Are Viruses Alive: Sample Socratic Questions
as part of its collaboration with the SERC Pedagogic Service.
- To understand the definition and uniqueness of life and its complexities
- To examine what characteristics constitute a living organism
- To recognize the extent of the role viruses play in the movement and molding of life as we perceive it today
Context for Use
Description and Teaching Materials
Sample questions arranged in sequence for Socratic questioning regarding whether viruses are alive are listed below. These questions are based on the Are Viruses Alive? website (part of MLER) by George Rice.
- What is life? Describe attributes of life that make it distinctive from other parts of the Earth system, such as minerals, water, or light.
- What is a virus, what qualities do viruses possess that are characteristics of life (from above question), what qualities set them apart from the classic definitions of life?
- Is a virus a living entity? Why or why not? Support your answer with ideas from the previous questions.
- If you define a virus as a living entity, what are the limits of life? Discuss what qualities must be present for something to be considered alive.
(For additional discussion information regarding size constraints of organisms, see the Nanobes and Nanobacteria web page).
- If a virus is not defined as living, what is it? How does it reproduce? How have viruses evolved through time?
Teaching Notes and Tips
Tips: Prepare students for discussion by having them read credible documents about viruses and the characteristics of life (e.g. peer-reviewed papers, textbooks, etc.). Have students take notes on their readings so that they can use evidence to support their ideas during the activity. Helpful resources can be found under the References and Resources section of this page.
As in all Socratic questioning, give students time to reflect before answering questions, and make an effort to call on different students throughout the class period. Let students know at the beginning of class whether or not you will call on students randomly, or ask for hands to be raised, or both.
To explore questions about the characteristics of life fully, allow at least a full class period of 50 to 90 minutes.
During and after this Socratic questioning activity, students should be able to use appropriate terminology and integrate background readings to:
- Demonstrate an understanding of the characteristics of life and its complexities
- Apply these characteristics to assess if viruses should be considered living
- Recognize the extent of the role viruses play in the movement and molding of life as we perceive it today
Student responses should be supported by evidence from credible sources such as peer-reviewed journal articles, textbooks, meeting proceedings, etc.
Another measure of success for this Socratic questioning activity is general student feedback-this may include comments made by students regarding the activity itself, if students continue discussing/debating the topic after or outside of class time, or if students contribute to the discussion with their own thoughtful questions (during the activity itself, subsequent class periods, or outside of class).
