Lesson Plan for Primary 4 - Basic Science and Technology - armful Foods + Spread Of Diseases + Launching Of

### Lesson Plan: Basic Science and Technology for Primary 4 #### Topic: Harmful Foods + Spread of Diseases + Introduction to Microsoft Excel --- **Duration:** 90 minutes **Objective:** 1. Identify different types of harmful foods and their effects on health. 2. Understand how diseases spread and methods to prevent them. 3. Learn the basics of Microsoft Excel, including simple data entry and basic spreadsheet functions. --- **Materials Needed:** - Chart papers - Markers - Printouts/photos of harmful foods - Projector and computer with Microsoft Excel - Sample spreadsheet for demonstration - Handouts with basic Excel commands and functions --- **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. --- This lesson plan ensures that students have a well-rounded understanding of basic health and technology skills, integrating practical activities to reinforce learning.
