Transcript:How to Write a Lab ReportA lab report is how you explain what you did in experiment, what you learned, and what the results meant. Here is a standard format.
Title Page of a Lab ReportNot all lab reports have title pages, but if your instructor wants one, it would be a single page that states:
- The title of the experiment
- Your name and the names of any lab partners
- Your instructor's name
- The date the lab was performed or the date the report was submitted
Title for a Lab ReportThe title says what you did. It should be brief and describe the main point of the experiment or investigation. An example of a title would be: "Effects of Ultraviolet Light on Borax Crystal Growth Rate".
Introduction/Purpose for a Lab ReportUsually the Introduction is one paragraph that explains the objectives or purpose of the Experiment.
Materials Section of a Lab ReportList everything needed to complete your experiment.
Methods for a Lab ReportDescribe the steps you completed during your investigation. This is your procedure. Be sufficiently detailed that anyone could read this section and duplicate your experiment.
Data for a Lab ReportNumerical data obtained from your procedure usually is presented as a table.
Results for a Lab ReportDescribe in words what the data means.
Discussion or Analysis for a Lab ReportThe Data section contains numbers. The Analysis section contains any calculations you made based on those numbers. This is where you interpret the data and determine whether or not a hypothesis was accepted.
Conclusions for a Lab ReportMost of the time the conclusion is a single paragraph that sums up what happened in the experiment, whether your hypothesis was accepted or rejected, and what this means.
Figures & Graphs for a Lab ReportGraphs and figures must both be labeled with a descriptive title. Label the axes on a graph, being sure to include units of measurement. The independent variable is on the X-axis. The dependent variable (the one you are measuring) is on the Y-axis.
References for a Lab ReportIf your research was based on someone else's work or if you cited facts that require documentation, then you should list these references.
