The following titles and subtitles should be used for your lab report and given in this order within your lab report.

Use the following sheet as a checklist when writing lab reports. Each lab report may focus on different sections so be sure that you are focusing on the section(s) that the lab is addressing.

Should be written in the form “How is y dependant on x?” Variables Independent Dependent Controlled Variables are identified and listed correctly. Method Measuring the Variables List the apparatus used. Include a labeled diagram, if appropriate. Tools with uncertainties and quantities are clearly stated. Describe how you are going to change and measure the independent variable. Describe how you are going to measure the dependent variable. State the ranges of the independent variable you are going to use. State how many times you are going to repeat the measurements of the dependent. If a graph is going to be generated, you must collect at least 5 data points. If an average value is to be calculated, the procedure should be repeated until consistent results are obtained. Controlling the Controlled Variables Describe how you controlled other variables. Results Raw Data Both quantitative and qualitative data must be recorded. (Make sure this is raw data only.) Data tables are easy to read and clearly labeled. A title is provided. Make sure that all columns, etc. are properly headed & units are given. The decimal points should agree. Uncertainties are mandatory and can be given within column headings for equipment precision and as footnotes beneath data tables for other types of uncertainties. The number of significant figures in the measurement is consistent with the uncertainty.
