SUBJECT: Agricultural Science

CLASS: JSS 2

TERM: First Term

WEEK 3

TOPIC: Farm Structures and Layout of Farm Buildings (Continued)

DURATION: 40 minutes

PERIOD: Single/Double

DATE: ……………………

REFERENCE MATERIALS:

• Agricultural Science for Junior Secondary Schools Book 2
• Lagos State Unified Scheme of Work
• Agricultural Science for Nigerian Schools by O.A. Iwena
• Farm structure charts, pictures or videos

LESSON OBJECTIVES:

By the end of the lesson, students should be able to:

1. Identify and explain different types of farm structures
2. Describe the uses of each type of farm structure
3. Differentiate between temporary and permanent structures on a farm
4. Classify farm structures according to their functions

PREVIOUS KNOWLEDGE:

Students have been introduced to the meaning, importance, and layout of farm structures.

ENTRY BEHAVIOUR:

Students observe various diagrams or pictures of farm structures and identify them.

INSTRUCTIONAL MATERIALS:

• Chart or poster showing different farm structures
• Pictures or models of barns, silos, animal pens, poultry houses, fish ponds
• Sample building materials (sticks, cement, roofing sheets, wire net, etc.)

CONTENT OUTLINE:

1. TYPES OF FARM STRUCTURES:

Farm structures can be grouped based on purpose or use. These include:

1. Production Structures

• Used for the production of animals or crops
• Examples:
  • Poultry house
  • Piggery (pig house)
  • Fish pond
  • Greenhouse
  • Rabbit hutches

1. Storage Structures

• Used to store crops, tools, and inputs
• Examples:
  • Barn (for yams and grains)
  • Silos (for storing grains like maize, rice)
  • Cribs (for maize)
  • Warehouses
  • Feed storage rooms

1. Processing Structures

• Used for processing raw agricultural products
• Examples:
  • Oil palm processing shed
  • Rice milling room
  • Garri processing unit
  • Fish drying shed

1. Service Structures

• Used to support farm operations
• Examples:
  • Irrigation canals
  • Drainage channels
  • Fences
  • Windbreaks
  • Roads

1. Residential Structures

• Provide accommodation for farm workers and supervisors
• Examples:
  • Farm houses
  • Staff quarters
  • Security posts

2. USES OF FARM STRUCTURES:

• Protection: To protect produce and animals from sun, rain, and thieves
• Storage: For keeping grains, fertilizers, tools, and chemicals
• Shelter: For farm workers and livestock
• Processing: To handle and prepare agricultural products
• Management: To organize farm operations properly

3. CLASSIFICATION OF STRUCTURES BASED ON DURATION:

Farm structures can also be temporary or permanent.

1. Temporary Structures:

• Can be removed or changed easily
• Often made with local or light materials
• Examples:
  • Bush fences
  • Shade sheds
  • Huts
  • Wooden cribs
  • Tarpaulin-covered storage

1. Permanent Structures:

• Built to last long (5–20 years or more)
• Made with cement, bricks, iron, and other durable materials
• Examples:
  • Concrete silos
  • Brick barns
  • Permanent irrigation canals
  • Greenhouses
  • Fish ponds with concrete walls

LESSON DEVELOPMENT:

Step 1: Introduction (5 mins)

• Begin by reviewing the previous lesson (definition and importance of farm structures).
• Ask: “What structures can be found on a poultry farm? Why are they needed?”

Step 2: Explanation and Examples (15 mins)

• Explain the five main types of farm structures.
• Display pictures or charts to show real-life examples.
• Highlight the difference between temporary and permanent structures.
• Engage the class in identifying the material used for each structure.

Step 3: Group Discussion (10 mins)

• Divide class into 5 groups, assigning one type of structure per group.
• Each group will list examples and explain the use of their assigned structure.
• Groups share findings with the class.

Step 4: Summary and Note Taking (5 mins)

• Summarize all discussed types and uses of farm structures.
• Emphasize the classification by function and by duration.
• Let students copy the notes.

CLASS ACTIVITY:

• Match the following structures with their uses:

1. Silo → ?
2. Fish pond → ?
3. Crib → ?
4. Poultry house → ?
5. Barn → ?

• Practical: Identify whether each structure is temporary or permanent based on material (chalkboard activity)

EVALUATION/ASSESSMENT:

Ask students the following questions:

1. Mention five types of farm structures and give one example of each.
2. What are the uses of farm structures?
3. What is the difference between a temporary and a permanent farm structure?
4. Classify the following as temporary or permanent: silo, bush fence, tarpaulin shed, concrete pond, wooden hutch.

SUMMARY:

• There are different types of farm structures based on their use: production, storage, processing, service, and residential.
• They can also be temporary or permanent based on materials and purpose.
• Farm structures are essential for effective and organized farm management.

ASSIGNMENT:

1. Draw a table showing 5 farm structures, their uses, and whether they are temporary or permanent.
2. List 3 materials used in constructing each of the following:
   Fish Pond
   b. Poultry house
   c. Barn
