In the curriculum unit, students will develop an understanding of ecosystems that exist in and on our bodies, called microbiomes and also learn how technology has evolved whereby scientists can build machines on the scale of nanometers in order to better immunize people and fight diseases, possibly finding a cure for cancer. In focusing on microbiomes in and on our bodies, students will learn proper oral and body hygiene, which becomes critically important for students to learn at this age of puberty.
