Discuss any possible errors that could have occurred during the collection of the data.

Assignment instructions:

You will grow a sourdough starter from scratch for one week. Next week you will divide the starter into two parts. Use one part as your control and the other as your experimental batch. You will design your own experiment with this batch.

(helpful links, do not copy any experiments given in links from instructor)



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.
