Concept #1: Scientific Method

Concept #2: Predictions, Hypotheses, & Theories

Example #1: A scientist observed a new phenomenon and wonders how it happens. What is the next step in their study?

Practice: Which of the following shows the best order of steps of the scientific method?

Practice: A scientist observes that even after sterilizing a broth, cells reappear in the broth over time. The scientist then asks: “Why do cells reappear in the broth after sterilization?” and designs/conducts an experiment. Considering this, appropriately label each of the following blanks as either a “prediction, hypothesis or theory.”

________________: Cells will only appear in the broth exposed to a source of preexisting cells.

________________: Cells appear only when preexisting cells grow & divide; therefore, cells only appear in exposed broths.

________________: All organisms consist of cells & all cells come from preexisting cells.

Concept #3: Basic Theories of Biology

Practice: Which of the following statements about the cell theory is false?
