Experimental Design
A student placed a disk of filter paper in each of the following solutions: disinfectant 1,
disinfectant 2, disinfectant 3, and distilled water. While the four disks were soaking in their
respective solutions, she streaked a sterile nutrient agar dish with a culture of E. coli bacteria.
Then, she placed each disk carefully onto the nutrient agar dish, placed the lid on the dish,
taped it shut, and incubated the dish at 37ºC for several days. Figure 19-4 shows how the
nutrient agar dish looked on Day 1 and Day 4.
