Activities explore the good that microorganisms do in food production, and the harm they can do in causing disease.
This guide contains background information about how microorganisms can be both good and bad, and directions for three activities that will help students better understand how microorganisms can be helpful and harmful. The activities are most beneficial to students when completed in order. This guide is specifically designed for sixth grade classrooms, but the activities can be modified for students at other levels. A separate activity guide, titled “What is a Microorganism?” provides a general introduction of microorganisms and their role in Zion National Park.

Just as there are millions of different species of plants and animals in the world, there are millions of different species of microorganisms. Microorganisms can survive in environments where humans are unable to live. Microorganisms exist throughout the world, from Antarctica to your kitchen, from inside animals (like humans), to the expanse of wilderness in Zion National Park. Most are good, others are bad, and a few are just plain ugly.
