#### Lesson Outline:
1. **Introduction (10 minutes)**
- **Warm-Up**: Engage students with a short discussion on what they already know about cleaning agents. Ask questions like "What cleaning agents do you use at home?" and "Why is it important to have clean homes?"
- **Objective Overview**: Explain the objectives of the lesson and what they will be learning and doing.
2. **Theoretical Background (10 minutes)**
- **Basic Principles**: Explain the purpose of cleaning agents (removing dirt, germs, and stains to maintain hygiene).
- **Common Ingredients**: Introduce common ingredients such as vinegar (acidic, disinfectant), baking soda (mild abrasive, deodorizer), and essential oils (fragrance, additional cleaning properties).
- **Safety Precautions**: Discuss the importance of measures like wearing gloves and goggles, proper ventilation, and safe storage.
3. **Demonstration (15 minutes)**
- **Step-by-Step Process**: Demonstrate how to produce a simple all-purpose cleaning agent. For example:
- Measure 1 cup of vinegar.
- Add 1 cup of water.
- Mix in 1 tablespoon of baking soda.
- Add 10 drops of an essential oil of choice.
- Stir the mixture thoroughly.
- Pour into a spray bottle and label it.
4. **Hands-On Activity (20 minutes)**
- **Group Activity**: Divide the class into small groups. Provide each group with the materials and ingredients.
- **Task**: Have each group produce their own cleaning agent by following the demonstrated steps.
- **Supervision**: Walk around to assist and ensure all groups are adhering to the safety guidelines.
5. **Clean-Up and Labeling (5 minutes)**
- **Labeling**: Each group labels their spray bottle with the name of their cleaning agent and the date.
- **Clean-Up**: Ensure all materials are cleaned up and put back in place.
6. **Conclusion and Evaluation (5 minutes)**
- **Review**: Briefly review the key points of the lesson. Ask a few students to share what they learned.
- **Q&A**: Address any questions or concerns from the students.
- **Feedback**: Provide feedback on their participation and the cleaning agents they produced.
- **Assignment**: Give a short assignment to research and write about another homemade cleaning agent, its uses, and the benefits of making cleaning agents at home vs. buying them.
