To format a lab report, put the sections in this order — aim, hypothesis, method, results, analysis, conclusion, references — each under its own heading, then apply the house rules: a readable 12-point font, 1-inch margins, the spacing your sheet demands, page numbers after the title page, captions above tables and below figures, and units on every number. The puzzle below drills the order; the checklist turns the rest into twelve taps.
Honesty note: format rules vary by course. The order and the twelve checks here follow the most common school and undergraduate lab sheet; where your sheet disagrees — a discussion instead of an analysis, single spacing, the aim folded into an introduction — the sheet wins every time. This page also checks structure and presentation, not science: no checklist can tell you whether your hypothesis was right, only whether the report carrying it is tidy enough to be believed.
The section order puzzle
Graders read a lab report the way a conductor reads a score: the parts are familiar, so what registers first is whether they arrive in order. A report that opens with its results has spoiled its own story — the method has not happened yet, the hypothesis was never stated, and the conclusion has nothing left to settle. The standard sequence is not arbitrary. It is the shape of the work itself: decide what you are asking (aim, hypothesis), say how you went looking (method), show what turned up (results), say what it means (analysis), close the loop (conclusion), and credit your sources (references). A reader who knows the sequence can find any part of your work blind; a reader who does not know where anything lives starts marking structure instead of science.
The puzzle makes that sequence something your hands know, not just your notes. Seven rows are shuffled every round — aim, hypothesis, method, results, analysis, conclusion and references, each with a one-line reminder of the job it does. Move a row with the up and down buttons, press Check order, and every slot turns green or red: green means the section sits where the sheet expects it, red means it does not, so a red row two places from home is a two-move fix, not a rewrite. Your attempts are counted, your arrangement survives a closed tab, and Reset & reshuffle clears the saved board and deals a new one for another round.
Section order puzzle
100% private — runs in your browser- ResultsThe data: tables and figures with units, reported not argued.
- HypothesisA testable prediction with a reason — the data can prove it wrong.
- ReferencesEvery source the report cites, in the style the sheet demands.
- AimOne sentence: what the experiment set out to measure.
- ConclusionThe verdict on the hypothesis, in two or three sentences.
- MethodApparatus and procedure, past tense, detailed enough to repeat.
- AnalysisThe graphs worked and the pattern named — what the data show.
Your arrangement saves to this browser only — one storage key, csw-lrf-v1, updated the moment you move a row, so a closed tab does not lose the board. Reset erases that key and shuffles a fresh deal. Checklist taps, quiz answers and poll clicks are never stored.
Once the order is muscle memory, filling each slot is the next job. The lab report template gives all seven sections fill-in boxes with placeholder hints and live word counters, and the how to write a lab report guide plans the whole IMRaD draft before you type a word of it — the puzzle tells you where things go, and those two tell you what goes there.
The correct order, section by section
Each section of a lab report has exactly one job, and the order exists so that every job has what it needs before it starts. The aim needs no data. The hypothesis needs the aim. The method needs the hypothesis it was designed to test. The results need the method to make sense of them, the analysis needs the results to chew on, and the conclusion needs every section before it — which is why a conclusion that introduces a new number reads as a confession that something was missing earlier. The shares below are planning heuristics for a school lab of about 1,500 words, not a rubric; your sheet's word count outranks them.
| Slot | Section | Its one job | Typical share of a 1,500-word lab |
|---|---|---|---|
| 1 | Aim | One sentence: what the experiment set out to measure | ~5% |
| 2 | Hypothesis | A testable prediction with a reason behind it | ~5% |
| 3 | Method | Apparatus and procedure, past tense, repeatable by a stranger | ~25% |
| 4 | Results | The data — tables and figures with units, no arguments | ~25% |
| 5 | Analysis | The graphs worked and the pattern named | ~20% |
| 6 | Conclusion | The verdict on the hypothesis, two or three sentences | ~10% |
| 7 | References | Every cited source, in the required style | outside the count |
Two boundaries in that table do most of the marking work. The first sits between results and analysis: results report, analysis interprets, and a number that arrives with the phrase "which proves" has crossed the line in the wrong direction. The second sits inside the conclusion: it settles the hypothesis the report opened with, and it does not open new evidence — the section that words that verdict well is the lab report conclusion builder, and the section that sets the whole chain up is the lab report introduction, which turns a broad topic into the aim and hypothesis the order begins with.
The twelve-point format check
Structure is half the format; presentation is the other half, and it is where the cheap marks live. Run every finished draft through the twelve checks below the night before submission — each one is a ten-second fix on a screen and a lost mark on paper. The bar fills as you tap, honest taps only, and the full dozen earns a small celebration.
