Lab report writer help: from raw data to a clear report
The experiment took an hour; the lab report takes the whole weekend. Attach your data sheet and the lab handout, and your agent processes the numbers in Python, makes a properly labeled graph and results table, lays out every section with what it must contain, and gives feedback on the discussion you write so the report stays yours.
The prompt
- Help me with my lab report for [EXPERIMENT]. Course: [COURSE]. The lab handout and my raw data are attached: [HANDOUT AND DATA FILES]. Process the data in Python: means, uncertainties or standard deviations, and any values the handout asks for, with the formulas shown. Make a results table and a graph as PNG (axis labels with units, a title, error bars and a trend line if it fits). Give me the structure of each section (title, abstract, introduction, method, results, discussion, conclusion, references) with what must go in it for this experiment. Do not write the discussion for me: here is my draft [MY DRAFT], give feedback on it, especially on sources of error. Format references in [CITATION STYLE].
What to change
- [EXPERIMENT]: E.g. "the effect of temperature on enzyme activity (catalase)", "titration of NaOH with HCl".
- [COURSE]: E.g. "AP Biology", "General Chemistry Lab", "Physics 1 lab".
- [HANDOUT AND DATA FILES]: Attach the lab handout (PDF or photo) and your data (Excel, CSV or a photo of your lab book).
- [MY DRAFT]: Paste or attach your draft discussion, or write "not started" to get the structure first.
- [CITATION STYLE]: E.g. "APA", "ACS" (chemistry), "CSE" (biology), or the style your instructor gave.
Example result
- Lab: effect of temperature on catalase activity
- Course: AP Biology. Data: oxygen produced (mL in 60 s), 3 trials at 5 temperatures.
- Results table
- • 10 °C: trials 4.1, 3.8, 4.4. Mean 4.1 mL, SD 0.3
- • 20 °C: 7.9, 8.4, 8.1. Mean 8.1 mL, SD 0.3
- • 30 °C: 12.6, 13.2, 12.3. Mean 12.7 mL, SD 0.5
- • 40 °C: 14.8, 15.6, 15.1. Mean 15.2 mL, SD 0.4
- • 50 °C: 6.2, 7.0, 5.5. Mean 6.2 mL, SD 0.8
- Graph
- Line graph of mean O2 volume (mL) against temperature (°C), with SD error bars. Rate rises to a peak near 40 °C, then falls sharply at 50 °C. The bigger spread at 50 °C fits an enzyme partly denatured.
- What each section needs
- • Title: variable and organism, e.g. "The effect of temperature on the activity of catalase from potato"
- • Abstract (about 150 words): aim, method in one line, key result with numbers, conclusion
- • Introduction: enzymes as catalysts, active site, effect of temperature on kinetic energy and denaturation; hypothesis with a reason
- • Method: past tense, passive voice; independent, dependent and controlled variables (substrate concentration, volume, pH)
- • Results: the table and graph with numbered captions; describe the trend with numbers, no explanation yet
- • Discussion: explain the trend with biology, compare with expected values from your sources, evaluate errors, suggest improvements
- • Conclusion: answer the hypothesis in 2–3 sentences
- Feedback on your discussion draft
- • Good: you explain the rise with more collisions between enzyme and substrate.
- • Add a number: say the optimum appeared between 30 and 50 °C, and that testing at 35 and 45 °C would locate it better.
- • "Human error" is too vague. Name the specific errors: time lag starting the stopwatch, gas lost before the tube was sealed, temperature drop after the potato was added.
- • Say which errors are random (wider spread at 50 °C) and which are systematic (gas leaking every trial gives readings that are all too low).
- • Your last sentence says the hypothesis was "proven". Use "supported": one experiment cannot prove it.
How to do it with todo.is
- Fill in the experiment and course, attach the handout and your data, and add your draft if you have one.
- Send the to-do in todo.is, or forward the files to your agent on WhatsApp or Telegram.
- Download the graph and the results table, and use the section checklist to write each part.
- Send each section as you write it and ask for feedback. Ask for the calculations as an Excel file to include in an appendix.
Tips for a better result
- Every number needs a unit, and every graph axis needs a label and unit. Missing units are the most common lost marks.
- Results describe; the discussion explains. Keep "because" sentences out of the results section.
- Name specific sources of error and how each one would change the result. Avoid "human error".
- Write the method in past tense passive voice ("The solution was heated...") unless your instructor says otherwise.
lab report writer: FAQ
- Will it write the whole lab report? This prompt processes your data, makes the graph and gives structure and feedback, but leaves the writing to you. Most schools treat a fully AI-written report as misconduct, so follow your course's AI policy.
- Can it make graphs from my lab data? Yes. Attach Excel, CSV or a photo of your data table. Your agent plots it in Python with labeled axes, units, error bars and a trend line, as a PNG you can insert.
- How do I calculate percent error? Percent error = |experimental − accepted| / accepted × 100. Your agent shows the calculation with your numbers and tells you whether the difference is within your uncertainty.
- What citation style should a lab report use? It depends on the subject and instructor: APA is common, ACS is used in chemistry and CSE in biology. Check the lab handout.
