The first video explains what you put in the “Introduction,” “Results,” and “Discussion” sections of your lab report. The second video gives a different perspective on what you put in the “Discussion” section of your lab report.
Note: Most 100-level chemistry labs require only worksheets to be filled out at the completion of each lab. Therefore, this information would be most useful for 200-level students as lab reports are often required for those courses.
Now that you have completed an experiment and have collected all of the necessary information in your lab notebook and any supplementary data from analytical instrucments, you need to write up your results in a lab report. The purpose of writing reports you've performed is to communicate exactly what occured in an experiment or observation and to clearly discuss the results.
The abstract is a one or two paragraph concise, yet detailed summary of the report. It should contain these four elements:
Often, the abstract is the last piece of the report written.
This section tells the reader why you did the experiment. Include background information that suggest why the topic is of interest and related findings. It should contain the following:
Experimental (Materials and Methods)
This section should describe all experimental procedures in enough detail so that someone else could repeat the experiment. Some guidelines to follow:
The results section should present data that you collected from your experiement and summarize the data with text, tables, and/or figures. Effective results sections include:
The discussion section should explain to the reader the significance of the results and give a detailed account of what happened in the experiment. Evaluate what happened, based on the hypothesis and purpose of the experiment. If the results contained errors, analyze the reasons for the errors. The discussion should contain:
A brief summary of what was done, how, the results and your conclusions of the experiment. (Similar to the Abstract.)
A listing of published works you cited in the text of your paper listed by author or however the citation style you are using requires the citation to be listed.
