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
