Seventh Grade, Microbiology Science Projects (7 results)
Microorganisms are all around us, with an amazing diversity of adaptations. They were the first life on Earth, and their relatively recent discovery in extreme environments—like hot springs, ocean vents, and polar ice—illustrates how tenaciously they've evolved and survived. Microbiology gives us insights into evolution, disease, and even the mechanisms of our own cells.
