Germ-Killing Wipes

In this activity, students get to dig into the real impact of disinfectant wipes. With one wipe claiming to kill 99.9% of germs and another at 99.999%, does that tiny extra percentage actually matter?

Kick things off with the starter slides to get everyone thinking, then jump into the main activity. There's also a challenge at the end (Can also be used as an activity for high school students).
