In a world where hygiene matters more than ever, one educator took a creative approach to instill the significance of hand-washing in her students. As we all know, reminding kids to wash their hands can sometimes feel like an uphill battle. However, teacher Lily Harrington decided to demonstrate the impact of germs using a simple yet effective experiment with bread.
“We conducted a science project in class last month as flu season was kicking off,” Harrington explained on social media. “We took fresh bread and exposed it to various conditions: one slice remained untouched, another was touched with unwashed hands, one with hand sanitizer, and the last one was handled after washing hands with warm water and soap. We even rubbed a piece on our classroom tablets!” After sealing each slice in a Ziploc bag, they observed the results, which were both fascinating and a bit disturbing.
The bread touched by dirty hands and those that came into contact with the devices showed significant mold growth, while the slice that had been sanitized was not far behind. “As someone who is utterly fed up with constant illness,” Harrington shared, “it’s crucial to wash your hands! And let’s be clear: hand sanitizer is NOT a substitute for soap and water!”
Though this kind of experiment isn’t entirely new, Harrington elevated it by illustrating that while hand sanitizer is better than nothing, it cannot replace the thorough cleaning that soap and water provide. Such a visual lesson is particularly impactful for young learners, making the concept of cleanliness more tangible and relatable.
Harrington, who is in her second year of teaching, noted that this was her first time conducting this experiment. “After a science lesson on leaf decomposition, we thought it would be cool to explore germs and mold from our environment,” she stated. Following their post, the experiment garnered considerable attention, but also criticism; some doubted the results, accusing the teachers of using bread that would mold on its own. Others even suggested that the experiment was an unfair attack on the classroom tablets. While Harrington clarified that the devices are usually sanitized, they opted to skip that step for the sake of the demonstration.
Interestingly, Harrington reported that many people defended their refusal to wash their hands, which she found quite astonishing. “It really was a straightforward classroom experiment to explore mold, yet it opened our eyes to how easily germs can spread.” If this experiment doesn’t inspire a renewed commitment to hand hygiene, we’re not sure what will!
