Lab Report Guidance: Key Points for Accurate Analysis

Ensure comprehensive lab reports by labeling calculations, considering significant figures, including qualitative data, suggesting lab improvements for better accuracy, focusing on grammar and spelling, and explaining scientific concepts thoroughly. Address errors, discuss effects of errors on results, critique lab setup, emphasize calculation accuracy, justify discrepancies, and note critical time factor in experiments.

Presentation Transcript

  1. Lab Reports

  2. Things to remember… • Label what the calculations are for • Watch sig figs • Include qualitative data • Improvements on lab itself-not how you did the lab • Watch GRAMMAR and spelling. • Overall-need more explanation of scientific concepts in analysis/conclusion.

  3. Errors • How would those errors affect the results? • Comment on how the lab is set up, not “we may have measured wrong”, instead something like-”we should have measured the volume with a graduated cylinder rather than a beaker because it is more precise” • Why are those errors important/relevant?

  4. Cu/Ag lab specifically • Ratios in balanced equation should match what you calculated. • If your calculations seem way off (ratio of 1:30), you need to have a reason why. • Major improvement/error was length of time it reacted. We assumed all the AgNO3 reacted, but we only let it go for 30 min. We should/could have easily tested to see if all AgNO3 was gone from solution.
