Secondary 1 Geography Quiz - Fieldwork (Answer Key)

Total Marks: 40
Topic: Fieldwork


Section A: Multiple Choice

  1. B (1 mark)
    Teaching note: Fieldwork means going out to a real place to observe and collect data yourself. It is not about memorising or copying from books. Choice B is correct because geographers use fieldwork to get first-hand information.

  2. C (1 mark)
    Teaching note: A primary source is data you collect directly. Water temperature measured at a river is first-hand data. Textbook maps and newspaper articles are secondary sources.

  3. B (1 mark)
    Teaching note: Grid references always read easting (horizontal, left-to-right) first, then northing (vertical, bottom-to-top). This is a common exam trap—do not reverse the order.

  4. B (1 mark)
    Teaching note: Air and water temperatures rise and fall during the day. Recording time helps others understand why a reading was high or low.

  5. B (1 mark)
    Teaching note: Turbidity measures how cloudy water is. Higher NTU means more suspended soil or particles, not clearer water.


Section B: Short Answer

  1. (Any one) A field sketch can highlight only important features; it is not distracted by extra background; it can show direction and labels clearly. (2 marks)
    Marking: 1 mark for valid advantage, 1 mark for brief explanation if needed.

  2. Any two: thermometer, turbidity tube, pH paper, measuring tape, notebook, camera. (2 marks: 1 mark each)
    Teaching note: These are common Sec 1 fieldwork tools for water study.

  3. To check accuracy / reduce error / because one reading may be a mistake. (2 marks: 1 for point, 1 for reason)
    Teaching note: Repeated readings let students find an average and spot odd results.

  4. To show the location of a place on a map using easting and northing numbers. (2 marks)
    Teaching note: 4-figure grid reference gives the grid square (e.g., 1222).

  5. Any one: Stay with a buddy; wear non-slip shoes; do not go into deep water; listen to teacher. (2 marks)


Section C: Data & Structured Response

  1. (a) 1222 (1 mark)
    (b) 1323 (1 mark)
    Teaching note: Read easting (12 / 13) first, then northing (22 / 23). Use lower-left corner of square.

  2. One difference e.g., Site Y has higher turbidity (15 NTU) than Site X (8 NTU); OR Site X has higher dissolved oxygen (6.2) than Site Y (4.8). (2 marks: 1 for correct value comparison, 1 for naming the variable)

  3. Site X has healthier water. (1 mark)
    Reasons: Lower turbidity (8 vs 15) means clearer water; higher dissolved oxygen (6.2 vs 4.8) supports fish and plants. (2 marks)
    Teaching note: Aquatic life needs oxygen and clear water with less suspended dirt.

  4. Site Y is near the Picnic Area (from map), so more soil or litter may wash in; OR less forest cover near Y. (2 marks: 1 for map link, 1 for reason)

  5. Width = 4.6 m − 0.0 m = 4.6 m (2 marks: 1 for subtraction, 1 for unit)
    Working: Right bank 4.6 m − left bank 0.0 m = 4.6 m.

  6. Difference = 27 − 12 = 15 items (2 marks: 1 for calculation, 1 for unit/answer)

  7. Any three: title, north arrow, scale, labels of features, simple drawings of landforms, date. (3 marks: 1 each)

  8. Most common: Bus (14 students). (2 marks: 1 for mode, 1 for number)
    Teaching note: Bar graph shows Bus bar tallest at 14.

  9. So others know when and where the photo was taken; helps in writing the report. (2 marks)

  10. Any two: field sketch of mangrove trees, count aerial roots, measure salinity, record species, take photos. (2 marks: 1 each)
