A – Clay soil
B- Sandy soil


Cylinder A:
Percentage of water retained = (Water collected / Water added) x 100
= (10 cm³ / 30 cm³) x 100
= 33.33%

Cylinder B:
Percentage of water retained = (Water collected / Water added) x 100
= (25 cm³ / 30 cm³) x 100
= 83.33%

A – wheat, barley,oats

B – Carrots, radishes, sweet potatoes


I. Incubator:
Use: It is used for hatching eggs by providing a controlled environment with a specific temperature and humidity.

II. Panga:
Use: It is often used for cutting vegetation, clearing land, and harvesting crops.

III. Syringe and Needles:
Use: It is used for administering medications, vaccines, or other medical treatments.

IV. Feedrack
Uses: It is used to hold and dispense animal feed

V. Weighing Balance
Uses: It is used to measure quantities of seeds, fertilizers, or other materials, ensuring accurate and consistent application in farming practices

The seeds are planted in the farm tool containing the required soil. The set up is placed in the sun with frequent supply of adequate water. After leaving for few weeks,the seeds starts to germinate and it’s then transplanted to the field properly.


Plant Population=
Area of farmland/spacing

Plant population= (3 hectares × 10,000m²/hectare)/ 1m × 0.5m

Plant population= 10,000m²/0.5m²

Plant population= 60,000

Land area: 5 hectares= 50,000m²
Spacing: 1m×1m = 1m²
Germination Percentage: 90%

Plant population(maize) = (50,000m²/1m²) × (90/100)

Plant population= 50,000 × 0.9

Plant population= 45,000
