How did Alexander Fleming use the scientific method?
Fleming reasoned that the mold must be producing a chemical that killed the bacteria. He decided to isolate this substance and then test it to see if it would kill bacteria. Fleming transferred the mold to a nutrient broth solution. This solution contained the materials the mold needed to grow and reproduce.
