Lesson Content
How To Grow Crops; Post-Harvest Activities
After crops are harvested, they must go through several activities to ensure they remain good for eating or selling. These activities are called post-harvest activities and include processing and preservation.
Processing: This means that the harvested crops are prepared for use. For example, maize must be shelled to remove the kernels from the cob. This step is necessary to make the crop ready for cooking or selling.
Preservation: This refers to how we store the crops to keep them from spoiling. Some common methods include drying the crops in the sun or storing them in airtight containers. Proper preservation ensures that the food remains safe to eat for a longer time and reduces wastage.
Lesson Evaluation:
To evaluate the learning, the teacher asks pupils to:
- What are post-harvest activities?
- Mention two reasons why processing is important after harvesting crops.
- List three methods used to preserve crops.
- Why is it important to preserve crops after harvesting?