- Margins sit at 1 inch (2.54 cm) on all four sides of every page.
- The whole report uses one readable 12-point font — no face or size changes mid-page.
- Line spacing matches the sheet (double or 1.5) through the prose; tables and captions may single-space.
- Every page after the title page carries a page number, in one consistent corner.
- The title page lists title, name, partners, course, teacher and date.
- Sections run in the required order, each under its own heading.
- Tables are numbered and captioned above (Table 1, Table 2 …).
- Figures are numbered and captioned below (Figure 1, Figure 2 …).
- Every table and figure is called out in the prose before it appears.
- Every axis, column and measured value carries its unit.
- Bench work reads in the past tense, and the voice never slides between I, we and passive.
- The reference list matches the in-text citations exactly, in the style the sheet demands.
Item twelve is the one that outlives the course. Reference formatting is mechanical once someone shows the pattern, and the free writing tools include APA, MLA and Harvard citation generators that build the list from your sources — check the output against your sheet's examples, because the generator follows the style and the sheet follows the department.
Fonts, margins and spacing
Format defaults exist so that nobody grades your taste. When a lab sheet is silent, the safe choice is boring on purpose: one serif or sans-serif face at 12 points, black on white, a hand's width of nothing around every page, and enough line spacing that margin notes can breathe. The table below collects the defaults and the moments your sheet overrides them.
| Element | Safe default | When your sheet overrides |
|---|---|---|
| Font | Times New Roman, Arial or Calibri, black | Whatever readable 11–12 pt face it names |
| Margins | 1 in (2.54 cm) on all four sides | A wider left margin for binding or punching |
| Line spacing | Double or 1.5 through the prose | Single inside tables, captions and references either way |
| Alignment | Left, ragged right | Justified only if the sheet says so |
| Page numbers | Every page after the title page, one consistent corner | It names the corner — top-right or bottom-centre |
| Title page | Separate page: title, name, partners, course, teacher, date | A departmental template, if one exists — use it |
The one rule with no exceptions is sameness. A report in Calibri that meets a paragraph in Times New Roman tells the grader exactly which sentences were pasted from the manual, and a page whose spacing tightens halfway through a method reads as two reports stapled together. If you must paste, paste as plain text and reformat on arrival — five seconds now, or a circled margin later.
Numbering: pages, sections, figures and tables
Numbering is formatting that a reader can hold in one hand: "the graph on page 4", "the method in section 3", "see Table 2". Each sequence runs separately, and mixing them is the classic markup in the margin. Pages number continuously after the title page, in the header or footer, set once in the word processor rather than typed by hand. Section numbers, if the sheet wants them, stay short and flat — 1, 2, 3 with the occasional 1.1 — because a method section numbered 3.2.1.4 is a treasure map nobody follows.
Figures and tables each get their own sequence, and the numbers follow the order the prose meets them, not the order you made them. A chart you built first but discuss second is Figure 2, however proud of it you are. Every number earns its caption at first mention: the prose says "Figure 1 shows…", the caption says what Figure 1 is, and the figure itself carries axes with quantities and units. Raw data that would clog the report goes to an appendix with its own lettering (Appendix A, Appendix B), and the prose points at it without dragging it into the argument.
Figures and tables: the caption rules
The caption convention compresses to one sentence: tables are read from the top down, figures are looked at first and explained after — so table captions sit above the table and figure captions sit below the figure. Both number separately, both get called out in the prose before they appear, and both deserve a caption specific enough to be cited on its own. "Table 1. Results" tells a reader nothing; a caption that names the quantity, the unit and the conditions lets your table travel to another report intact.
| Element | Caption position | Illustrative caption (invented lab) |
|---|---|---|
| Table | Above | Table 1. Mean mass change (g) of potato slices after 30 minutes at four salt concentrations |
| Figure or graph | Below | Figure 1. Mass change against salt concentration; the band shows the range across three trials |
Those two captions come from the same invented, illustrative potato lab the other guides on this shelf use for teaching — study the shape, not the content: quantity first, unit in brackets, conditions last. Inside the frame, a graph needs labelled axes with units, a legend only when more than one series lives on it, and a scale that starts where the data starts. A table needs a heading per column with its unit, alignment that respects decimal points, and no more precision than the measuring instrument earned. To see these rules applied across a complete report with a grader's notes in the margin, the lab report example page annotates a finished lab section by section.
Five format mistakes graders circle
The same five faults produce most of the red ink on otherwise good reports, and all five are visible before anyone reads a sentence:
- The results–analysis blur. Interpretation tucked inside the results section means the analysis section arrives to find its job already done badly. Let results report and analysis interpret — the puzzle's green slots drill the border.
