JC1 H2 Geography Promotional Exams 2023 Mark Scheme H2 Fieldwork SQ (40m) AO1-13m, AO2-17m, AO3-10m 1 A group of four Geography students from Singapore conducted fieldwork to investigate the extent to which residents of Treelodge@Punggol practice eco -friendly habits. Treelodge@Punggol is an eco-estate in Singapore designed to encourage eco-friendly practices among their residents. They developed the following hypothesis: “Majority of the residents in Treelodge@Punggol adopt eco-friendly practices.” They visited Treelodge@Punggol on a Friday afternoon during their June Holidays, from 12 noon- 2pm. As this was their first time there, they spent the first 15 minutes conducting a site reconnaissance in the estate to take photographs and recording aspects of Treelodge@Punggol that encouraged eco-friendly living. As Treelodge@Punggol provides free planter boxes for residents to grow herbs and plants in their balconies, they stood at the ground floor to count the number of balconies used by residents to grow plants. To do so, they spread themselves across 4 blocks t o count. However, there were some uncertainties about how many potted plants counted as greenery. Next, the students split up and conducted surveys alone to find out if residents adopted eco-friendly practices. The students used convenience sampling and surveyed 12 residents in total. However, during the survey, there were language barriers when some elderly could only converse in dialect. Resource 1 shows the photographs taken by students showing eco -friendly features and messages in Treelodge@Punggol. Resource 2 shows the data collected by students on the balconies with and without greenery. Resource 3 shows their data recording sheet for the surveys. Resource 4 shows the survey findings. a) Explain one strength and one weakness in the students’ hypothesis. [4] AO1 Award 1m for each relevant point. Award 1 additional mark for further development of each explanation. Strength: • It is of a suitable scale as the investigation is conducted in one location, Treelodge@Punggol. [1 mark] This is manageable for 4 students to complete the investigation within the time given. [1 additional mark] Weakness: • However, it is not feasible to investigate if majority of residents adopt eco- friendly practices as they would not be able to collect data on all the residents. [1 mark] This is because the students were only given 2 hours to complete their investigation, which is insufficient time. [1 additional mark]

b) Explain how the students could minimise potential risks during data collection. [4] AO1 Award 1m for each relevant point. Award 1 additional mark for further development of each explanation. • Stay well hydrated as the investigation is conducted at noon when the weather is hot. [1 mark] Students could also wear suitable clothing such as light- coloured & cool clothing, or a cap to protect themselves from the heat/sun. [1 ad
