Chemistry Laboratory Notebook
A laboratory notebook is used to explain laboratory procedures, record all laboratory data, show how calculations are made, discuss the results of an experiment, and to explain the theories involved.
A record of laboratory work is an important document, which will show the quality of the laboratory work done. As you record information in your notebook, keep in mind that someone who is unfamiliar with your work may be using this notebook to evaluate your laboratory experience in chemistry. Your notebook may even be subpoenaed in a courtroom as evidence. When you explain your work, list your data, calculate values, and answer questions, be sure that the meaning will be obvious to anyone who reads your notebook.

Chemistry Laboratory Notebook Format
Lab Title Date of Experiment
Purpose: Explain, in your own words the purpose of this lab
Background/Safety Concerns: Describe any background information a person would need to know to understand or perform this lab. Include all safety concerns relating to this lab
Pre-Lab Questions and Answers: (These are graded) Answers should clearly show your understanding of the lab and the concepts outlined within.
Procedure: This is your explanation of how you will perform the lab. For each lab you will read the “materials” and “procedure” written on your handout very carefully, you will then summarize them in this section. Pretend I am going to interview you before you can enter the lab area and my question will be “What are you going to do today?”. This section should explain the process you will use to complete the lab.
Data/Observations: Clearly record all data and observations collected during the lab, place that information in this section.
Post-Lab Questions and Answers: Answer the questions clearly and completely

Formal Lab Report Requirements
Introduction: State the objective of the lab in your own words.
Materials: List all equipment and materials used to complete the experiment.
Procedure: Provide a brief summary of the procedure you used to perform the lab.
Data and Results: Include all observations, data, and calculations from the lab (in that order). All data tables must be typed and constructed from your written work performed in the lab. Be sure to include all units and the correct number of significant figures. Show one example of each calculation performed.
Conclusion: This should always be the last thing on your report. A conclusion is the summary of how the experimental data relates to the purpose of the lab. Keywords (scientific words) should be used to help discuss what you have learned from the lab. Discuss probable sources of error and suggest plausible ways to correct those errors. The conclusion is worth the most points so use thoughtful scientific answers.
