26.1 Structure of a scientific research paper
Learning objective: Organize a paper around a question and an evidence-based answer rather than a chronological account of laboratory activity.
Give each section a purpose
A typical research paper includes a title, abstract, introduction, methods, results, discussion, conclusions, references and statements about data, contributions or interests. Journals differ, so check the current instructions for the intended publication. The scientific functions matter more than memorizing one fixed arrangement.
The introduction explains the problem and why the study is needed. Methods explain how evidence was obtained and analysed. Results present observations and calculated outcomes. Discussion evaluates what those results mean, how they compare with previous work and which explanations remain possible. The conclusion answers the research question within the study’s scope.
Maintain a visible chain of evidence
Use a working outline that links each main claim to a figure, table or result. If a claim has no supporting observation, either obtain the necessary evidence or qualify the statement. Do not place a new, essential result only in the conclusion. A reader should not have to guess which specimen or method supports a sentence.
For a hypothetical study comparing two published meteorite datasets, the methods must explain inclusion criteria and any unit conversion. The results should show the comparison. The discussion should consider whether different analytical methods or sample histories limit the interpretation. Simply arranging quotations from earlier papers does not create a new empirical investigation.
Use clear and accurate labels
Keep specimen identifiers, units and terminology consistent from abstract to supplementary files. Explain abbreviations at first use. A preliminary identification report should not imitate an accredited laboratory certificate unless the stated status is real. Add an explicit description of the work’s scope. The COPE publication-ethics framework provides context for responsible reporting and editorial oversight; the target journal’s current policy remains the operational reference.
Practice and review
Key terms: Results—reported observations and calculations; discussion—interpretation and evaluation; supplementary material—supporting files linked to the paper.
Activity or question: Where should an untested explanation of a dark vein be placed?
Answer and explanation: In the discussion as a qualified interpretation, connected to the observed results and alternative explanations. Do not present the interpretation as a measured fact.
Question and rationale
Materials and methods
Observed results
Interpretation and alternatives
Supported conclusion and accessible record
26.2 Writing abstracts and introductions
Learning objective: Summarize the actual study and introduce its question without overstating novelty or certainty.
Write the abstract after the evidence is stable
An abstract should identify the question, material or dataset, principal method, main result and its significance. Include important limitations when they affect the conclusion. Report an actual result rather than saying only that the paper “discusses meteorites.” Do not add numbers to the abstract that are absent from the documented analysis.
If the work uses published photographs, say so. If the result is preliminary or based on a small sample, make that status clear. A concise abstract can remain readable while distinguishing an image-based observation from a laboratory measurement. The word “confirmed” should appear only when the evidence and scope support it.
Build the introduction around the gap
Begin with enough background for the intended reader, then narrow to the unresolved issue. Define technical terms when they become necessary. Explain why existing studies do not already answer the particular question. Cite the original sources for key claims rather than relying on an unsourced general statement.
Avoid claiming that no one has ever studied a subject merely because your first search found little. Describe the search and the specific limitation in available evidence. A focused contribution may be a better comparison, clearer uncertainty evaluation or a documented negative result; it need not be advertised as a revolution.
Check alignment
Compare the title, final paragraph of the introduction and conclusion. They should address the same scientific question. If the project changed during analysis, revise the writing to reflect the final work and identify exploratory findings appropriately. Do not preserve an ambitious original title after the evidence supports only a narrower result.
For practice, write a five-sentence abstract for an explicitly hypothetical reference-image study. Then underline the question, method, result and limit. Replace vague phrases with the actual material and observation. Keep fictitious results clearly marked as teaching examples.
Practice and review
Key terms: Abstract—stand-alone summary; research gap—specific unresolved issue; novelty—new contribution relative to earlier work.
Activity or question: An image study finds rounded features but no mineral chemistry. Can its abstract announce a newly classified ordinary chondrite?
Answer and explanation: No. It can report the image observations and their implications, but formal classification requires suitable evidence beyond those images.

26.3 Materials, methods and analytical results
Learning objective: Provide enough information to understand what was examined, how measurements were obtained and how results were derived.
