Integrated Science for SHS – Full Lesson

Agriculture is a key sector in Ghana, contributing to food security, employment, and economic growth. This unit equips teacher trainees with knowledge of crop and animal production, management practices, and problem-solving in agriculture. Candidates will learn how to apply practical agricultural concepts, which is critical for the GTLE practical scenarios.


MODULE 4.1: CROP PRODUCTION

Learning Outcomes:
By the end of this module, trainees should be able to:

  • Explain the steps involved in crop production

  • Apply crop production techniques to local conditions in Ghana

  • Solve practical agricultural problems related to crop farming


Topic 1: Land Preparation

Definition:
Land preparation is the process of making the soil ready for planting crops. This involves clearing, loosening, and enriching the soil to improve aeration, drainage, and fertility.

Steps in Land Preparation:

  1. Clearing the land: Removing weeds, stones, and debris to prepare a clean area for planting.

  2. Ploughing/Tilling: Turning the soil using a hoe, plough, or tractor to loosen compacted soil. This improves aeration and allows roots to penetrate easily.

  3. Harrowing: Breaking large soil clods into finer particles for a smoother seedbed.

  4. Levelling: Flattening the land to ensure uniform water distribution.

  5. Fertilization (optional at this stage): Adding organic manure or chemical fertilizers to improve soil fertility.

Teacher Notes:

  • Emphasize that good land preparation increases crop yield by creating favorable conditions for seed germination and root development.

  • Example: Maize and cassava require deep ploughing to allow their roots to grow freely.


Topic 2: Planting Methods

Definition:
Planting methods are the techniques used to sow seeds or transplant seedlings into prepared land.

Common Methods in Ghana:

  1. Broadcasting: Seeds are scattered over the soil surface.

    • Advantages: Fast and easy

    • Disadvantages: Uneven spacing, may require thinning

  2. Drilling: Seeds are sown in rows using a seed drill or by hand.

    • Advantages: Uniform spacing, better germination

    • Disadvantages: Requires more labor or equipment

  3. Transplanting: Seedlings are first raised in nurseries and then moved to the field.

    • Example: Rice and vegetables

    • Advantages: Higher survival rate and yield

    • Disadvantages: Labor-intensive

Teacher Notes:

  • Stress the importance of spacing and depth during planting to avoid overcrowding and poor growth.

  • Practical GTLE question: Which method is suitable for rice in lowland areas?Transplanting


Topic 3: Weeding

Definition:
Weeding is the removal of unwanted plants (weeds) that compete with crops for nutrients, light, and water.

Methods of Weeding:

  1. Manual Weeding: Using a hoe or hand tools. Suitable for small farms.

  2. Mechanical Weeding: Using tractors or weeders for large farms.

  3. Chemical Weeding (Herbicides): Using safe herbicides to kill weeds.

Teacher Notes:

  • Emphasize that timely weeding reduces yield loss.

  • Weeds also host pests and diseases, so their removal improves crop health.


Topic 4: Harvesting

Definition:
Harvesting is the process of collecting mature crops from the field.

Considerations Before Harvesting:

  • Crop maturity (e.g., maize should have hard kernels, cassava roots should be 9–12 months old)

  • Weather conditions (dry weather is preferable for grains)

Harvesting Methods:

  • Manual Harvesting: Using hands or sickles (e.g., maize, vegetables)

  • Mechanical Harvesting: Using combine harvesters for grains

Teacher Notes:

  • Highlight post-harvest care: drying, storage, and pest control to prevent losses.

  • GTLE application question: If maize is harvested when still green, what will happen? → Reduced storage life and risk of spoilage.


MODULE 4.2: ANIMAL PRODUCTION

Learning Outcomes:
By the end of this module, trainees should be able to:

  • Describe types of farm animals commonly reared in Ghana

  • Apply principles of feeding, housing, and disease control

  • Solve practical problems in animal husbandry


Topic 1: Types of Farm Animals

Categories:

  1. Livestock: Animals raised for food or income

    • Examples: Cattle, goats, sheep, pigs

  2. Poultry: Birds raised for eggs or meat

    • Examples: Chickens, ducks, turkeys

  3. Others: Beekeeping (honey), rabbits

Teacher Notes:

  • Emphasize that choice of animal depends on climate, feed availability, and market demand.

  • GTLE practical scenario: Which animal is suitable for a small backyard farm in Accra? → Chickens or rabbits.


Topic 2: Feeding

Definition:
Feeding is providing animals with the right nutrients for growth, reproduction, and health.

Types of Feed:

  1. Natural Feed: Grass, leaves, crop residues

  2. Concentrate Feed: Maize bran, soybeans, commercial feed

  3. Water: Fresh and clean water is essential

Feeding Practices:

  • Ad libitum: Animals eat as much as they want (common for poultry)

  • Scheduled feeding: Animals fed at specific times

Teacher Notes:

  • Nutrition affects productivity and health. Poor feeding leads to stunted growth and low yield.


Topic 3: Housing

Definition:
Animal housing is providing a safe and suitable shelter for farm animals.

Key Features of Good Housing:

  • Protection from rain, sun, and wind

  • Proper ventilation

  • Cleanliness to prevent disease

  • Adequate space for movement

Examples:

  • Chicken coop for poultry

  • Pen for goats and pigs

  • Shed for cattle

Teacher Notes:

  • Housing directly affects animal welfare and productivity.

  • GTLE scenario: What is the purpose of ventilation in poultry houses? → To prevent respiratory diseases.


Topic 4: Disease Control

Definition:
Disease control involves preventing and managing animal illnesses to maintain productivity.

Common Farm Animal Diseases in Ghana:

  • Cattle: Foot-and-mouth disease, Black quarter

  • Goats/Sheep: Peste des petits ruminants (PPR)

  • Poultry: Newcastle disease, fowl pox

Prevention Methods:

  • Vaccination

  • Quarantine new animals

  • Good hygiene and sanitation

  • Proper feeding and housing

Teacher Notes:

  • Emphasize integrated farm management to reduce losses.

  • GTLE scenario: A flock of chickens suddenly becomes weak and stops eating. What is the first action? → Isolate sick birds and call veterinary service.


Summary Table: Crop vs Animal Production

Aspect Crop Production Animal Production

GTLE Focus:

  • Practical scenarios: problem-solving in crop/animal farming

  • Examples:
