Assignment steps

Understand assignment and Complete lab experiment

Before lab
  • Read over lab assignment in advance.
  • Define your objectives, prediction or hypothesis.
  • Summarize your expected outcomes.
  • If needed, do brief literature search to understand context around experiment.
During lab
  • Take detailed notes on procedures and results and note any differences in procedures or expected outcomes.
  • Record enough detail to allow someone else to repeat experiment based on your notes.
As you write your report
  • Be aware of the style of scientific writing in your discipline and grammar.
  • Write in complete sentences. Try to stay away from using "I". Use past tense. Use an active voice not passive (PDF).
This is most useful for lab reports which are based on IMRAD (introduction, methods, results and discussion). Each discipline, course, and instructor may require a different format and style for the lab report. Be sure to tailor these general steps to your specific assignment and talk to your instructor if you have questions.

Interpret & synthesize results

  • Refer to your hypothesis, outcomes or predictions as you discuss conclusions.
  • Support each conclusion with evidence from your experiment. Describe your rationale for your conclusions and any patterns or relationship your results demonstrate.
  • Compare results to the expected results and to those found in the literature (include citations).
  • Discuss the limitations of your experiment: what can't you conclude? What other interpretations may be correct? What were the limits of the methods you used?
  • Discuss how your results fit into a broader context such as practical applications or other situations, species, systems, etc.