Identify the material
State specimen identifiers, provenance relevant to the study, preparation and the relationship between subsamples. Explain whether the material is a physical specimen, a published dataset or a simulation. A named meteorite’s known classification does not automatically authenticate an untraceable fragment supplied under that name.
Describe sampling locations and selection criteria. If a polished section includes several lithologies, identify which were analysed. Preserve records of material consumption and treatments that could influence chemistry or magnetic properties. Methods should explain what actually happened, including justified deviations from the planned procedure.
Describe the measurement chain
Provide instrument and method information needed to assess the result: relevant operating conditions, calibration approach, reference materials, blanks, correction methods and uncertainty evaluation. A brand name alone does not define an analytical method. Separate quantitative results from qualitative screening.
For reused data, cite the source and document extraction, filtering, conversion and recalculation. For software, record the version and important settings or code. NASA’s data and software policy FAQ illustrates why accessible analysis instructions matter for covered research. Apply the actual requirements of the funder and journal rather than assuming one policy governs every project.
Present results without hiding limitations
Report units, uncertainty and the meaning of “not detected” or missing values. Show sample numbers and whether variation represents repeated readings, different grains or independent specimens. A rounded mean without its spread can conceal a heterogeneous sample.
Keep interpretation distinguishable from the measurement. “Nickel was detected in this analytical area” is different from “the object is a meteorite.” Explain mixed spots, poor preparation and failed quality checks rather than quietly excluding them. If a result cannot support the intended conclusion, preserve it with its limitation or justify exclusion in the methods.
Practice and review
Key terms: Method—documented procedure; analytical area—region contributing to a result; reporting limit—method-dependent threshold for reporting; subsample—portion linked to a parent specimen.
Activity or question: What is missing from “We used XRF and confirmed a meteorite”?
Answer and explanation: The specimen identity, sampling, calibration, quantitative capability, uncertainty, quality checks and reasoning are missing. XRF elemental information alone does not establish extraterrestrial origin.

26.4 Scientific figures, tables and photographs
Learning objective: Create visuals that explain evidence accurately and remain understandable without relying on colour alone.
Give the figure a scientific job
Choose a figure because it answers a question: a map shows recovery context, a micrograph shows grain relationships, and a graph shows variation or a comparison. A table is useful when readers need exact repeated values. Avoid a decorative image that implies evidence the study never collected.
Label axes with quantity and unit, explain symbols and identify sample numbers. Use readable text at the expected display size. Show uncertainty where it is meaningful, and explain what bars or shaded regions represent. A logarithmic axis or truncated scale must be clearly identified because it changes how differences appear.
Preserve image integrity
Keep original image files and record processing. Global adjustments may improve visibility, but selective manipulation that removes features or exaggerates a boundary can mislead. Do not combine views without marking the joins and explaining the construction. A scale bar is valid only when tied to the image’s calibration.
Captions should identify the specimen, method, view, scale and the feature being discussed. Alt text should describe the important visual information for someone unable to see the image. A short title can identify the visual; it should not simply repeat a long alt text. Retain required image credits and licence links, and check whether modifications must be indicated.
Check the table and caption together
Use clear headings, consistent units and sensible significant figures. Distinguish measured values from calculated or hypothetical ones. Do not use blank cells ambiguously: explain whether they mean not measured, not detected or not applicable.
For practice, sketch a figure comparing three invented density measurements and label it “hypothetical teaching data.” Include individual points, units and a caption describing the assumptions. Ask a second reader what conclusion the visual appears to make. Revise it if the design suggests more certainty or broader representativeness than the data support.
Practice and review
Key terms: Scale bar—calibrated size reference; caption—explanation accompanying a visual; alt text—text conveying visual meaning; significant figures—digits justified by the measurement.
Activity or question: May an auction catalogue photograph be copied into a course simply because it is online?
Answer and explanation: No. Check the rights and permitted use. Linking to the source or making an original diagram can be preferable when reuse permission is not established.

26.5 Discussion, conclusions and references
Learning objective: Explain what follows from the results, compare alternatives and connect every important borrowed claim to its source.
