End of Quiz
Answers
Secondary 1 Geography Quiz - Fieldwork (Answer Key)
Total Marks: 40
Section A: Multiple Choice Questions (10 marks)
1. B — Formulating guiding questions
Reasoning: The geographical inquiry process begins with identifying a question or problem to investigate. This guides the entire investigation. Data collection, analysis, and conclusions come later.
2. A — Areas with more vegetation cover have lower surface temperatures.
Reasoning: A hypothesis is a testable statement predicting the relationship between variables. Option A predicts a relationship between vegetation cover (independent variable) and surface temperature (dependent variable). Options B, C, and D are observations or general statements, not testable predictions.
3. B — Measuring wind speed using an anemometer at the study site
Reasoning: Primary data is collected first-hand by the researcher at the field site. Options A, C, and D are secondary data (collected by others).
4. B — Quantitative data collection
Reasoning: Quantitative data involves numerical measurements. Timing water infiltration with a stopwatch produces numerical data (seconds). Qualitative data would be descriptive (e.g., "water absorbs quickly").
5. A — Systematic sampling
Reasoning: Systematic sampling involves selecting samples at regular intervals (every 20m along a transect). Random sampling would use random coordinates; stratified sampling divides the area into zones first; opportunistic sampling selects convenient sites.
6. B — Wind vane
Reasoning: A wind vane (weather vane) shows wind direction. An anemometer measures wind speed; a thermometer measures temperature; a rain gauge measures rainfall.
7. C — Categorical (qualitative) data
Reasoning: Land use types (Residential, Commercial, etc.) are categories, not numerical values. This is qualitative/categorical data.
8. A — To ensure the equipment is working and the method is feasible
Reasoning: A pilot test is a small-scale trial to check equipment, methods, and timing before the main data collection. It identifies problems early.
9. B — Respondents may give socially desirable answers rather than honest ones
Reasoning: This is a known limitation of questionnaires (response bias). People may answer what they think is "right" rather than their true opinion. Options A, C, and D are advantages, not limitations.
10. C — Data analysis
Reasoning: Calculating descriptive statistics (mean, median, mode) to summarise and find patterns in collected data is part of data analysis. Data presentation would be creating graphs/tables; evaluation assesses the investigation's validity.
Section B: Structured Questions (18 marks)
11.
(a) Hypothesis: "Surface temperature is higher on concrete surfaces than on grass surfaces." / "The type of ground surface affects surface temperature, with artificial surfaces being hotter than natural surfaces."
[1 mark for a clear, testable statement predicting a relationship between ground surface type and temperature]
(b) Control variables (any two):
- Time of day measurements are taken (e.g., all at 1pm)
- Weather conditions (e.g., clear sky, no rain)
- Duration of exposure to sun before measurement
- Height of thermometer above ground surface
- Type of thermometer/instrument used
[1 mark each, max 2 marks. Must be variables that could affect temperature and need to be kept constant for a fair test]
(c) Equipment:
- Surface temperature: Infrared thermometer / Digital thermometer with surface probe / Thermometer gun
- Ground surface type: Observation / Camera (for recording) / Quadrant with identification key / Simply "eyes" or "visual observation"
[1 mark each. Accept any appropriate equipment for measuring surface temperature and identifying surface type]
12.
(a) Number of sampling points: 11
Working: 200m ÷ 20m = 10 intervals → 10 + 1 = 11 points (including start point at 0m)
[1 mark for correct answer with working shown]
(b) Advantage: Ensures even coverage across the entire transect / Quick and easy to set up / Avoids clustering of sample points
Disadvantage: May miss important variations between intervals / Could coincide with a periodic pattern (e.g., regularly spaced trees) / Less representative if the environment changes abruptly
[1 mark each. Must be specific to this investigation context]
13.
(a) Mean calculation:
Sum = 31.2 + 30.8 + 31.5 + 30.9 + 31.6 = 156.0
Mean = 156.0 ÷ 5 = 31.2°C
[1 mark for correct sum, 1 mark for correct mean with unit]
(b) Conclusion: "Concrete surfaces have a higher mean surface temperature (38.4°C) than grass surfaces (31.2°C), so ground surface type affects temperature." / "Artificial surfaces like concrete absorb and retain more heat than natural surfaces like grass."
[1 mark for a conclusion that uses the comparative means to answer the research question]
14.
(a) Essential elements (any two):
- Title describing what the graph shows (e.g., "Mean Surface Temperature of Different Ground Surfaces")
- Labelled axes with units (X-axis: Ground surface type; Y-axis: Mean surface temperature / °C)
- Appropriate scale on Y-axis
- Bars of equal width with gaps between them (since data is categorical)
- Accurate plotting of mean values
[1 mark each, max 2 marks]
(b) Reason: A bar graph is used for categorical/discrete data (different ground surface types), while a line graph is used for continuous data (e.g., temperature change over time). Ground surface type is not continuous.
[1 mark for distinguishing categorical vs continuous data]
15.
(a) Strength: The conclusion is supported by the data collected (mean temperatures show grass is cooler than concrete) / It directly answers the research question.
