**Lesson Structure:**
### Part 1: Harmful Foods (30 minutes)
**1. Introduction (5 minutes):**
- Brief discussion about types of food.
- Ask students what they think is healthy and unhealthy food.
**2. Explanation (15 minutes):**
- Show images of harmful foods (e.g., junk food, sugary drinks, processed snacks).
- Discuss why these foods are harmful (e.g., high sugar content, unhealthy fats, lack of nutrients).
- Explain the health effects (e.g., obesity, tooth decay, diabetes).
**3. Activity (10 minutes):**
- Split students into small groups.
- Each group creates a chart listing harmful foods and their negative effects.
- Groups share their charts with the class.
### Part 2: Spread of Diseases (30 minutes)
**1. Introduction (5 minutes):**
- Ask students what they know about diseases.
- Discuss common illnesses (e.g., the flu, common cold).
**2. Explanation (15 minutes):**
- Explain how diseases spread (airborne, contact, contaminated food/water).
- Discuss preventive measures (hand washing, vaccinations, proper food handling).
- Use visuals or short video clips to illustrate points.
**3. Activity (10 minutes):**
- Conduct a "germ spread" demonstration using glitter.
- Spread glitter on one student’s hand (representing germs) and show how it spreads through touch.
- Discuss the importance of hygiene practices to prevent the spread of diseases.
### Part 3: Introduction to Microsoft Excel (30 minutes)
**1. Introduction (5 minutes):**
- Briefly explain what Microsoft Excel is and its uses (storing data, making tables, performing calculations).
**2. Demonstration (15 minutes):**
- Use a projector to show Excel on the screen.
- Demonstrate how to enter data into cells.
- Show how to perform basic functions (addition, subtraction).
- Create a simple table with the class (e.g., track daily water intake).
**3. Hands-On Activity (10 minutes):**
- Give students a handout with simple Excel commands.
- Have students follow along on their devices (if available) or relate activities on paper.
- Assign a basic task (e.g., inputting data and performing a simple sum).
---
**Assessment:**
- Students will be asked to list harmful foods and their effects.
- Students will demonstrate knowledge on the spread of diseases through group discussions.
- Students will complete a simple data entry task in Excel during the hands-on activity.
---
**Conclusion (5 minutes):**
- Recap key points from the lesson.
- Answer any remaining questions.
- Encourage students to share what they learned with family and friends.
---
**Follow-Up Activities:**
- Assign students to track their healthy eating for a week in a simple Excel spreadsheet.
- Conduct a quiz on harmful foods and disease prevention next week.
- Plan a more advanced lesson on Microsoft Excel to build on today's foundation.
