## Lab Reports Example | Sample and Templates for Beginners

Introduction: How is the circumference of a circle related to its diameter? In this lab, *how to write a lab report physics high school*, you design an experiment to test a hypothesis about the geometry of circles.

This activity is an introduction to physics laboratory investigations. It is designed to give practice taking measurements, analyzing data, and drawing inferences without requiring any special knowledge about physics. Make sure you record what you do as you do it, so that the procedure section of your report accurately and completely reflects what you did.

Some helpful hints for taking and recording data are in the lab tips and in the grading rubric. Note: As the semester progresses, you will be expected to take more and more responsibility for deciding how to analyze your data. Drawing valid inferences from data is a vital skill for engineers and scientists. The instructions for analyzing data for most labs will not be as detailed as the instructions below. A sample lab report for this activity is provided as an example for you to follow when writing future lab reports.

In this investigation, we examined the hypothesis that the circumference C and diameter D of a circle are directly proportional, **how to write a lab report physics high school**. We measured the circumference and diameter of five circular objects ranging from 2 cm to 7 cm in diameter. Vernier calipers were used to measure the diameter of each object, and a piece of paper was wrapped around each cylinder to deterimine its circumference. Graphical analysis lead to a less precise but equivalent estimate of 3.

However, only a narrow range of circle sizes were analyzed, so additional data should be taken to investigate whether the constant ratio hypothesis applies to very large and very small circles. Five objects were chosen such that measurements of their circumference and diameter could be obtained easily and would be reproducible.

Therefore, we did not use irregularly shaped objects or ones that could be deformed when measured. The diameter of each of the 5 objects was measured with either the ruler or caliper. The circumference and diameter of each object was measured with the **how to write a lab report physics high school** measuring device in case the two instruments were not calibrated the same.

The circumference measurement was obtained by tightly wrapping a *how to write a lab report physics high school* piece of paper around the object, marking the circumference on the paper with a pencil, and measuring this distance with the ruler or caliper.

The precision of the ratio can be estimated using the error propogation formula:. Another way to visualize and calculate this constant circle ratio is by graphing the circumference versus diameter for each object.

Graphs are especially useful for examining possible trends over the range of measurements. If C is proportional to D, we should get a straight line through the origin. From our numerical results, we would expect the slope of the C vs. The slope of the best fit line is 3. The intercept is essentially zero: The R squared statistic shows that the data all fall very close to the best fit line.

If all the data lie exactly on the fitted line, R squared is equal to 1. If the data are randomly scattered, R squared is zero. Our results support the original hypothesis for 5 circles ranging in size from 2 cm to 7 cm in diameter.

The line has an intercept The larger uncertainty from the graphical analysis suggests that the random measurement errors may be larger than estimated in the numerical analysis. The uncertainty in the measurements could be due to the paper-wrapping method of measuring the circumference, circles that may not be perfect, and the limited precision of the measuring devices. The use of paper to measure the circumference was probably the most significant source of uncertainty. It is unlikely, however, that this measurement technique biased our results, since the technique probably gave measurements of C that were too high in some cases and too low in others.

Questions Although questions are not part of a formal lab report, they should be answered on a separate sheet of paper and attached to the report where applicable. Important Reminders for a Lab Report 1) Spelling 2) Significant figures and units regarding measurements and calculations 3) Avoid personal pronouns.