Interpret without exceeding the evidence
Start the discussion with the result most relevant to the question. Explain which interpretation it supports and which alternatives remain. A resemblance to a known specimen may motivate a hypothesis, but it is weaker than a traceable mineralogical and chemical comparison. State where the inference depends on assumptions.
Compare with previous studies at the appropriate scale. A bulk analysis cannot always be compared directly with a single-grain result, and a weathered find may differ from a fresh fall for reasons unrelated to parent-body origin. Discuss method, sample history and uncertainty before proposing a new group or process.
Make limitations specific
Useful limitations explain their likely effect. “The study is limited” says little; “only one section was examined, so rare components elsewhere may have been missed” tells the reader what remains uncertain. Distinguish unresolved identity, limited representativeness and measurement uncertainty. They require different follow-up work.
A conclusion should answer the question in a few supported statements and identify important next steps. It should not introduce a stronger claim than the discussion or announce an exact parent asteroid without the necessary evidence. Negative or unresolved results can still clarify what methods cannot establish.
Build a reliable reference list
Check author, year, title, identifier and links against the actual source. Cite a scientific database record with its version or access date where appropriate. Do not invent a DOI or cite a paper you have not inspected as if it directly supports the claim. A secondary source may be cited honestly as such.
For a review exercise, highlight every factual sentence in a discussion and identify whether it rests on this study’s data, an external source or a clearly labelled hypothesis. If none applies, revise or remove the claim. References are part of the evidence trail rather than an ornament at the end.
Practice and review
Key terms: Inference—conclusion drawn from evidence; limitation—specific boundary on interpretation; representativeness—how well a sample reflects a broader set.
Activity or question: A result is compatible with two meteorite groups. What should the conclusion say?
Answer and explanation: State the compatible possibilities and the evidence needed to distinguish them. Do not select the more commercially attractive label without support.

26.6 Peer review and responsible scientific publication
Learning objective: Respond to criticism with evidence, understand the limits of review and keep the published record correct.
What review can do
Peer reviewers assess whether the question, methods, reasoning and reporting are appropriate for the journal. They may identify missing evidence, unclear sampling or an unsupported interpretation. Review is a quality-control process, but acceptance does not guarantee that every measurement or conclusion is correct. Readers and later studies still evaluate the work.
Choose a journal whose scope matches the project and inspect its current editorial policies, fees, data requirements and publication process. Do not equate a flattering invitation or rapid acceptance with scientific credibility. The joint principles of transparency and best practice in publishing provide a useful framework for evaluating journal information.
Prepare a reasoned response
Address each substantive comment. Explain changes, give locations in the revised manuscript and provide evidence when disagreeing. A reviewer can be mistaken, but disagreement should be scientific and respectful. Do not hide an unresolved analytical issue by changing only the wording of the abstract.
If new analyses are needed, consider whether they are feasible and justified before consuming more material. If they cannot be obtained, narrow the conclusion and state the limit. Keep the revised data and version history consistent so a reviewer can see which result supports the final claim.
Responsibilities after acceptance
Check proofs, figure labels, units and supplementary files. Preserve the link between the published article and the accessible data. If a serious error later appears, contact the responsible collaborators and journal, assess affected conclusions and follow the correction process. A correction is different from silently changing a web copy.
Disclose relevant commercial interests, including ownership of material whose value could be affected by a classification claim. Publication should not be used to disguise advertising as an independent scientific conclusion. Authorship and acknowledgements should accurately reflect contributions and the applicable journal policy.
Practice and review
Key terms: Peer review—expert assessment before or after publication; proof—prepublication formatted version; correction—documented amendment to the record; competing interest—interest relevant to impartial interpretation.
Activity or question: A reviewer requests a claim that your data do not support. Should you add it to obtain acceptance?
Answer and explanation: No. Explain the evidential limit and propose accurate wording or justified additional work. Scientific responsibility remains with the authors.
Sources and further study
These sources support the scientific and professional principles discussed above. Hypothetical teaching examples are identified as such; they are not reported measurements of an unnamed specimen.
