Prelim 4E GY 2279/01 2025 2 1 Cluster 1: Geography in Everyday Life A group of students from Horizon High School is interested to find out residents’ perception of urban heat within a precinct. They want to investigate if the type of surface material influences the likelihood and frequency of residents spending time in various outdoor locations. They tested the hypothesis: ‘Residents prefer to visit outdoor locations with natural surfaces than artificial ones due to lower perceived heat.’ To prepare for their investigation, the students conducted a pilot survey on a Saturday afternoon. Fig. 1.1 shows an excerpt from their fieldwork journal that documents insights gained during the pilot survey. Excerpt from the students’ fieldwork journal Date: 5 May 2025 Time: 2:00 PM - 4:00 PM Location: Ang Mo Kio Block 400s (near a small community garden) Sample size: 10 residents Notes: - Managed to find respondents quite easily. Many residents were reluctant to stop for long interviews due to the heat. Administered a short closed-ended questionnaire and attempted mental mapping. Some participants found it hard to draw detailed maps from scratch. Q5 was interpreted differently by different respondents. Fig. 1.1 (a) (i) Suggest a measure that students could be implemented to mitigate a possible risk faced during their investigation. [2] Award 1m for identification of possible risk. Award 1m for suggesting a reasonable measure to mitigate it. • Risk: Heat stress / Dehydration / Sunburn [1] • Mitigation: Students should stay hydrated by drinking plenty of water/ wear light and loose clothing/ take frequent breaks in shaded areas/ schedule fieldwork during cooler periods of the day [1] Accept all plausible answers. AO1 (ii) Using Fig. 1.1, suggest why conducting a pilot survey is important. [2] Award 1 mark for suggesting a benefit of pilot survey, up to 1m. Award 1 additional mark for a further elaboration, up to 1m. • To identify potential problems/challenges with fieldwork methods to make changes/improve/refine [1]

After finding out that most respondents do not know how to draw maps from scratch, they can provide base maps for the actual investigation [1 additional mark] • To assess feasibility of the investigation [1] o Whether or not the selected time, duration and venue is easy to find respondents if the timeframe [1 additional mark] AO2 (b) The students decided to conduct a questionnaire to investigate their hypothesis near four different outdoor locations withi
