Third Grade Microbiology Science Projects (3 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. Explore our collection of microbiology projects to learn more about these tiny and amazing organisms.

Have you ever wondered how yogurt is made and what makes some yogurts different from other yogurts? You may have noticed that most yogurt containers advertise that the yogurt contains "live cultures." This means that there are living bacteria in the yogurt! These amazing bacteria can turn plain old milk into a yummy yogurt treat. In this science project, you will investigate whether the bacteria affect what the yogurt feels, tastes, and smells like by making your own yogurt at home! Read more
