**Lesson Plan: Making of Petroleum Jelly**
**Grade Level:** Primary 6
**Subject:** Prevocational Studies
**Topic:** Making of Petroleum Jelly
**Duration:** 60 minutes
**Objective:**
By the end of this lesson, students will be able to:
1. Identify the ingredients and materials needed to make petroleum jelly.
2. Understand the process involved in making petroleum jelly.
3. Demonstrate the steps to make petroleum jelly.
4. Appreciate the importance and uses of petroleum jelly.
**Materials:**
- Whiteboard and markers
- Chart paper and markers
- Prepared sample of petroleum jelly
- Ingredients: Petroleum base (e.g., Vaseline), beeswax, essential oils (optional for fragrance)
- Equipment: Stove or hot plate, double boiler, mixing spoons, small jars or containers for storing the finished product
**Procedure:**
**Introduction (10 minutes):**
1. **Greeting and Roll Call:** Start with a warm greeting and take attendance.
2. **Introduction to Topic:** Begin by asking students if they have ever used petroleum jelly and what they use it for. Introduce the topic and explain what petroleum jelly is and its common uses (e.g., moisturizing skin, healing minor cuts and burns).
3. **Objectives:** Clearly outline what students will achieve by the end of the lesson.
**Instructional Input (20 minutes):**
1. **Ingredients and Materials:** Discuss the ingredients needed to make petroleum jelly:
- Petroleum base (e.g., Vaseline)
- Beeswax (for a firmer consistency, if desired)
- Essential oils (optional for fragrance)
2. **Demonstrate the Process:**
- **Step 1:** Melt the petroleum base in a double boiler over low heat.
- **Step 2:** Add beeswax to the melted petroleum base (about 1 tablespoon of beeswax per cup of petroleum base) if a firmer consistency is preferred.
- **Step 3:** Stir the mixture continuously until the beeswax is completely melted and combined.
- **Step 4:** Add a few drops of essential oil for fragrance, if desired.
- **Step 5:** Carefully pour the mixture into small jars or containers and let it cool and solidify.
3. **Safety Precautions:** Emphasize the importance of safety when working with hot materials. Explain how to handle the stove or hot plate and the need for adult supervision.
**Guided Practice (20 minutes):**
1. **Group Activity:** Divide students into small groups of 4-5. Provide each group with the ingredients and materials.
2. **Hands-On Making:** Each group will follow the steps demonstrated to make their own petroleum jelly. Move around the classroom to assist and supervise.
**Assessment & Reinforcement (10 minutes):**
1. **Group Discussion:** Once the students have completed their petroleum jelly, bring the class back together.
- Ask each group to share their experience and any challenges they faced.
- Discuss the importance of each ingredient and what could be adjusted if the consistency isn't as desired.
2. **Q&A Session:** Allow students to ask any questions they might have about the process.
**Conclusion (5 minutes):**
1. **Summary:** Recap the steps involved in making petroleum jelly and its uses.
2. **Cleanup:** Ensure all materials are cleaned up and stored properly.
3. **Homework Assignment:** Ask students to write a short paragraph about what they learned and how they might use petroleum jelly in their daily lives.
**Evaluation:**
- Observe students during the hands-on activity to assess their understanding and ability to follow instructions.
- Evaluate the completeness and accuracy of their individual homework assignments.
**Additional Resources:**
- A video demonstration of making petroleum jelly, if available.
- Printouts of the recipe and steps for making petroleum jelly.
**Teacher's Notes:**
- Ensure all students are engaged and participating in the hands-on activity.
- Be prepared to assist with safety-related issues, particularly with the use of the stove or hot plate.
