Class: Agricultural Science
Grade: Primary 5
Duration: 45 minutes
Objective: To introduce and explain post-harvest activities, focusing on sorting, grading, and storage.
Materials:
- Samples of harvested crops
- Sorting and grading tools (baskets, scales)
- Storage containers (silos, bins)
- Whiteboard and markers
Introduction (5 minutes): Discuss the importance of post-harvest activities in agriculture. Emphasize that what happens after harvesting affects the quality and value of the crops.
Step 1: Definition and Importance (10 minutes): Define post-harvest activities, highlighting sorting, grading, and storage. Discuss why these activities are crucial for preserving crops and maintaining their market value.
Step 2: Sorting (15 minutes): Explain the process of sorting, where harvested crops are separated based on size, color, and quality. Demonstrate how to use tools like baskets and conveyor belts for efficient sorting.
Step 3: Grading (10 minutes): Introduce the concept of grading, emphasizing the classification of crops into different quality categories. Discuss how grading influences pricing and market demand.
Step 4: Storage (10 minutes): Discuss various storage methods such as silos, bins, and warehouses. Explain the importance of proper storage in preserving the quality of harvested crops and preventing spoilage.
Teacher’s Role:
- Facilitate discussions on the significance of post-harvest activities.
- Demonstrate sorting and grading techniques.
- Emphasize the impact of storage on crop quality.
Assessment: Evaluate students based on their participation in discussions, understanding of sorting and grading processes, and their ability to explain the importance of proper storage.
Conclusion (5 minutes): Summarize key points about sorting, grading, and storage. Reinforce the idea that post-harvest activities contribute to food quality and availability.
Homework or Assignment (5 minutes): Assign a task where students research and create a simple plan for post-harvest activities for a specific crop. Encourage them to consider sorting, grading, and storage methods
