Bacteria need both food and water to survive and reproduce. What provided
  these to the bacteria in your experiment? Do you think dairy products might
  provide a good source of food and water for bacteria to grow?


 
  What will be an ideal response?

Question 2

What are some possible explanations for your results? If you had unexpected
  results, what might have happened to contaminate your samples of potato?
  (Hint: Is the raw milk the only source of bacteria in the experiment?)


 
  What will be an ideal response?

Answer to Question 1

The potato provided a source of nutrition and water. Potatoes are a rich source of
water and nutrition; therefore, they provide a good medium for bacterial growth



Answer to Question 2

Bacteria are present on all surfaces and in the air. The untreated potato could have
been contaminated very easily from any of these other sources.
