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]

OBSERVATION

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.

Tools that can perform similar functions as specimens H, I and J
-  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
• Has a long wooden/metallic handle
• 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
