BIO W1A2:

Question 1:

Question 1: Properties of life and recognizing living and nonliving things

Consider the properties and characteristics of life. Choose two items (one of which is alive or has been alive and one which has never been alive). Compare and contrast their characteristics. What characteristics do they share and how are they different. Be prepared to discuss the importance of the various characteristics of living things and how their combination makes life an emergent part of the universe.

Question 2:

Thinking as a scientist, designing research

Consider the process by which scientists think through information and solve problems and how this is similar and different to how nonscientists approach the world. Consider a small problem that is solvable scientifically. Describe the process you would go through in solving that problem. Be prepared to discuss the significance of the scientific approach to the development and advancement of human knowledge.

2- If you wanted to carry out an enrichment experiment to enrich for nitrogen-fixing organisms in soil would you add ammonia to your culture broth? Why or why not?

3- What is the human microbiome? what are two important findings scientists have made from studying it?

Background Information: The study for this discussion was performed during the early part of the last century and involved several hundred African American males who had syphilis. Participants were not notified that they were actually part of the study and were not given treatment for syphilis, which was available during the study.

This study is a good example of how research on human subjects should not be conducted. Unfortunately, this study was fundamentally unethical in its execution and was not set up according to the scientific method. However, a discussion on this study is an excellent opportunity for students to learn how to apply the scientific method to a real- life situation.

Instructions: Go to the CDC website and review the history of the study: http://www.cdc.gov/tuskegee/

Answer one of the following questions:

1)How could a better knowledge of biology have possibly protected the participants?

2)Explain how a study of this kind could have been properly designed using the five basic steps of thescientific method.

3)Was there a hypothesis that scientists were trying to answer? If so, what was it?