[1 mark]
(b) Limitations (any two):
- Small sample size (only 5 sites per surface) — may not be representative of the whole school
- Only one time of day measured — temperatures change throughout the day; conclusion may not hold at other times
- Correlation ≠ causation — other factors (shade, moisture, wind) may influence temperature, not just surface type
- Practicality not considered — replacing all concrete with grass may not be feasible (maintenance, drainage, usage)
- Generalisation — results from one school may not apply to other locations
[1 mark each, max 2 marks. Must be valid limitations of the conclusion/investigation]
16.
(a) Improve reliability: Take more readings at each site (repeat measurements) and calculate an average / Increase the number of sampling sites / Measure at the same time on multiple days and average the results / Use calibrated instruments
[1 mark for any valid method to increase reliability — consistency of results]
(b) Extend investigation (any one):
- Investigate at different times of day (morning, afternoon, evening)
- Investigate different seasons / weather conditions
- Measure air temperature at different heights above the surface
- Compare with other schools / urban vs rural areas
- Investigate the effect of surface colour / material composition
- Measure humidity / wind speed alongside temperature
[1 mark for a valid extension that adds depth or breadth]
Section C: Data Response and Application (12 marks)
17.
(a) Mean for Site B:
Sum = 180 + 195 + 185 = 560
Mean = 560 ÷ 3 = 186.7 seconds (or 186.67 s)
[1 mark for correct sum, 1 mark for correct mean with unit]
(b) Fastest infiltration rate: Site A (Grassy area)
Explanation: Site A has the lowest mean infiltration time (45 seconds) compared to Site B (186.7 s) and Site C (90 s). Since infiltration rate is inversely related to time (shorter time = faster rate), Site A has the fastest rate.
[1 mark for correct site, 1 mark for explanation using data]
(c) Reason for Site B's slow infiltration: The compacted path has compressed soil particles with reduced pore spaces, preventing water from entering easily. / Human foot traffic compacts the soil, reducing porosity and permeability.
[1 mark for linking compaction to reduced pore space/permeability]
18.
(a) Difference: 31.2°C – 27.5°C = 3.7°C
[1 mark for correct calculation with unit]
(b) Explanation: Site B (compacted path) has less vegetation cover than Site A (grassy area). Bare/compacted surfaces absorb more solar radiation during the day and have lower albedo (darker surface) and no evapotranspiration cooling effect from plants. The grass at Site A provides shade and cools the soil through evapotranspiration.
[1 mark for identifying lack of vegetation/shade, 1 mark for explaining mechanism (albedo, evapotranspiration, heat absorption)]
19.
(a) Potential error (any one):
- Water leaking from the sides/bottom of the infiltration ring (not sealed properly)
- Inconsistent initial soil moisture content between trials/sites
- Splashing or spillage when pouring water
- Not keeping the water level constant (falling head vs constant head)
- Timer started/stopped inconsistently
[1 mark for a valid, specific error in the method]
(b) Improvement (matching the error):
- Hammer the ring deeper / use sealant (e.g., bentonite) to prevent leakage
- Pre-wet the soil to a standard moisture content before timing / wait for same antecedent conditions
- Pour water gently using a splash plate / measuring jug with spout
- Use a constant-head infiltrometer (Mariotte bottle) / maintain constant water depth
- Use the same person for timing / digital timer with lap function
[1 mark for a practical improvement addressing the stated error]
20.
(a) Advantage of bar chart: Allows easy visual comparison of discrete categories (three sites) / Clearly shows differences in magnitude / Appropriate for categorical independent variable (site type)
[1 mark]
(b) Infiltration rate calculation for Site A:
Given:
- Volume of water = 500 ml = 500 cm³
- Ring diameter = 15 cm → Radius (r) = 7.5 cm
- Mean time = 45 seconds = 45/60 = 0.75 minutes
Step 1: Calculate cross-sectional area of ring
Area = πr² = π × (7.5)² = π × 56.25 = 176.71 cm² (using π ≈ 3.1416)
Step 2: Calculate height of water (h) in cm
Volume = Area × h → h = Volume / Area = 500 / 176.71 = 2.83 cm
Step 3: Convert height to mm
2.83 cm = 28.3 mm
Step 4: Calculate infiltration rate (mm/min)
Rate = Height (mm) / Time (min) = 28.3 / 0.75 = 37.7 mm/min
Alternative working using formula directly:
Rate (mm/min) = (Volume in mm³) / (Area in mm² × Time in min)
= (500,000 mm³) / (17671 mm² × 0.75 min) = 500,000 / 13,253 = 37.7 mm/min
Answer: 37.7 mm/min (accept 37.7 – 37.8 depending on π value used)
[1 mark for correct area calculation, 1 mark for correct height/volume conversion, 1 mark for correct final rate with units]
Marking Notes for Teachers:
- Award marks for correct working even if final answer has arithmetic error (error carried forward).
- For Q20(b), accept use of π = 3.14 (gives 37.74 mm/min) or π = 22/7 (gives 37.71 mm/min).
- In Section C, credit geographical understanding even if terminology differs (e.g., "porosity" for "pore spaces").
- For evaluation questions (Q15, Q16, Q19), accept any reasonable, context-appropriate answers.
