### Learning Objectives
By the end of the lesson, students will be able to:
1. Understand the basic concepts of acids and bases.
2. Identify foods that are acidic, basic, and neutral.
3. Understand the importance of balanced nutrition.
4. Gain basic digital literacy skills to assist in learning and exploring science concepts.
### Materials Needed
- pH strips or litmus paper
- Samples of household liquids (e.g., lemon juice, vinegar, baking soda solution, water)
- Nutritious food samples (e.g., fruits, vegetables, grains, protein sources)
- Computers or tablets with internet access
- Digital presentation (PowerPoint/Google Slides)
- Whiteboard and markers
- Printable worksheets
### Lesson Structure
#### **1. Introduction (10 minutes)**
- **Greeting and Attendance:**
Welcome the students and take attendance.
- **Lesson Overview:**
Briefly explain the objectives of the lesson.
“Today, we will learn about acids and bases, the importance of a balanced diet, and how digital tools can help us explore science concepts.”
#### **2. Acids and Bases (20 minutes)**
- **Introduction to Acids and Bases:**
Explain what acids and bases are. Discuss common characteristics and examples.
- **Acids:** Sour taste (e.g., lemon juice, vinegar)
- **Bases:** Bitter taste, slippery (e.g., baking soda)
- **Activity: Testing Solutions**
Distribute pH strips or litmus paper and various household liquids to groups of students.
Instruct them to test each liquid and record their observations on a worksheet.
- **Discussion:**
Explain the concept of pH scale (0-14), where 0-6 is acidic, 7 is neutral, and 8-14 is basic.
Discuss the results as a class and categorize the liquids.
#### **3. Food and Nutrition (20 minutes)**
- **Introduction to Balanced Diet:**
Discuss the importance of a balanced diet and the different food groups (carbohydrates, proteins, fats, vitamins, minerals).
- **Food Group Activity:**
Show samples of different foods and ask students to categorize them into food groups.
- **Chart Creation:**
Have students create a simple chart or drawing that represents a balanced meal, including foods from each group.
- **Interactive Digital Activity:**
Using tablets or computers, guide students to explore an interactive nutrition game or website that reinforces the lesson.
#### **4. Digital Literacy (20 minutes)**
- **Introduction to Digital Literacy:**
Explain the importance of being able to use digital tools responsibly and effectively.
- **Tech Exploration:**
Demonstrate how to use search engines and educational apps to find information related to acids, bases, and nutrition.
- **Activity: Research Task**
Assign a simple online research task where students search for acidic and basic foods and find one new fact about balanced nutrition.
- **Sharing:**
Allow students to share their findings with the class.
#### **5. Conclusion (10 minutes)**
- **Review:**
Summarize the key points covered in the lesson.
Encourage questions and address any areas of confusion.
- **Assessment:**
Distribute a worksheet combining multiple-choice questions and short answers to assess understanding of acids and bases, nutrition, and digital literacy.
- **Homework:**
Assign a simple task where students keep a food diary for a day and categorize their meals into food groups. Ask them to find one new website or app that relates to science or nutrition.
#### **6. Wrap-up (5 minutes)**
- **Reflection:**
Ask students to share what they enjoyed most about the lesson and one new thing they learned.
- **Goodbye:**
Thank the students for their participation and remind them to bring their food diaries and research for the next class.
