1. Lab Report How To

2. Lab Reports Organization – Title Page, Results, Calculations, and Discussion/Conclusion, References, Format Double spaced, 11-12 point font No personal pronouns – no “I”, “we” “she” “he” Values and equations should be properly superscript or subscript IE C2O4 should be written as C 2 O 4

3. Title (Cover Page) Title header (clear and large), name, the date, class section, lab partners, and lab TA

4. Results Usually will have Raw Data Table (will be on pbworks, the numbers you will be analyzing) Calculated Data Table: Your data you calculated via excel for each class member Figures: Usually graph or histogram form

5. Data Tables Titled Have clear, labeled columns, with units and proper sig figs Figure 1: Part A Results for Calcium Iodate Without Calcium Ion V of Thio sul Used (L) Mol Thio Used (mol) Mol Iodate (mol) Equi Conc Iodate Ion (M) Equi Conc of Calcium Ion (M) M Sol of Cal Iodate (M) Ksp Cal Iodate % Error Ksp Ka Values T1T10.00823.69E-04 6.15E- 054.66E-032.33E-03 5.06E- 084.33 4.20E-06 T2T20.0085 3.A83E- 04 6.38E- 054.73E-032.36E-03 5.29E- 08 4.54E- 06

6. Graphs – titled, clear axis Graph 1: ln(Ksp) versus 1/Temperture

7. Graph 2 -- Histogram

8. Calculations Calculations: may be handwritten in blue/black pen or typed Proper sig figs Show example calculation just for individual values grams of CO 2 =20 g CO 2 x (1 mol/44 g CO 2 ) = 0.45 mol CO 2

9. Discussion/Conclusion 1 page double spaced Keep it short, concise, to the point Highlight specific trends that strongly supports your analysis Clearly state your quantitative data that you are observing.

10. What to consider in your lab report Compare expected results with those obtained. Analyze experimental error precision and accuracy and how errors affected your results Relate results to your experimental objective(s) and theories. how significantly did one aspect of your experiment affect your results, and why? Compare your results to similar investigations. Compare between class data or other sources Analyze the strengths and limitations of your experimental design. What can be improved to reflect the theoretical background?

11. Reference Keep a consistent and clear format, usually MLA is best Always will have reference – cite your blue manual and lab handouts and other sources used.
