JC2H2PE2018 PAPER 2 TEMASEK JUNIOR COLLEGE GEOGRAPHY DEPARTMENT 1 SECTION A Theme 4: Geographical Investigation 1 (a) Design a recording sheet that the students may use to collate their data collected across the different sites marked out in Resource 1. Award 1 mark for title, award 2 ma rk for accurate components in data recording sheet (including consideration of sites, pH and turbidity scores). [3] (b) With reference to Resources 1 and 2, explain the limitations pertaining to the planning and data collect ion of the investigat ion. Suggest how these limitations can be overcome. Indicative Content: • Uneven spacing of sites – to be overcome by ensuring even spacing of sites along Pang Sua River • Impacts of water quality not only limited to Pang Sua River – to be overcome by also looking at other potential sites where water quality may be affected by industries • Too limiting to conduct study on Saturday morning – other days and times to be considered • Timing of data collection at sites to also be reassessed • Method of data collection has issue of subjectivity – overcome by using more sophisticated equipment to take readings of pH and turbidity. Consider also other ways to measure water quality. • Getting more students involved to conduct study for greater effectiveness and more reliable data. [7] (c) Suggest how the students can mitigate the potential risks that may arise when undertaking this investigation. Indicative Content: • Road safety • Attire for fieldwork • Safety from falling into channel • Safety from chemicals in channel • Weather-related considerations [3] (d) Explain why the group’s data may differ if they had conducted their investigation after a heavy thunderstorm. Indicative Content: [4]

JC2H2PE2018 PAPER 2 TEMASEK JUNIOR COLLEGE GEOGRAPHY DEPARTMENT 2 • Increase in turbidity – addition of sediment from surrounding area picked up by overland flow • Decrease in turbidity – addition of rainfall into channel discharge • Neutralising pH value – addition of rainfall into channel discharge • Lowering pH value – effect of acid rain (e) Suggest how the group of students can extend their investigation to examine the impact of Sungei Ka dut Industrial Estate on local communities. Indicative Content: Candidates will need to consider what the other impacts may be that arise due to the activities in the industrial estate. A higher level response will highlight the various groups of people that may make up the local community in the area around the Sungei Kadut Industrial Estate, of which they may experience different forms of impacts due to the activities at the industrial estate. They may also consider the adaptions of the investigation in a lignment with the five stages of investigation, which include: • Crafting the research question or hypothesis • Developing a plan for the new investigation • How to go about collectin
