A good small investigation asks one measurable question, samples fairly, records safely, and reports honestly. This area teaches each of those four parts with worked examples.
Real fieldwork is arranged through your school and teacher. The lessons here train the design and reporting skills, and they help you analyse data when a question gives you a fieldwork table. They connect to the wider Geography learning guide.
How do the four parts connect?
- Turning a broad topic into an answerable local investigation question: one question you can measure.
- Choosing a sampling method and explaining its limitation: fair points, and what they miss.
- Recording observations without collecting identifiable student or household data: safe recording sheets.
- Presenting limitations and student-authored findings without fabricating fieldwork: an honest write-up.
Each part feeds the next, so the order matters. Then test the set in the investigation design practice questions.
Example: narrowing a broad topic
This is a worked example. The topic “litter” is too broad to measure. A narrower question is: “Does the number of litter items per 10 m differ between the food court strip and the garden strip of one promenade?”
That question names what to count, the unit, and the two places to compare. From it, the sample (points in each strip), the recording sheet (tallies, no names) and the limits (one day, few points) all follow. The broad topic gave none of those.
Who should start where?
If you are not sure what to investigate, begin with the question lesson. If you have a question and need to justify your points, begin with sampling, and first read choosing a sampling approach for the three common approaches.
If you worry about writing up results you did not collect, read preparing a geographical investigation without fabricated fieldwork.
