Question 2

(a) For each of specimens H, I and J  name two farm tools that can perform functions similar to those of the specimens.                                 [3 marks]

(b)  Describe how each of specimens I and J is used.             [4 marks]
(c)   Describe each of specimens H and J.                    [4 marks]
(d)    Enumerate four advantages of using farm tools for farm work                [4 marks]                                            


This question was not popular with the candidates.  In question 2(a), majority of the candidates could not name farm tools that can perform functions similar to specimens H (Spade), I (Secateurs) and J (Open-ended spanner).  Also in question 2(b) many candidates were unable to describe how specimens I and J are used.  In question 2(c), most of the candidates could not describe specimens H and J.  Also, in question 2(d), majority of the candidates were unable to enumerate advantages of using farm tools for farm work.

The expected answers include:

Tools that can perform similar functions as specimens H, I and J
Specimen H (Spade)
-  Hoe, shovel and hand trowel             

Specimen I (Secateurs)
-   Saw, sickle, cutlass and shears                       

Specimen J (open-ended spanner)
-           Wrench, ring spanner and pliers         

How Specimen I (Secateurs) is used

  • Open the handle to widen the blades
  • Fix the opened blades against the material to be cut
  • Press back the handles to close the blades and cut the materials
  • Release the handle                                                       
How specimen J (open-ended spanner) is used
  • Fix opened and directly on top of the bolt (appropriate size)
  • Turn the handle clockwise (to tighten) or anticlockwise (to loosen) the bolt.
  • Continue to turn until the bolt is firmly fixed or loosened before releasing the handle.          
      Description of each of specimens H and J
    Specimen H (Spade)
  • Has a long wooden/metallic handle  
  • Blade is metallic (steel)
  • Blade is rectangular, flat and sharp at one end for easy penetration into the soil
  • Handle widens at the posterior end to form a triangular block or “D” shape for firm handling
    Specimen J (open-ended spanner)
  • It is metallic                  
  • Both sides end in a hexagonal shape of various sizes that fit the heads of bolts
  • Flattened metallic handle

Advantages of using farm tools for farm work
-   Minimize injury to the farmer
-   Make work easier/minimize drudgery
-   Enhance faster completion of operation/saves time
-   Enhance certain operations, e.g. budding
-   Not expensive to acquire
-   Easy to maintain
-   Increases farmers’ productivity
-   They are sometimes the only way to get certain operations done on the farm                    
-    Easy to operate and requires no high technical know-how
-   Do not require any specialised sources of power to operate
