Presentation Transcript

  1. Writing A Physics Laboratory Report • 4 sections • Each section should be clearly titled in your personal lab report: Abstract Design Data Collection & Processing Conclusion & Evaluation

  2. Abstract: • ~ 50 words • explains purpose of experiment • States specific results including trendline relationship • Includes significance ratio (where applicable)

  3. Design • Formulate a focused research question. • Identify relevant control variables, IV, DV • describe how variables are to be controlled . • List all materials and equipment used to do the experiment. • Write a protocol that allows for sufficient data to be collected.  • BE EXPLICIT & DETAILED

  4. Data Collection & Processing • Include all tables related to the lab. • Include control variable measurements important for replicating your lab (with uncertainties). • Make sure you have units and measurement uncertainties in all appropriate column headings • Process raw data correctly • Present processed data appropriately with error bars where appropriate.

  5. Conclusion & Evaluation • Describe the relationship, significance ratio, and goodness of fit (R2 value) betweenyour variables as indicated by your graph. • Evaluate weaknesses and limitations • Suggest realistic improvements based on identified weaknesses and limitations. Be explicit about improving accuracy of measurements. • NOTE: write the conclusion in sentence and paragraph format. • Answer any questions given to you in the lab.

  6. Significance Ratio (modified Χ2) • Determine the range (R) from first to last of your multiple measurement variable. • Determine the largest of your s n-1 values (S) • Calculate Significance Ratio (R / S) • If significance ratio is > 3 your data is probably significant. % Error Formula • Find the predicted (P) value from your hypothesis or reference source. • Find the A value from your equation (m = A) • % error = 100•|(A-P)/P|

  7. The lab report is marked out of 18 points. A+ = 18 - 17 A = 16 - 15 B = 14 - 13 C = 12 - 11 D = 10 - 9 F = < 9 It is due at the late bell 3 days after you complete data collection. Late lab reports will receive academic penalty. Please take this seriously. Your lab grade is the single most important component of your final grade in this course! ...Good Luck!
