Question 2
(a) Give three differences and three similarities in the use of specimens E and F. [ 6 marks ]
(b) (i) List two components of specimen E. [ 2 marks ] (ii) List four components of specimen F. [ 4 marks ]
(c) State three ways of maintaining specimen F. [ 3 marks ]
Observation
This question was poorly attempted by the candidates. In 2(a), most of the candidates could not give the differences and similarities in the use of specimens E (Hook and line) and F (Cast net). More so, most of the candidates could not list the components of specimens E (Hook and line) and F (Cast net) as required in 2(b)(i-ii). However, most of the candidates were able to state the ways of maintaining specimen F (Cast net) as required in 2(c).
The expected answers were:
2(a) Differences in the use of specimen E (Hook and line) and specimen F (Cast
net)
E (Hook and line) |
F (Cast net) |
Less energy required to operate |
More energy required to operate |
Catches one/ few fish at a time |
Catches many fish at a time |
Gear is selective |
Gear is not selective |
Catches do not include dirt |
Catches may include dirt |
May require use of bait/attractant |
Does not require use of bait/ attractant |
Passive gear |
Active gear |
Catches fish from any part of water (surface, bottom) |
Catches fish from water surface |
Attached to a stick |
Wound round the hand |
Similarities between specimens E (Hook and line) and F ( Cast net)
- They are both used for fishing/as fishing gear/for capturing fish.
- Both could be operated by one person.
- Twine is a major component of both.
- Both could have weight.
- Both can catch fish at water surface
(b) (i) Components of specimen E (Hook and Line)
- Hook
- Line / twine/rope
- Float
- Sinker/lead/weight/stone
(ii) Components of specimen F (Cast net)
- Wall of netting.
- Foot rope / lead line.
- Sinkers / lead / weight/stone.
- Holding rope/hand rope.
- Bag.
