Answer Details
(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.
