This question was fairly attempted by the candidates. Most of the candidates were able to identify specimens Q (Scoop net), R (Fishing trap) and S(Drag net) but majority of the candidates could not draw and label specimen R (Fishing trap) as required in 4(a) and (b) respectively. However, majority of the candidates were able to state the materials used in making specimens Q (Scoop net), R (Fishing trap) and S (Drag net) as required in 4(c)(i). Finally, most of the candidates were unable to state the disadvantages of using specimens
Q (Scoop net), R (Fishing trap) and S (Drag net) as required in 4(c)(ii).
The expected answers include:
- Drawing and labeling of Specimen R (Fishing trap)
4(c)(ii) Disadvantages of using each of Specimens Q (Scoop net), R (Fishing trap)
and S(Drag net)
Specimen Q (Scoop net)
- It cannot catch/take large number of fish at at time
Specimen R (Fishing trap)
- The trigger may fail.
- Materials used in constructing it are not durable.
- Cannot catch large quantity of fish at a time.
Specimen S (Drag net)
