Secondary 4 Geography Quiz - Fieldwork: Answer Key
Total Marks: 40
Duration: 45 minutes
Section A: Fieldwork Planning and Research Design
1. [1 mark]
Answer: To provide a testable statement that guides data collection and analysis.
Teaching note: A hypothesis predicts a relationship (e.g., "more litter near entrance"). It keeps the study focused and lets the student check if data supports it.
Common mistake: Saying "to get good results" – too vague; must show direction or relationship.
2. [2 marks]
Answer: The number of litter items decreases with increasing distance from the park entrance. (1 mark for variable relationship, 1 mark for clear direction)
Teaching note: Hypothesis must name both variables (distance, litter count) and propose a trend.
Marking: 1 mark for identifying variables, 1 mark for stating expected pattern.
3. [2 marks]
Answer: A narrow question is manageable within time/space limits (1); it allows clear data collection and specific analysis (1).
Teaching note: Broad questions like "study the environment" are hard to measure; narrow ones give actionable steps.
4. [2 marks]
Answer: Any two from: NEA temperature records, SingStat data, URA master plan, school records, online maps. (1 mark each)
Teaching note: Secondary data = already collected by others; useful for context before field visit.
5. [1 mark]
Answer: Stratified sampling covers different subgroups fairly, reducing bias.
Teaching note: Convenience may miss important zones; stratified ensures representation.
Section B: Data Collection Methods
6. [2 marks]
Answer: To gather people's opinions, behaviours, or knowledge (1) through set questions (1).
Teaching note: Used for human geography topics like sense of place or transport.
7. [2 marks]
Answer: A mental map shows a person's perception of an area (1) with landmarks, routes, and importance they draw (1).
Teaching note: Different from real map; reveals emotional/spatial connection.
8. [2 marks]
Answer: Any two: stand safely away from traffic, count in fixed time intervals, avoid distracting drivers, record systematically. (1 mark each)
Teaching note: Safety and consistency protect data quality.
9. [2 marks]
Answer: Field sketch can highlight key features and omit distractions (1); allows annotation of processes not visible in photo (1).
Teaching note: Photo shows real state but sketch shows understanding.
10. [2 marks]
Answer: Place quadrat on ground (1); count items inside frame and record on tally (1).
Teaching note: From figure, 1 m² frame used for standard area count.
Expected visual: Quadrat labelled 1 m², tally sheet present.
Section C: Sampling and Data Analysis
11. [2 marks]
Working: (4+7+5+8+6) ÷ 5 = 30 ÷ 5 = 6
Answer: Mean = 6 items. (1 mark for sum, 1 mark for division/correct answer)
Teaching note: Mean = average; add all, divide by count.
12. [2 marks]
Working: (8 ÷ 20) × 100 = 40%
Answer: 40% walk. (1 mark for fraction, 1 mark for % calculation)
Teaching note: Percentage = part/total × 100.
13. [3 marks]
Answer: Bar graph with Zone A=12, B=18, C=10. (1 mark axes/labels, 1 mark correct bars, 1 mark title/legend)
Teaching note: Use equal width bars, label values.
14. [2 marks]
Answer: Count how often each response occurs (1); look for highest/lowest or repeating values to see trend (1).
Teaching note: Frequency shows common patterns.
15. [1 mark]
Answer: More shade attracts more park users.
Teaching note: Positive relationship = both increase together.
Section D: Presentation and Evaluation
16. [2 marks]
Answer: Poster, oral presentation, graph display, video. (1 mark each, any two)
Teaching note: Reports not only written; varied audience reach.
17. [2 marks]
Answer: Temperature rises from 28°C at 8am to 33°C at 2pm then falls to 30°C at 5pm (1); highest at afternoon (1).
Teaching note: From graph values open field: 28,31,33,30.
Expected visual: 3 lines, open field peak at 2pm.
18. [2 marks]
Answer: Shows where data collected (1); helps reader understand spatial context (1).
Teaching note: Map links findings to place.
19. [2 marks]
Answer: Only one time may miss daily variation (1); weather that day may not be typical (1).
Teaching note: Single sample limits reliability.
20. [2 marks]
Answer: Collect data across multiple days/times (1); use more sites for comparison (1).
Teaching note: Repeated sampling improves confidence.
