A Microbial World

Your Mission: Sample, grow, and investigate the micro-organisms around us and research their relationship with many of the products we use every day.

Microbiologists have found that microbes can live just about everywhere, even on us! We have trillions of microbes inside and outside of our bodies. 
In this activity, students will investigate the relationship micro-organisms have with many of the products they use every day and then sample, grow, and investigate the micro-organisms around
us.
