Adrianne has a master's degree in cancer biology and has taught high school and college biology.
At the completion of this lesson, students will be able to:
- Define microbe
- Identify major types of microbes
- Describe how microbes are harmful and useful
Cite specific textual evidence to support analysis of science and technical texts, attending to important distinctions the author makes and to any gaps or inconsistencies in the account.
Integrate and evaluate multiple sources of information presented in diverse formats and media (e.g., quantitative data, video, multimedia) in order to address a question or solve a problem.
- Copies of the lesson quiz
- Computer with projector
- Student computers
- Poster board
- Art supplies (colored pencils, markers, glue and scissors)
- Begin your lesson by asking what your students think about when they hear the word 'microbe'. Write some of their answers on the board. Students will usually give negative thoughts, so ask them if they have any positive thoughts about microbes as well.
- Let them know they may be surprised at how much they actually like what microbes do in addition to not liking the illnesses they cause. Tell them that you are going to learn more about microbes as you watch and discuss the What Are Microbes? - Definition, Types & Uses video lesson.
- Start the video and pause it periodically to have discussions with your students.
- Pause at 1:00, ask these questions:
- What is a microbe?
- Are there good and bad microbes?
- Pause at 2:30, ask these questions:
- Where are some of the places where we can find microbes?
- Are there microbes in our bodies?
- What are the five main groups of microbes?
- Pause at 5:22, ask and discuss:
- Which species of bacteria help our intestines to digest food?
- What is a helpful use for fungi?
- What are some diseases caused by protozoans?
- Play the remainder of the lesson, answering any remaining questions.
- Give your students the lesson quiz.
- Go over the quiz answers together as a class.
- Divide your students into groups of 3 or 4 and assign a species of microorganism to each group.
- Explain to your students that they are going to research information about their assigned microbe to present to the class. They can do a computer or poster based presentation.
- Give these guidelines for what to include in their presentations:
- Name of the microbe
- Type of microbe
- Where the microbe can normally be found
- How the microbe can be harmful to humans, plants, and/or animals
- How the microbe can be useful to humans, plants, and/or animals
- Micrograph pictures of the microbe
- Drawing or cartoon version of the microbe
- Each group should present their microbe presentation to the class. Encourage discussion about each microbe by asking additional questions about the microbes.
- Have your students look for current research on uses for different microbes.
