1 Organizing Your Laboratory Notebook

2 The lab notebook is a basic tool for any experimental work.
It is primarily for the experimenter's own use, but another person with similar technical background MUST be able to understand and duplicate any experiment, data, and conclusion, or to prepare a technical report by following only the lab notebook details.   It should be a neat, organized, and complete lab record. You should use a pen for all lab notebook entries.

Prelab Questions 1. Write first question here. Write first answer here. 2. 3. Etc. Page 1 Title: Lab Notebook Set-up Example Purpose: In complete, grammatically correct sentences, express the goal (the purpose) of the experiment. This should be phrased as a scientific objective, rather than a learning objective. For example, “In this experiment, the concentration of a solution will be determined” is a scientific goal, whereas “I will learn how to do titrations” is an educational goal. Materials: Write down a list (or table) of all the chemicals and equipment that you will need for the experiment. Material Material Material 3 Procedure: In full sentences write out each step of what you will do as a numbered list. Include diagrams to help describe an experimental set-up and include the name and exact amounts of chemicals measured. Write your steps here as a numbered list. (If this section goes more than one page, continue on the next right side page and label page 2, leave left blank for notes and calculations with no page number.)

9 Record data and observations taken during the experiment.
Notes/Calculations: Any and all notes, calculations, or other pertinent information goes here. This information should only pertain to the lab information on the right side, facing page . The left side page has no page number, page numbers are only on the right side page. Page 2 Data/Observations: Record data and observations taken during the experiment. Make sure your measurements are as accurate as possible with the given equipment. Use data tables when needed and be sure that all data includes the proper unit and significant figures. General observations are often useful and should be included in the procedure. Leave room for graphs and tape your printed graphs into your notebook. Tables, charts, and spaces for measurements (quantitative) and observational (qualitative) data go here. Results: Once data has been collected, analyze it – describe it completely using grammatically correct sentences. Describe how  the results relate to the purpose of the experiment. Be specific by citing the actual data values you collected during the experiment. Discuss your findings here.

10 Summarize your results - be factual and concise.
Notes/Calculations: Page 3 Conclusion: Scientific conclusions should be included in the lab notebook, especially as they inform your plans for subsequent experiments. Summarize your results - be factual and concise. Do not conclude something unless your results actually support that conclusion. State acceptance or rejection of hypothesis and give relevant evidence (3 examples of evidence). Neatness, organization, spelling and grammar count! Your laboratory notebooks MUST contain all the information that would be required for someone else to completely reproduce your experiment. Accordingly, data and information in the lab notebook must be presented in an organized, logical way. Ideally, all statements should be complete sentences and be written using correct English grammar and spelling. Keeping a neat, organized and detailed lab notebook will make writing your final reports much easier.
