Lab Report Guidelines for Mr. Kindt

  1. Formal labs must be in a dedicated composition / Lab notebook
  2. All labs need to be in pen, preferably black or a dark color.
  3. All labs need an appropriate title and date.
  4. The lab should be in the correct sequential order as listed on the scoring rubric.
  5. Follow proper grammar and spelling conventions.
  6. Avoid using personal pronouns (I, We, etc…).
  7. Although you often work with partners in class, each person is responsible for their own personal unique lab report.

Introduction:

-Paragraph form:  Here you list the problem or objective you are trying to answer.

-Include your overall lab question / problem here

Materials:   List the materials used in the lab (do not use sentences here).

Procedure

-Number the steps that YOU used in the lab, even if they are different from the original hand-out.

-Write steps in command form so that anyone else can reproduce your experiment.

Data & Observations

-Record all data with the correct number of significant figures (this is based on the precision of your instrument).

-Data must have correct units.

-Observations must be detailed & descriptive.  Avoid descriptions like “It turned a yellow color” replace “it” with the specific chemical that turned yellow: “Lead Nitrate solution turned a yellow color”.

 

 

Calculations & Results

-If you have to perform many repeated calculations, you only need to show one calculation in a step by step outline.

-Your final answer should contain the correct number of significant figures which will be based on the precision of the instrument being used.  Do not round during your calculations, only the final will be rounded to the correct number of sig. figs.

-Graphs need to have a title, both axes labeled with units and properly scaled.  The scaling should be such that you use a minimum of 50% of your graph.

-A “best fit” graph should be a RULER straight line that goes through an average slope of all the data points.

-Analysis of graphed data may include a calculation of the slope intercept formula:  y = mx + b  or an R2 value.

Error Analysis

-Be sure to describe the errors that were in your control and out of your control.  Saying you used a dirty beaker is not an error!  This is poor lab procedure.  You should have cleaned the beaker before you used it in your experiment.

-Describe how the error affected your results.  Don’t say “we let too much base out of our buret causing the pink indicator to turn too dark which would affect our results.”  Describe how this error would have increased or decreased the final result in your calculations.  Be specific, don’t just say this error would affect the final result!

Conclusions & Questions

-The conclusion should be at least one paragraph describe the summary of your results.  You can also discuss what you learned and what you would do differently if you were to repeat this lab.

-Make sure you include your final results with actual data.  State the correct numbers and units.

Unknown & Post lab questions

-Some labs will have a sections where you must test an unknown.  Your teacher will explain where this section will fit into your lab.

-Post lab questions should be answered in your lab notebook after the conclusion.

-ALL LABS MUST BE IN PEN AND IN A DEDICATED LAB / COMPOSITION NOTEBOOK.  NO EXEPTIONS.
