Stoichiometry Lab Report Revisions HELP SESSIONS ARE ...

Name:Date:Step 1: Reflect on your rough draft (20 points)Stoichiometry Lab Report RevisionsType up your answers to the following questions and attach this page TO THE END of your lab report.1.) Look at the rubric attached to your rough draft. Look for any 4s or 5s. What parts did you get 4s or 5s on? Why doyou think you got 4s and 5s on these parts?2.) Look at the rubric again. Look for any 3s and below. What parts did you get 3s and below on? Why do you think yougot 3s or below on these parts?3.) Do you think you did the best you could on this lab report? Why or why not?Step 2: Revise your lab report (40 points)1.) Look over the corrections Caroline made in each section.2.) Refine your lab report.3.) Go through the checklist for each section on the back of this guide.4.) Make a record of the revisions you did to your lab report.Step 3: Turn in your assignment.If any of the following things are missing, Caroline will not grade your lab report until you turn in everything.Make sure you staple the following things together IN THE ORDER BELOW!!1.) This guide and revision log. Don’t forget to put your name on it.2.) Reflection (from Step 1)3.) Your ROUGH draft4.) Your FINAL lab reportHELP SESSIONS ARE AFTERSCHOOL MONDAY (5/16) AND TUESDAY (5/17). COME GETHELP.1

STOICHIOMETRY LAB REPORT REVISION LOGFor each section:1.) Revise your lab according to Caroline’s suggestions2.) Go through the checklist to make sure you have everything. DON’T SKIP ANY PART OF THE LIST.3.) Record the revisions you made in the revision logTitle PageCHECKLIST___my title describes what I did in this lab and makes sense___I included my first and last name as the FIRST name on the title page___I included the FIRST and LAST names of all my partners___I included my teacher’s name___I included the date this lab report revision is due (Wednesday, May 18 th )REVISION LOGWrite down what changes you made to your title page below. Number each of your revisions. You may add morenumbers if needed.1.2.3.IntroductionCHECKLIST___I included information about the chemical reaction we did in class. I stated what the reactants and products were.___I stated the purpose of doing the lab AND the purpose of stoichiometry.___I gave a brief summary of the steps we took to actually do this lab___I summarized IN WORDS the math we used to calculate the amount of grams of baking soda___I summarized IN WORDS the math we used to calculate the amount of grams of sodium acetate expectedREVISION LOGWrite down what changes you made to your title page below. Number each of your revisions. You may add morenumbers if needed.2

3.4.5.Data & Observations***If for some reason you have recorded the WRONG data down or did NOT recorddata down and couldn’t do the % yield and amount of sodium acetate produced…usethe following numbers!Mass of empty flask --- 176.9 gramsMass of flask at the end of the lab – 178.5 gramsNow, do your calculations!CHECKLISTBefore the reaction:___For #1, I included a sentence describing what each of the calculations were.___For #1, my calculations are all typed up using an Equation Editor software.___For #1, all my chemical compounds are typed using the proper script. --- ex. (NOT NaCO3, but NaCO 3 – see thedifference?)___For #1, I included units for ALL my numbers (EX: not just I mole, but 1 mole of baking soda or not just 4.2, but 4.2grams of baking soda)___For sodium hydrogen carbonate, the calculations are completely accurate.___For sodium hydrogen carbonate, I explained how I got the molar mass (84.01 grams) for the baking soda.___For sodium acetate, the calculations are completely accurate.___For sodium acetate, I explained how I got the molar mass (82.03 grams) for sodium acetate.___For carbon dioxide, the calculations are completely accurate.___I put my 3 physical properties of baking soda and vinegar in descriptive, complete sentences.___I included the mass of the empty 500 mL flask and put my answer in A COMPLETE SENTENCE.After the reaction:___I included 3 observations of what happened when I mixed baking soda and vinegar in DESCRIPTIVE, COMPLETESENTENCES.___I also included 3 observations of what happened after I took the flask off the hot plate.___I included the mass of the flask after the hot plate and put my answer in A COMPLETE SENTENCE.___I correctly calculated the amount of grams of sodium acetate produced (hint – you subtract!)4

___I correctly calculated the percent yield of sodium acetate using the amount we produced and the amount weexpected to get.REVISION LOGWrite down what changes you made to your title page below. Number each of your revisions. You may add morenumbers if needed.1.2.3.4.5.6.7.8.9.10.Results & DiscussionCHECKLIST___I wrote the answer to each of the questions with complete sentences. (This means that you can’t say, “No,…..” or“Yes, I think…” – write like you are writing a paragraph).___For #1, I included a descriptive, well-though out answer to why scientists use stoichiometry and how it helped us inthis lab.___For #2, I gave solid evidence for why a chemical reaction occurred.___For #3, I explained why my percent yield was 100% or why it wasn’t. I also included my OWN percent yield in thisanswer. I gave good reasons for why my percent yield was or was not 100%.___For #4, I gave really good reasons for why scientists generally get 100% yield or not.___For #5, I explained how I would do the steps of this lab differently, NOT what I would do differently to prepare forthis lab (i.e. – you can’t say – I would have done the pre-lab questions or studied more, etc. We know labs generallydon’t go 100% perfectly, so what steps didn’t go perfectly for you? What would be a better way to do some of thesteps?)5

___For #6, I included a sentence description of the calculations that I did in this step.___For #6, I correctly calculated, using dimensional analysis, how many particles of sodium acetate I ended up withbased on the answer I got in question #7 in the data & observations section.REVISION LOGWrite down what changes you made to your title page below.
