sample lab reports...anyone have any they would be willing to share?


Recommended Posts

I love this one.  Not really a sample, but a quick reference.

Name(s)

                                                                                                                                                                         

 

Title: Concise and Informative.  Not usually a sentence

The following sections in red are not usually included in a dissection report.  These sections are required in other science lab reports.  The Introduction section is usually omitted in most types of reports.

Question – The question generated by you, the teacher or the activity. (complete sentence)

Hypothesis – A suggested answer to the question.  The answer here is  a prediction about what will happen before you make a procedure, experiment, or research.  Do not write I think!Remember, your hypothesis must be measureable!

Hypothesis- If __________________________, then ____________________________. The hypothesis is a single sentence that discusses how you will solve the problem. The statement after “if†is the independent variable. The statement after “then†is the dependent variable.

Introduction- The objectives of the experiment, and its significance (why it was done).â€The main purpose of this activity…† “The goal of this lab…   This is commonly included in a dissection report

 

Materials -            Beaker                               Scale                   (If these were the materials

                             Ruler                                  Thermometer              used in the lab then this

                             Graph paper                      Microscope                is what this section should

                             Sand                                  Water                         look like.)

 

Procedure – 1)  Step-by-step instructions for the lab.

                    2) Do not write the word step.  It is implied.

3) The numbers for this section line up even if one of the steps involved takes more    than one line to write.

4) All the how to dos and what to do must be explained in the procedure.  Nothing can be assumed.

                    5) Anybody should be able to complete your experiment by reading your procedure.

                    6) Do not use personal pronouns or peoples names in this section.

 

Results – This section is written after you have completed your experiment.  In this section you simply state what happened during the experiment.  If there are applicable tables or graphs they would be included in this section.  Do not explain the results here.

 

Conclusion – This section is written after you have completed the Results section.  In this section you explain why you got the results you got and what they mean.  You discuss if the results prove, disprove, or do not apply to your hypothesis.  You also redevelop your hypothesis in this section if needed, explain sources of error, and relate anything you have learned by completing your experiment or lab.  Do not use personal pronouns in this section.

Lab Notebook

  • All labs must be written in pencil and be submitted to the teacher in a spiral notebook
  • Always use third person (no personal pronouns) when writing all parts of a lab report.
  • The following things should be written clearly in marker on the front cover :
  1. "Subject" Lab Notebook
  2.  Teacher name
  3.  Student name, and period
  4.  Number each page of the spiral notebook in the lower right hand corner
  • Page 1:
  1. Write the subject,
  2. Year,
  3.  Student name,
  4. Class period,
  5. Teacher name.
  • Page 2:
  1.  "Table of Contents" written at the top and two columns, one for "Page" and the other for "Lab Title".
  • Begin writing the first lab on page 3 of you notebook

Writing the Lab Report:

  1. Title (center on top line; on the right of line 2, put date & lab #)
    The title should indicate clearly & concisely the subject and scope of the report. 
  2. Introduction
    The introduction should give background information about the experiment. It should also state the purpose of the investigation. This section will be one or more paragraphs in length.
  3. Hypothesis
    The hypothesis should be a single statement telling the exact thing you are trying to prove in your experiment.  Never write this statement using "first person".
  4. Materials
    This section should be written in paragraph form and name all of the materials and equipment used.  Be sure to include specific amounts and concentrations of chemicals used. 
  5. Methods
    This section includes one or more paragraphs explaining the step-by-step procedures used.  The description should be so thorough that someone else could use your listed materials and procedures to conduct the same experiment and get the same results. 
  6. Results
    All data should be collected and organized in a logical order.  Results should be illustrated as charts, tables, graphs, &/or diagrams. All graphs should include a title, the independent variable labeled on the horizontal axis, and the dependent variable labeled on the vertical axis.  All lab questions and answers should be included also with this section. (Number and underline the questions & then write the answers)
  7. Error Analysis
    Include any important factors that you think may have actually affected your results.
  8. Discussion and Conclusion
    Discussion is the most important part of your report, because here, you show that you understand the experiment beyond the simple level of completing it.!! This is where you give a detailed account of what happened in the experiment. Explain all observations and results in your experiment. Analyze and interpret why these results were obtained. Be sure to tell the significance or meaning of the results.  Restate the original hypothesis and explain whether the experiment succeeded. If the hypothesis was not correct, you should analyze why the results were not as predicted. Explain experimental errors that appear in the results.

This isn't a lab report, because it doesn't have a hypothesis or conclusion.  Instead it is a procedure manual for standardizing collection procedures across different locations.

 

However, I was pointing out to ds this morning that it is a great example of materials and procedures.  This is an area where my older kids have always wanted to skimp, because when you are doing a lab from a curriculum, the materials and proceedures are already listed.  It seems like it is just copying.  It can feel like a non-sciency step.  But it really is important for replicability.

We could do a collection and compare our results with the results from Tacoma or Miami.  If we don't have facilities for a step, such as the wet peroxide oxidation, we need to indicate that it wasn't done, because all of our results would read higher than places where that step is taken.
