Write a lab report which details what you did with your experimental half.
Remember, you grew the sourdough for one week, then divided it.
Use one half for the control and one half for your own experimental design. Be very complete in telling hypothesis, methods, how will you gather data (what are you watching for, how will you know you have change, etc.) Here is a lab report template to use.
Lab Report Template
i) Title: A brief, concise, and descriptive statement (not a question)
ii) Problem: What question are you trying to answer?
iii) Preliminary Observations and Prior Knowledge: Background information about the subject
iv) Hypothesis: A possible solution to the problem
Must be testable
Write in the form of a question
v) Parts of the Experiment:
What is the…
a. Control group?
b. Experimental Group?
c. Independent variable?
d. Dependent variable?
vi) Results (Data/Observations):
- Measurements, observations, notes made during the lab, etc.
- Tables, graphs, charts, etc. (label appropriately).
vii) Analysis:
- Summary of the data (averages, highs, lows, etc.).
- Helps reader understand what the results mean.
viii) Conclusion:
- Accept or reject hypothesis (was the hypothesis correct).
- Why the hypothesis was correct or incorrect.
- Discuss any possible errors that could have occurred during the collection of the data.
ix) Real Life:
- What is one thing that you have learned?
- How does this experiment relate to the real world?
