Standard Lab Format

Title:

  • Give the name of the lab or experiment
  • Include the independent and dependent variable(s) and the relationship between them.

Problem/ Purpose

  • Write one or two sentences
  • Tell what you are solving for or the reasons for performing the lab/experiment.
  • Include how the independent will affect the dependent variable.

Background information

  • Write in paragraph form.
  • Tell the information you know about the topic before you begin the investigation.
  • Include formulas, equations, related concepts in order to clarify the lab.
  • May include a list of vocabulary terms and definitions.

Hypothesis

  • Write asentence that gives an educated guess as to the outcome of the experiment.
  • Include words: if, then, and because
  • Include independent and dependent variables

Experimental design

  • Write a list identifying the following: the independent variables, dependent variables, and controls (if applicable)

Materials

  • Write a list in column format of all the materials used to conduct the experiment.
  • Includequantity, volume of items (when applicable)
  • Do not number!! Use bullets.

Procedure

  • Describe the process or each step needed complete the lab.
  • List and number each step
  • Include enough information so that the lab could be repeated

Data

  • Record the measurements (quantative data) or observations (qualitative data)
  • My Enhanced Science class requires quantitative data!
  • Including (key word – including) qualitative data will strengthen your lab report.
  • Display measurements (quantative data) as a table, chart, graph, diagram, computer print-out.
  • Record observations (qualitative) data as statements that tell the following:
  • Sight: what did it look like? What color was it?
  • Smell: What did it smell like?
  • Taste: What did it taste like?
  • Touch: How did it feel (wet, rough, smooth, etc.)?

Discussion/ Analysis

  • Write in paragraph form.
  • In the first paragraph explain the results using evidence from the data.
  • In the second paragraph identify any trends or patterns in the data.
  • In the third paragraph identify any extraneous variables or errors and possible reasons/sources for the errors.

Conclusion

  • Write in paragraph form.
  • In the first paragraph restate purpose and hypothesis. State whether or not the hypothesis was supported, giving evidence for your statement.
  • In the second paragraphgive at least one example of how the concepts learned in this lab relate to “real life” situations.
  • In the third paragraph give recommendations for further investigations.
