Overview
I just need help with some guidance or a template to follow for my lab report on food dye. This is the rubric
- Each section, following the rubric, should have a header (Introduction, Results.... etc.). You can add sub-headers as well if needed. The font for the headers and sub headers cannot be larger than a size 14.
- Use Times New Roman or Calibri as font styles for the body of the report with a font size 12.
- Number your pages but exclude the title page.
- Your report has to be double spaced.
- The introduction must be written in present or future tense. The rest of the report must be in the past tense using passive voice. This means avoid using "you", "I", or "our" in your report.
- All the sections must be in paragraph form with the exception of the results section.
- All the data collected in the lab must be in the results section in tables as the ones shown below. Create the tables in WORD and do not copy/paste the tables below to avoid any issues. The tables must be numbered and contain a short descriptive title.
- Use Microsoft Equation Editor for ALL the calculations in your report.
- Use Excel to create your calibration plot and make sure to import it as an IMAGE in your report. The image has to be clear where all the details can be read. Blurry, illegible, and screenshot images are not acceptable. Label your axis and include units. Tip for the Excel graphs: Make sure that your axes make sense. If your x-axis is labeled as 1,2,3...etc., you have an input error in your concentration data on the spreadsheet. Excel is particular at how it recognizes numbers. If the value in the table is 1x10-4, you have to input it in Excel as either 0.0001 or 1E-04.
- Your references (you can use more than 3 if needed) must follow the ACS format. A page can be found under the "Supporting Documents" Module titled " ACS Citation Sources" where you can find links to help you with the citations. Look at both and use the one that is easier for you to follow. There is also a link above in this page.
- Don't forget to also include a picture(s) of the data you collected in the lab.
we used yellow 5 and red 40 for dyes.
RESULTS SECTION:
- Follow the order and the details below and use the example tables for the results section in your report.
- The first and second table should be included twice. One for each dye.
- The last table with the corresponding calculations should be added last.
- Number all the tables as they appear in chronological order (1,2,3,4).
Table #. (Add a proper title)
| Sample | Sample Concentration (M) | Stock Concentration (M) | Volume Measured (mL) | Total Volume (mL) |
| A | ||||
| B | ||||
| C | ||||
| D | ||||
| E |
Calculations: Show the calculations solving for V1 (volume measured) for each dilution in the table above. Make sure the calculations are labeled and have proper units with correct number of significant figures.
Table #. (Add a proper title and include the lambda max)
| Sample | Average Absorbance | Concentration (M) |
| A | ||
| B | ||
| C | ||
| D | ||
| E |
Note: If the absorbance was measured twice, add the average absorbance.
Graph #: Add the graphs here and make sure to add a title for both above the graph (just like the tables). Add the graphs as images and make sure the details of the equation and R2 are added on and under the corresponding graph as instructed.
Table #: (Add a proper title)
| Name of Commercial Product | Average Absorbance | Calculated Concentration (M) |
Calculations: Show the calculation for the concentration of dye in each product. If the product was diluted, you MUST show the related calculations as well. Be thorough, add units, use the correct number of significant figures, and list the final answer in scientific notation.
