### **Lesson Structure:**
#### **Introduction (10 minutes):**
- Greetings and a brief overview of the lesson.
- Icebreaker question: "Who can think of everyday tools we use to make work easier?"
#### **Part 1: Levers (25 minutes):**
**Explanation:**
- Define what a lever is: A rigid bar resting on a pivot, used to move a load with the application of force.
- Describe the three classes of levers:
- **First-Class Lever:** Fulcrum in between effort and load (e.g., seesaw).
- **Second-Class Lever:** Load between fulcrum and effort (e.g., wheelbarrow).
- **Third-Class Lever:** Effort between fulcrum and load (e.g., tweezers).
**Activity:**
- Demonstrate using a simple model.
- Show pictures/slides of each class of lever and real-world examples.
- Group activity: Students classify given examples into the correct lever class.
**Assessment:**
- Quick worksheet with questions about lever classes.
#### **Part 2: Food and Nutrition (25 minutes):**
**Explanation:**
- Define nutrition and its importance for health.
- Discuss the main food groups:
- Carbohydrates
- Proteins
- Fats
- Vitamins and minerals
- Water
- Importance of a balanced diet: Eating from all food groups to maintain good health.
**Activity:**
- Show pictures of balanced and unbalanced meals.
- Group activity: Given a list of food items, students create a balanced meal.
**Assessment:**
- Quick quiz on identifying food groups and reasons for a balanced diet.
#### **Part 3: Large Scale Applications of Computers (20 minutes):**
**Explanation:**
- Describe how computers are used in various fields:
- Healthcare (e.g., patient records, medical research)
- Education (e.g., online learning, digital libraries)
- Business (e.g., inventory management, online banking)
- Entertainment (e.g., games, films)
- Transportation (e.g., GPS, traffic management)
**Activity:**
- Show examples/pictures of each application.
- Group discussion: How would life be different without computers?
**Assessment:**
- Handout: Match the application to its description.

### **Conclusion (10 minutes):**
- Recap the key points covered in the lesson.
- Answer any remaining questions.
- Assign homework: Create a poster showing at least one application of each topic learned today.
**Homework:**
- Poster project showcasing levers, a balanced meal, and applications of computers.
