What are the stages of a geographical enquiry, and how do you plan a fieldwork investigation?
The stages of the geographical enquiry process and how to plan a fieldwork investigation with a clear aim and hypothesis (AO3).
A focused CCEA GCSE Geography guide to the geographical enquiry process for Unit 3 fieldwork. Covers the stages of an enquiry, how to choose a suitable aim and hypothesis, how to link fieldwork to a Unit 1 or Unit 2 topic, and what the Unit 3 exam expects.

What this dot point is asking
CCEA's Unit 3 Fieldwork is a one-hour written exam, not coursework, in which you answer questions on a fieldwork investigation you have carried out, based on a topic from Unit 1 or Unit 2. This dot point covers the first stage: understanding the geographical enquiry process and how to plan an investigation with a clear aim and a testable hypothesis. You take an approved fieldwork statement and a table of your data into the exam, so you revise your own study.
The geographical enquiry process
Linking fieldwork to a topic
Your investigation must be based on a topic from Unit 1 or Unit 2. Common choices include:
- River Environments - how bed load size, river width or velocity change downstream.
- Coastal Environments - how beach material or beach profile changes along a coast.
- Changing Urban Areas - how land use, environmental quality or pedestrian counts vary across a town.
Choosing a topic you understand makes the analysis and conclusion far easier, because you can explain the processes behind your results.
Writing the aim and hypothesis
Why careful planning matters
Planning before fieldwork is itself examined.
- A clear aim and hypothesis keep the study focused, so you collect only the data you need.
- Choosing suitable sites, methods and sampling in advance makes the data reliable and fair.
- A risk assessment keeps the group safe (for example checking river depth or tide times).
- Checking equipment ensures the measurements can actually be taken.
Worked example: planning a river study
Common mistakes
Examples in context
Example 1. Why a sharp hypothesis makes the whole study easier. If your hypothesis is precise, such as "bed load becomes smaller downstream", then every later stage has a clear purpose: you know what to measure, how to present it (a graph of size against distance), and how to conclude (does the graph support the prediction?). A vague hypothesis leaves you with data you cannot interpret, which is why examiners reward a tight, testable statement from the start.
Example 2. The fieldwork statement you take into the exam. Because Unit 3 is examined on your own investigation, you bring an approved fieldwork statement and a table of your data. This means revision is about knowing your aim, methods, sites and results inside out, not memorising a textbook example. Understanding the enquiry process lets you answer questions about any stage of the study you actually did.
Try this
Q1. Is Unit 3 Fieldwork coursework or a written exam? [1 mark]
- Cue. A written exam (one hour), on your own fieldwork investigation.
Q2. What is the difference between an aim and a hypothesis? [2 marks]
- Cue. The aim states what you are investigating and where; the hypothesis is a precise, testable prediction the data can support or reject.
Q3. Give one reason careful planning matters before fieldwork. [1 mark]
- Cue. It keeps the study focused, makes the data reliable and fair, or keeps the group safe.
Exam-style practice questions
Practice questions written in the style of CCEA exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
CCEA Unit 3 (style)4 marksState a suitable aim and hypothesis for a fieldwork investigation linked to a topic you have studied.Show worked answer →
Four marks: two for a clear aim, two for a testable hypothesis.
Aim: to investigate how the size and roundness of bed load change downstream along a river, linked to the River Environments topic.
Hypothesis: bed load will become smaller and rounder with distance downstream from the source.
A good aim states clearly what is being investigated and where, and the hypothesis is a precise, testable statement that the data can support or reject.
Markers reward an aim that names the topic and location and a hypothesis that is specific and testable, not a vague question.
CCEA Unit 3 (style)6 marksExplain why it is important to plan a fieldwork investigation carefully before collecting data.Show worked answer →
Six marks for explained reasons that planning matters.
A clear aim and hypothesis keep the investigation focused, so you collect only the data you actually need to test the idea.
Choosing suitable sites and methods in advance, and a sensible sampling strategy, makes the data reliable and fair and avoids wasting time on site.
Planning for risk (a risk assessment) keeps the group safe, for example checking river depth or tide times, and checking equipment means measurements can actually be taken.
Good planning therefore produces valid, reliable results that can give a clear conclusion.
Markers reward reasons linked to focus, reliable and fair data, safety, and a usable conclusion.
