Refresher: How to Write a Lab Report It has been about 10 weeks since we had one. . .
Sections: • Intro • must have Background, Purpose, Method • one paragraph • Apparatus/Procedure • Written in paragraphs • Written in 3rd person, not 2nd • Data • In Tables, on graphs, well labeled and scaled • If you do accuracy, can include on Data table
Sections continued. . . • Results • Tell me about your data • Give equation that models your data • Equation should be in physics variables • Give units and meaning of all parameters (slope, y-intercept) • Error • Discuss sources of error • Discuss precision, uncertainty • Give Accuracy, discuss
Conclusion • Summarize results • Give physical interpretation of results (what does the experiment mean?) • Discuss some of the following: • Errors, how they could be improved • How experiment could be extended or strengthened • Application of experiment to background • Practical applications • Application to physics ideas
Grading • I’ve been grading 5 points per section • Six 6 sections x 5 points/section = 30 points • Usually, longer lab reports = more points on some sections (usually results) • Or when we’ve written report over two classes • Can evaluate section grade: • 5 - 4.5 = A; 4.4 – 4.0 = B; • 3.9 – 3.5 = C; 3.4 – 3.0 = D • 3 > F
