Skills of scientific inquiry, fieldwork and the assignment: overview for SQA National 5 Environmental Science
An overview of the skills of scientific inquiry, fieldwork and the assignment in SQA National 5 Environmental Science, covering sampling and fieldwork techniques, variables and data handling, evaluation, and the structure and marking of the assignment, with links to each page.

The skills of scientific inquiry, fieldwork and the assignment run through the whole of SQA National 5 Environmental Science. The course is examined not only on what you know but on how you investigate: how you sample, handle variables, process data, draw conclusions and evaluate a method. These skills are tested in the question paper and assessed directly in the assignment. This page maps the two pages in this area.
The two key areas
Fieldwork and inquiry skills. Sampling techniques such as quadrats and transects, measuring abiotic factors, identifying variables and controls, presenting and processing data, drawing valid conclusions, and evaluating reliability and validity.
The assignment. The externally marked report on a candidate-chosen investigation: what it is, the controlled conditions, the sections from aim to evaluation, the use of first-hand and research data, and how it rewards the inquiry skills.
How to build these skills
- Practise sampling calculations. Quadrat estimates (mean per quadrat, then scale up) and processing such as means and percentages come up often.
- Get the variables right. Always state the independent, dependent and controlled variables and explain the fair test.
- Separate reliability from validity. Reliability is about repeatability (repeat and average); validity is about a fair test measuring the right thing.
- Use the assignment mark scheme as a checklist. Aim, raw data, processing, presentation, analysis, conclusion and evaluation each earn marks by doing their job.