- Captions under tables. One lost mark per table, and the fix is a cut-and-paste. Tables caption above, figures caption below; check them in one pass down the page.
- The pasted-paragraph font shift. Manual text pasted in its original face marks the seam of every borrowed sentence. Plain-text paste, then reformat — or paraphrase into your own procedure entirely.
- Naked numbers. An axis without units, a column without a unit heading, a mean without a unit in the sentence — each one is a mark gone. Attach the unit to the number everywhere they meet.
- The padded reference list. Sources in the list that the prose never cites — or citations in the prose with no list entry — read as decoration, and graders check both directions. Match them one to one.
None of these require new science to fix, which is precisely why they hurt: they are the marks that separate a careful report from a rushed one, checked in the same first minute as the section order.
Format checked, report still thin?
A tidy shell is not a filled report. If the sections are ordered but the method reads thin, the analysis will not come, and the deadline is tomorrow morning, a quoted, deadline-bound writer can take your measurements and your manual from blank page to formatted references while the experiment stays yours. Your data, your structure, your voice. The form below is the way to ask.
What this page cannot do
The honest limits, because a page that grades format should survive an audit:
- It cannot judge the science. Green slots and full checklist bars mean the report is dressed; whether the hypothesis was worth testing and the method was sound are questions for your data and your teacher.
- It does not know your sheet. Some briefs want a discussion instead of an analysis, an abstract up front, or the aim merged into an introduction. Where the sheet and this page disagree, the sheet wins — treat the puzzle's order as the default, not the law.
- The checklist only counts honest taps. Nothing verifies your margins; the meter fills because you say it does. Its value is the twelve-second pass it forces before submission.
- It will not format citations for you. The reference rules here stop at "match the style your sheet names"; for built lists, the citation generators do the mechanical part.
- It is one shelf-mate among many. The study guides hub keeps the whole reports shelf — and its general-report sibling, the report writing format guide, covers the front-matter and numbered-TOC conventions non-lab reports use.
Quiz: five questions on format
Five questions on the calls a format makes — caption positions, section borders, defaults, page numbers and what the reference list owes. Every wrong answer reveals the right one, and four options keep the guessing honest.
1. Where does the caption for a table go?
2. Which section comes immediately after Results in the standard order?
3. Your lab sheet is silent on font. Which choice is hardest to fault?
4. Where do page numbers belong?
5. What belongs in the References section?
Frequently asked questions
What is the correct format for a lab report?
The common school shape runs: title page, then aim, hypothesis, method, results, analysis, conclusion and references, each under its own heading. The aim says in one sentence what the experiment measured; the hypothesis commits to a testable prediction; the method retells the procedure in the past tense; the results report data in tables and figures without arguing; the analysis names the pattern; the conclusion returns a verdict on the hypothesis; the references list every cited source. The puzzle at the top of this page drills that order, and the twelve-point checklist below it covers the presentation rules — font, margins, spacing, page numbers and captions — that graders check first.
What font and margins should a lab report use?
The safe default is a readable 12-point font such as Times New Roman, Arial or Calibri, in black, on a white page with 1-inch (2.54 cm) margins on every side, left-aligned prose, and double or 1.5 line spacing — whichever your lab sheet names. Use one font for the whole report: pasted paragraphs from the manual that arrive in a different face are the classic giveaway of a rushed write-up. Tables, captions and the reference list may single-space even when the prose is double-spaced.
Do table captions go above or below?
Above. The convention is captions above tables and below figures, each with its own number sequence — Table 1, Table 2 and Figure 1, Figure 2 — so a reader can cite either one from the prose. A caption earns its place by being specific: 'Table 1. Mean mass change (g) of potato slices after 30 minutes at four salt concentrations' beats 'Table 1. Results'. Every table and figure must be mentioned in the text before it appears, and every axis and column must carry its unit.
Do lab reports need page numbers?
Almost always. Put a page number on every page after the title page, in one consistent spot — top-right and bottom-centre are the usual choices — and let your word processor's header or footer place them, because hand-typed numbers drift the moment you edit. If the sheet asks for numbered sections, keep the numbers short (1, 1.1, 2) and never renumber mid-report. The title page itself usually counts as page 1 but hides the number; that is the one place a missing number is correct.
Does this page save my work?
Almost nothing. The only thing stored is the puzzle arrangement: every move writes the current section order to one local storage key, csw-lrf-v1, in this browser, so a closed tab does not lose your board. Reset erases that key and shuffles a fresh board, which makes the page safe on a shared computer. Checklist taps, quiz answers and poll clicks are never stored, and nothing is uploaded anywhere — there is no account and no server copy.
