Introduction
6 minIntroduce today's words:
- inquiry question: A focused question that guides a geographical investigation.
- hypothesis: A testable prediction about a geographical pattern or relationship.
- primary data: Data collected first-hand, for example through fieldwork, surveys or measurements.
- secondary data: Data collected by others, such as census data, maps and reports.
- sampling: Selecting a subset of locations or people to represent a larger population.
- validity: Whether a method actually measures what it is intended to measure.
Ask your child what they already know about the geographical inquiry process.
Explanation
12 minGeographical inquiry generally moves through stages: acquiring (asking questions and planning), collecting and recording data, processing and analysing, communicating findings and reflecting and responding.
A good inquiry question is specific, researchable and geographical, meaning it is about place, space, environment, interconnection, scale, sustainability or change. 'How does pedestrian traffic vary with distance from the train station in [suburb]?' is stronger than 'What is my suburb like?'
A hypothesis turns a question into a testable statement, such as 'Pedestrian counts decrease with distance from the station.'
Primary data might include pedestrian counts, land-use mapping, environmental quality surveys, photographs, interviews and questionnaires. Secondary data includes census data, satellite images, climate records and government reports.
Sampling must be planned. Random, systematic and stratified sampling each have strengths. Small or biased samples weaken conclusions.
Analysis looks for patterns, trends and anomalies using maps, graphs and simple statistics. Conclusions should answer the question, refer to evidence and acknowledge limitations. Ethical fieldwork respects privacy, safety, property and the cultural protocols of First Nations communities whose Country is being studied.
Worked examples
9 minImproving an inquiry question
Improve: 'Is the beach eroding?'
Step 1: Make it specific in place and time: name the beach and period.
Step 2: Make it measurable: refer to beach width or dune position.
Step 3: Make it explanatory: include a possible cause.
Answer: 'How has the beach width at [beach] changed between 2015 and 2025, and what role have storm events played?'
Choosing a sampling method
You want to measure litter along a 1 km creek. How could you sample systematically?
Step 1: Divide the creek into equal intervals, e.g. every 100 m.
Step 2: At each point, survey a 10 m × 2 m quadrat along the bank.
Step 3: This gives 10 or 11 evenly spaced sample sites.
Answer: Systematic sampling at regular 100 m intervals using fixed-size quadrats.
Guided practice (do together)
12 min1. Which is an example of primary data?
(a) Census statistics (b) A pedestrian count you conducted (c) A government report (d) A published map
2. Which is the strongest inquiry question?
(a) What is my town like? (b) Do people like parks? (c) Why is geography good? (d) How does land use change with distance from the CBD of [city]?
3. What is a hypothesis?
(a) A testable prediction (b) A final conclusion (c) A type of map (d) A sampling site
4. Sampling at regular intervals along a line is called…
(a) random sampling (b) stratified sampling (c) systematic sampling (d) opportunistic sampling
Independent practice
15 min5. Why should conclusions acknowledge limitations?
(a) To show the reliability and scope of the findings honestly (b) To make the report longer (c) Because data is always wrong (d) To avoid answering the question
6. Data collected by others, such as census data, is called ____ data.
7. Selecting a subset of sites or people to represent a population is called ____.
8. Pedestrian counts at 5 sites were 40, 35, 30, 20 and 15. What is the mean?
Questions to check understanding
- Can you write a focused, researchable inquiry question?
- Can you choose appropriate primary and secondary data sources?
- Can you identify limitations in my data and methods?
- Can you draw conclusions supported by evidence?
- What was the trickiest part today?
Answer guide
1. A pedestrian count you conducted — Primary data is collected first-hand.
2. How does land use change with distance from the CBD of [city]? — It is specific, measurable and geographical.
3. A testable prediction — A hypothesis is tested by evidence.
4. systematic sampling — Systematic sampling uses regular intervals.
5. To show the reliability and scope of the findings honestly — Acknowledging limitations is part of rigorous inquiry.
6. secondary — Secondary data is collected by others.
7. sampling — Sampling makes data collection manageable.
8. 28 — (40 + 35 + 30 + 20 + 15) ÷ 5 = 140 ÷ 5 = 28.
Review
6 minRecap the success criteria together. Watch for these common misconceptions:
- More data is not always better data; well-planned sampling matters more than volume.
- Correlation is not causation; a pattern between two variables does not prove one causes the other.
Extension activities
- Conduct a mini-inquiry on a local issue such as traffic, litter or green space and write a 1,000-word report.
- Compare your primary data with census data for the same area.
- Present your findings as an annotated map.
Suggested follow-up
- Revisit the geographical inquiry process tomorrow with two or three quick questions from memory.
- Try the online practice check for this topic and look at any questions that need another go.
Tips for parents
- Check your state or territory course for required fieldwork and report formats.
- Supervise fieldwork for safety, and avoid collecting personal information from members of the public without appropriate consent.
- If fieldwork takes place on land with cultural significance, contact the local land council or Traditional Owner organisation about appropriate protocols.
