Adrianne has a master's degree in cancer biology and has taught high school and college biology.

Bacteria are rarely thought of as being good until you learn about their many uses. Your students will learn to appreciate these microbes as they read and discuss a text lesson, complete a group research activity and take a quiz.

Lesson Objectives

At the completion of this lesson, students will be able to:

  • Define 'bacteria' and 'good bacteria'
  • Identify examples of good bacteria
  • Describe how good bacteria are useful

Length

2 hours

Materials

Instruction

  • Start the lesson by asking your students to tell you what they think of when they hear the word 'bacteria.' Most comments will be negative.
  • Let your students know that there are some bacteria that are very useful to us. Tell them they are going to begin learning about the helpful bacteria as they read and discuss the Good Bacteria for the Human Body: Types & Sources text lesson.
  • Now, you will read the lesson together as a class and stop for discussions throughout the lesson. Select students to read a paragraph at a time.
  • Start by reading the lesson and pausing at the end of the 'Escherichia coli' section, then ask and discuss:
    • About how many bacteria live inside of the human body?
    • What are two types of bacteria that live in the intestines?
    • What do they do in the intestines?
  • Continue reading and pause at the end of the 'Lactic Acid and Yogurt' section. Now ask and discuss these questions:
    • What foods are created by good bacteria?
    • What bacteria ferments milk into yogurt?
    • How do these bacteria help in the body?
  • Read the 'Lesson Summary' section to your students and emphasize the main points from the lesson.
