Sourdough

1. Save a copy of the
3. (or open up your rough draft if you have one started)
4. Finish 14 days worth of feeding/back-slopping your starters.
5. Submit your data:
6. Fill out this
8. with your Sourdough Datasheet for your first treatment (all-purpose flour, dark, warm, outside, etc, whatever you chose)
9. Fill out the same
11. again with the data from your second treatment (wheat flour, light, cold, inside, etc, whatever you chose).
12. Open up your posts from the previous 2 weeks’ worth of lab. What observation did you write about to explain why there might be differences in the number or diversity of microbes between your two treatments? If you haven’t done this yet, start there.
13. Your next task is to see if anyone else noticed the same pattern you observed.

• Open class data results here: (
• )
• Toggle between tabs along the bottom of the spreadsheet to pick the experiment you were focused on. (See video below for an example)
• Take a peek at all of the graphs to see what you notice.
• Simplify the graphs by deleting the entire row for flour types or water types that you are not interested in showing on the graphs. You can include as many as you want, but there are currently too many flour types to see a clear story.
• Pick 3 graphs to include and write about in your lab report.
• Customize anything you want: colors, font, etc.
• Note about the graphs: The averages are pre-calculated for you (you are welcome!! This is an example of course evals changing this course for the better! If you have not yet filled out the , please do so!), but sadly, standard deviation was too tricky to auto-calculate and integrate into each of these graphs in google sheets, so keep in mind that these graphs should have error bars, but making them automatically update for you made my head spin– so let’s keep it simple for now, but promise in the future you will always add error bars to graphs showing the variability in raw data represented by average values. Deal?

1. Paste graphs into your lab report.
2. Write a descriptive figure caption for each.
3. Include your takeaways from these graphs in your results and try to explain why in your conclusions section. Number each figure so you can refer to each one in your writing.
4. Remember to include photos in your lab report of:

• Your starters
• Your petri dishes with growth

1. Fill in all of the lab report template sections
2. Read through your lab report to proof read, and make your writing as clear and simple as possible.
3. Submit!

Conclusions

Why does it matter? Think back to the reader you hooked in with your clear purpose statement. Tie it all back to what mattered to them in the beginning and what these results could mean for the broader concept you were studying with this experiment. Propose any ideas that you would be curious to pursue next. Include at least one sentence in your own words (avoid direct quotes) that compares what you found to the findings in a scientific, peer-reviewed article (Google Scholar) and cite this reference in the text

Experience

Share 1) one part of the lab this week that you enjoyed or found interesting, and 2) one way this lab could be improved for future classes of the same modality. I know being in person can make certain labs more impactful, like gram staining, microscopy etc., but try to come up with ways the experience could be improved for someone else taking this course in the same way you are experiencing it.
