Introduction The report should begin with a brief paragraph complete sentences that includes a statement of the problem and your hypothesis remember your hypothesis should be written as a testable statement. Statement of the problem What question are you trying to answer?
Include any preliminary observations or background information about the subject in this case the Alka-Seltzer tablet such as what the tablet is used for, directions on packaging, personal experience you may have, etc. Be sure to cite any sources. Make sure the statement is testable. In other words, can you perform an experiment that will either support or refute your prediction.
If you cannot not think of a way to test your prediction, then it is not testable. Procedure Write at least one paragraph complete sentences which explains what you did in the experiment. Your procedure should be written so that anyone else could repeat the experiment.

For instance, if you used hot water, how did you make the water hot and what temperature was it; if you chose salt water, what was the concentration of the salt water, etc. That means that even some of the most obvious steps need to be stated so there is no uncertainty. When designing the procedure, be sure to include replicating the experiment trials to ensure data is reproducible and valid. Results Write at least a paragraph complete sentences describing the results and observations of your experiment.
Here you will compare results for control groups and experimental groups and not simply list the numbers. Be sure to include calculated averages of trials.

Include a brief summary of the data—averages, highest, lowest, etc. Usually you change a parameter of the system such as changing the temperature, independent variable , and measure its effect such as the length of a metal rod, dependent variable. Specify such measurement details as the type of standard or instrument used to make the measurement for example, meter stick or vernier caliper, etc.
Give the instrument uncertainties.

You may also give, if necessary, an apparatus diagram. In our experiment, some of the items indicated under each section may not be needed. I will give you more feedback in class. I expect that, the lab reports, either typed or handwritten, should be neat, clear, and organized. Points will be deducted for these, as well as for missing units and failing to follow the outline i. Physical Measurements-phys , dr. Sections of a laboratory report : A laboratory report usually have several sections identified by titles.

Introduction : State the purpose of the experiment in general terms.

Procedure: Indicate what parameter or properties of the system you are measuring. Results : Provide tables showing your measurement with units. Describe the uncertainties: standard, instrument, random errors Provide graphs. Graphs should be neat, clear, and include the axis label and units. Computation of the final answer: slope calculation, averages, and standard deviations all in proper significant figures.
Evaluate the outcome objectively, taking a candid and unbiased point of view.
Suppose that the outcome is not close to what you expected.
