Bacteria are ubiquitous, and live within the human gut, and in every corner of our environment. We come in contact with bacteria on a daily basis. Handwashing is 99.9% effective at decontaminating ourselves from bacteria which may reside on the skin. Thus, when the proper safety precautions are taken, colonies of microorganisms can be safely isolated from homes, yards, gardens, etc. The majority of microorganisms are non-pathogenic, but bacterial cultures or petri plates containing any type of bacterial colonies should only be treated with general safety precautions. Household bleach at 10% strength, or general common household cleaning reagents (409, Fantastic, Lysol, etc.), are effective at decontaminating all bacteria, and should be used at the completion of the study.

I go to a standard high school, but I'm thinking of enrolling elsewhere and I wanna know how they are. If anyone does know anything about them, do you know if they have good science programs as well? I do want to keep experimenting in school. Thanks again!
