Lab 7 state functions

Cite in ACS (American Chemical Society) Abstract: Summarizes the report. This section should not be longer than 250 words. Include a short statement of the background information or main topic of the lab report. Clearly state the purpose of the study. Report the main result verbally and numerically and state whether the experiment gave the expected results and if not, why. I brief mention of the major points of your discussion should also be included. * Write this section last! It is a summary which cannot be done until all of the work of the experiment and writing of other sections is finished.* Introduction: Gives background information for understanding the rest of the report. About one page. Keep in mind your audience and organize your thoughts in a logical fashion. Include a broad description of the general topic of the report that includes definitions and any pertinent equations with citations. Progressively narrow your explanations to a more specific discussion of the studied topic including again any definitions or equations. The last paragraph should be a brief description of the current experiment as it pertains to the theory described. Any balanced chemical equations or mathematical equations need to be centered on a new line and numbered on the right hand side. Any figures (charts or diagrams of equipment) must be numbered with a caption. All definitions, equations, or information that was found from another source such as the textbook, laboratory document from Angel, or internet sites MUST be referenced with a number. Do not include procedure information. Procedure: Reference the laboratory handout on Angel. Write in paragraph form, in past tense, 3rd person neutral. Include actual values used in the experiment (masses of reagents, volumes of solutions, etc.) and any changes from the lab manual. Do not repeat the handout. Write in your words and be specific in your description. Do not include any calculations, observations, results, or data analysis information. Data: Use charts, graphs, and tables to organize your data in clearly labeled sections. Number and title every table. Have a caption for every chart or graph. An example of the calculations or formulas should be provided. Any outside information must be referenced properly. Do not include any interpretation or opinions. Results & Discussion: This is the most important section of the report and should be at least one page long. State the main result of the lab with error and compare it to expected values. Include % error or % yield if appropriate and use those results to discuss the purity of the products. Discuss any differences between the expected result and your result and identify sources of error (human error and equipment error are not acceptable sources; be specific). Interpret the results by explaining what happened during the experiment on the molecular level. Do not recite the procedure again! Reference the theory in the introduction to help explain what happened and why. Did you expect a reaction to produce a gas? Did you observe bubbles or other evidence of a gas? What gas would be produced and why? Conclusion: Summarize the main ideas of the discussion and restate the result of the experiment. Identify a broader application of the topic with a literature citation. Did your experiment add anything new, or justify a known principle or law? How does this experiment relate to the larger world of scienc Parts of a Lab Report Criteria Achievement Level Requirements (100%) Adequate (80%) Below requirements (60%) Present but does not meet (40%) Not present (0%) Title Page and Header (5% Weighting) 5 percent Title, Name, Group Member, Course Title and Code, Instructor, Submission Date 4 percent Missing 1 or 2 items from requirements 3 percent Missing 3 or 4 items from requirements 2 percent Missing 5 or more requirements 0 percent Not present Abstract (5% Weighting) 5 percent <250 words Summary of the report that includes background, purpose, quantitative results, errors, and whether the experiment gave expected results and if not, why. 4 percent Missing one component of the requirements. 3 percent Missing two components of the requirements. 2 percent Does not adequately summarize report by using the listed requirements. 0 percent Not present Introduction (20% Weighting) 20 percent Big 3: Describes big picture, then small picture, then experimental purpose. Includes all mathematical equations, chemical reactions, and content needed to understand the procedure and results. Correct literature citations (see LibGuide) relevant to any information that must be referenced. Chemical and mathematical equations centered and numbered. Figures include caption. 16 percent Small errors such as formatting or ommission of one of the Big 3 but still enough information for lab analysis. 12 percent Missing citations for referenced information OR missing essential information (equations, reactions, or concepts) needed to understand the lab. 8 percent Does not include two of the Big 3. Essential information is missing. 0 percent Not present Procedure (15% Weighting) 15 percent Past tense writing in passive voice. Reference of lab protocol. Paragraph form in the student's own words. Mentions specific factors from that experiment that could influence results. Includes details of chemicals, instruments, and software. Does not contain any results or discussion. 12 percent Incorrect tense or lack of passive voice. Lab handout is not referenced. Procedure is clear and concise. 9 percent Procedure copied from lab protocol or has procedural errors. 6 percent Procedure could not be followed to perform the lab. 0 percent Not present Data (20% Weighting) 20 percent Data displayed in easy to understand well labeled tables, graphs, and charts as appropriate. Figures are numbered with legend. Sample calculations are concise with equations numbered and centered. 16 percent Formatting omissions or inclusion of procedure information or theory. 12 percent All data is present. Step by step calculations fill pages or data is not correctly analyzed. 8 percent Data and calculations are incomplete. 0 percent Not present 25 percent Compares results obtained (important findings, not all the data) with expected results and discusses 20 percent Includes "final answer" with error analysis. Errors in explanation in terms of molecular level behavior or inclusion of 15 percent Final answer is unclear due to data being listed. Error analysis is general and does not identify possible sources. 10 percent Does not include explanation in terms of molecular level behavior or is incorrect. 0 percent Not present Results & Discussion (25% Weighting) differences. Sources of error are identified with % yield or % error as appropriate. Results are explained in terms of molecular level behavior. Refers back to theory in the introduction. procedure information. Possible small errors in explanation on the molecular level. Conclusion (5% Weighting) 5 percent Evaluates the success of the experiment with restatement of main result. Identify broader applications of the topic with appropriate literature citations (see LibGuide). 4 percent Error in final conclusion but contains requirements. 3 percent Missing citations or main result. 2 percent May restate information from the lab but statement does not meet requirements. 0 percent Not present References (5% Weighting) 5 percent Citations present in the order presented in the paper, in ACS format, from reliable academic sources (see LibGuide). 4 percent Citations include unreliable or nonacademic sources or are listed out of order. 3 percent Citations not in ACS format. 2 percent Information in the lab is included without proper citation.
