A lab write up is a clear and consistent outline of your process of recording information. This paper is to give you basic outline of lab writes used, especially in high school.

    Determine the problem you are attempting to solve, or what you are testing. Phrase this at the top of the write up.
  2. Do a Lab Write Up Step 2.jpg
    Determine your theoretical solution to the problem or predicted outcome to the test, and call it a "Hypothesis". Use an "If this, then that, because of this" format for writing your hypothesis. Have "If this" be what you changed", "Then this" be your result of changing the hypothesis. "Because of this" is why the reaction occurs.

    Then write your materials that you used in a clear, concise list. This will allow anyone to repeat your experiment, and verify your claims.

    Write the exact steps and measurements you took, after your material list. Once again, this allows someone to replicate your experiment.

    After writing this, record your observation in clear, logical manner. Organize data and categorize the data so it is easy to read and understand.

  • Pick a lab that you know best and feel confident about. Then you can write more details.
  • Ask your teacher for guidance if you are not sure what format to use.
