NES: Properties Of Living Things:Searching For Life On Mars
Presented by: Marti Phipps
Properties Of Living Things:
Searching For Life On Mars
Introduction
• Use personal definition of life to determine if life exists in three soil samples.
• Make observations and illustrate findings
National Standards• Science as Inquiry• Chemical Reactions• Structure and Function in Living Systems
• Cells and Biological Evolution• Earth’s history
ObjectivesStudents will:• Form an operational definition of life.
• Conduct simulated experiment with soil samples similar to the experiments on the Mars Viking Lander.
ObjectivesStudents will:• State relationships between the soil samples using their operational definition of life.
•Make an inference about the possibility of life on Mars based on data obtained.

Let’s pause for questions from the audience
Is it alive?
Discussion Questions
• What are some characteristics of living things?
• What are some characteristics of nonliving things?
• How are living things different from nonliving things?
