Zoey, a determined student, has embarked on a fascinating science project that delves into the effectiveness of antibacterial and normal soaps in combating bacterial growth. With the rise of concerns about the impact of antibacterial soaps, Zoey aims to shed light on whether normal soap can match up in preventing bacterial growth without the associated negative side effects.

Zoey’s project kicked off with the collection of bacteria from a designated spot within her school premises. This sets the stage for a meticulous experiment where three popular brands of antibacterial soap—Softsoap, Method, Dial—will be pitted against three different normal soaps—Mrs. Meyers, 365, Wbm care. Each soap brand will be tested on three separate petri dishes, and to ensure accuracy, three petri dishes will serve as controls.

Zoey monitored the bacterial growth on days 3, 6, 9, and 12, providing a comprehensive view of how each soap influences the bacterial environment. Zoey posited that both antibacterial and normal soaps will prevent an equal amount of bacterial growth. However, she leaned towards normal soap as the superior option due to its perceived lack of negative side effects.

Zoey’s research is rooted in the concerns surrounding antibacterial soaps. Citing information from Cone Health, Zoey notes that these soaps may contribute to the creation of resistant bacteria, act as endocrine disruptors, eliminate beneficial bacteria, and pose threats to the environment. This alarming revelation underscores the importance of Zoey’s mission to explore alternative solutions without such drawbacks.

As Zoey meticulously conducted her experiment, the results provided valuable insights into the ongoing debate surrounding antibacterial and normal soaps.
