Preservation of Grains and Cereals Crops Basic 6 Agricultural Science Lesson Note

Learning Objectives: By the end of the lesson, pupils should be able to:

• Identify grains and cereal crops
• Discuss the methods of preserving grains and cereal crops
• Carry out activities of preserving cereal crops

Lesson Content:

What are Grains and Cereal Crops? Grains and cereals are seeds from grass-like plants that we eat for energy.

Examples of Grains and Cereals:

• Maize (corn)
• Rice
• Millet

• Guinea corn (sorghum)

Methods of Preserving Grains and Cereals:

1. Proper Drying

• Dry grains under the sun until moisture is removed
• Store when completely dry

2. Clean Storage

• Remove stones, dirt, and damaged grains
• Use clean containers

3. Airtight Storage

• Store in containers that don’t allow air to enter
• Use bags, drums, or silos with tight covers

4. Use of Preservatives

• Mix grains with wood ash or neem leaves
• These natural materials keep insects away

5. Regular Inspection
