TEST OF PRACTICAL KNOWLEDGE QUESTION

(a)(i) Mention the field operation that could be performed Using specimens G, H, I and J

(ii) Name three other pieces of equipment that may be added to specimens G, H, l, and J to perform the operation you have mentioned in (a)(i).

(iii) State one precaution that should be taken when using specimen J.

(b). State two uses of each specimen K and L.

Specimen K;	Specimen L;
%%

(ii) State two structural differences between specimens K and L.

(iii) Mention two problems that could result from leaving specimen L on the field after use.

Answer

(a)(i) Field operation performed using specimens G, H, I and J

Farm surveying.

(a)(ii) Three other pieces of equipment that may be added

Levelling staff.
Dumpy level (or Abney level / theodolite).
Prismatic compass (or Gunter's / metric chain, or offset staff).

(a)(iii) One precaution when using specimen J (garden line)

Do not pull it too hard when taking measurements, so that it does not snap; and tie it firmly to the pole so it stays straight and horizontal for accurate readings.

(b)(i) Two uses of each specimen

Specimen	Two uses
K (hand trowel)	(1) Transplanting of seedlings; (2) Loosening of soil and light weeding.
L (mattock)	(1) Digging of soil and breaking hard pans; (2) Uprooting stumps and clearing bush during land preparation.

(b)(ii) Two structural differences between K and L

Feature	Specimen K (hand trowel)	Specimen L (mattock)
Blade	Boat-shaped blade, pointed at one end	Thick block of iron; one end long and pointed, the other broad, flat and sharp
Handle / size	Short cylindrical wooden handle, total length about 30 cm	Long cylindrical wooden handle, total length about 100 cm

(b)(iii) Two problems from leaving specimen L (mattock) on the field after use

The metal blade rusts on contact with rain and dew, blunting it and shortening its life.
It becomes a hazard: it may injure farm workers, be run over and damaged by farm machinery, be attacked (its wooden handle) by termites, or be stolen.
