar and baking soda).
- Ensure students measure and mix the chemicals as instructed, documenting their observations.
- Monitor groups for safety and accuracy.
3. **Discuss and Record Findings (5 minutes):**
- Have students share their observations and write conclusions based on their data.
**Conclusion (10 minutes)**
1. **Recap of Key Concepts (5 minutes):**
- Review what was learned about laboratory safety, equipment usage, and the importance of accurate measurements.
2. **Q&A Session (5 minutes):**
- Encourage students to ask questions about the experiments and clarify any doubts.
3. **Assignment:**
- Ask the students to write a 1-page lab report on one of the experiments conducted, including the objective, procedure, results, and conclusion.
**Homework:**
- Complete the lab report at home and prepare to discuss your findings in the next class.
### Assessment:
- Observe students during hands-on activities to assess their practical lab skills.
- Evaluate lab notebooks and homework reports for understanding and accuracy.
**Extensions:**
- For advanced students, consider introducing more complex experiments or exploring digital data collection methods in future lessons.
