An error analysis will often identify specific data trials which are in error, describe the manner in which they err from the expected results and attempt to explain the cause of such errors. The axes of the graph should be clearly labeled. The equation is often written in slope-intercept form.
Elaborate discussions are discouraged. Class Data should be clearly labeled to distinguish it from data collected by your lab group. Title The title marks the beginning of a lab.
The Data section may include a table of measurements organized in rows and columns with the column headings indicating the quantities being measured. In the Discussion of Results section, the student writes, explains, elaborates, supports and cites evidence from the Data section.
The student may describe what would have been observed if a contrary conclusion were to be drawn and show how those observations were not made.
In an error analysis, the student evaluates the reliability of the data. The Purpose section should be clearly labeled as Purpose and include the purpose statement provided by the teacher. These findings become the evidence which allow you to draw a conclusion related to the question described by the Purpose.
The use of sentences and lengthy paragraphs is not necessary. When the graph is a representation of collected data, you will often be asked to determine the slope, y-intercept, regression constant and equation.
If the same type of calculation is repeatedly performed, the work only needs to be shown once.
Study each description, tape into the front of your lab notebook and refer to it often as you progress through the course. It is an opportunity for a student to express their understanding of the clear and logical line connecting the evidence Data section to the verdict Conclusion section.
The student describes how the observations and collected data support the conclusion, citing specific examples as evidence. The Data section will often include calculated data. But most of all, use it as a method of documenting and communicating your work in the lab.
The student may identify data which seem inconsistent with the conclusion and explain why such data are not swaying the Conclusion in a different direction. A Discussion of Results section sometimes includes an error analysis.
The Discussion of Results section includes an explanation of how the collected data provide logical and reasonable support for the statement found in the Conclusion. If there is an accepted answer to the question which involves a determined quantity, a percent error calculation is often performed see bottom of page.
These must be taped into the course notebook. A Conclusion is long enough to completely answer the question s which is are introduced in the Purpose section. Data sections may include diagrams of an experimental set-up with observations recorded on the diagram.
The question is written as a purpose statement and included in the Purpose section. But clearly labeled and documented findings are essential. It is often a lengthy section of several sentences and even paragraphs. The Data section will often include Class Data in addition to individual lab group data.
Equations for calculating percent error and percent difference: The reports will be divided into labeled sections with each section intended to accomplish a specific purpose. Conclusions should always include complete thoughts written using complete sentences.
The sections described below will almost always be included. Think about where you will fit the Data table, any required graphs, the Conclusion and the Discussion of Results. Conclusion If labs are thought of as centering around the investigation of a question, then the conclusion includes the answer to that question.
If the taped in addition is too big to fit the allotted space, then tape in one half of it and fold over the other half so that it fits. Discussion of Results Many labs will include a Discussion of Results section.
Every lab in every unit will come with a paragraph identifying the title and the purpose and describing the requirements for a complete lab report. Work should be shown for each type of calculation which is performed. While a lab report is by no means an art project, thought should be given to how you will lay it out on a page so as to efficiently use the provided space without sacrificing readability.How to Write a Lab Report Irina Novikova One may think that the work of a scientist is done after the experiment is completed, and its results are.
If your instructor gives you an outline for how to write a lab report, use that. 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. How to Write a Great Book Report and Summary.
6 Things the Science Fair Project. A lab report does not need to begin on its own page; it may begin following the ending of the previous lab. While a lab report is by no means an art project, thought should be given to how you will lay it out on a page so as to efficiently use the provided space without sacrificing readability.
Page 1 of 4 PH - Lab Report Writing Guidelines For each lab, you are expected to produce a “semi-formal” written report.
The purpose of a report is to convey to the reader what was done, why it was done, the observations made. Error Analysis Significant Figures in Calculations Every lab report must have an error analysis.
For many experiments, significant figure rules are sufficient. How to Write Physics Lab Reports There are three questions to keep in mind when writing lab reports.
