Lesson 02 – Properties of Life
Cell Structure and Function
Essential Question - What are the
properties of life?
How are living things alike?
Objectives
• Students will be able to:
– Predict qualities that make things living or
nonliving
– Explain characteristics all living things have in
common
– Predict evidence for how to tell if something is
alive
How are living things alike?

1. What does ASIMO have in common with us?
2. What makes ASIMO different from us?
How are living things alike?
Inquiry Warm-up
Discussion:
• Living Characteristics observed:
• Nonliving Characteristics observed:
Explain Vocabulary
1. Organism: A living thing
2. Cell: The smallest unit of life capable of
carrying on life's functions
3. Unicellular: Organisms composed of one cell
only
4. Multicellular: Composed of more than one
cell
How are living things alike?
What Is Life?
Redi’s Experiment
Francesco Redi designed
one of the first controlled
experiments. Redi showed
that flies
do not spontaneously arise
from decaying meat.
What Is Life?
Pasteur’s
Experiment
Louis Pasteur’s
carefully
controlled
experiment
demonstrated
that bacteria
arise only from
existing bacteria.
Properties of Life Brainstorm
Discuss these questions with a partner. Be
prepared to share your answers with the class.
• What things do you have in common with a
house cat?
• What do all living things have in common?
• How could we find out?

• Complete your tree map on the back of your
inquiry lab paper.
• We will discuss your reading when we are done.
Properties of Life
• Remember OGRRE!!
rganization: 1. Cellular Organization- made of cells
2. Similar Chemicals- water, carbohydrates, lipids, proteins, and nucleic acids

Prediction
Are Plants Living Things – Data
Collection
• In upcoming classes you will be gathering
qualitative data about your plants.
• You will continue to connect the data you collect
back to the properties of life to see if you can
see evidence of each of the properties.
Conclusion - Extend
• If you saw a glob of green ooze moving towards
you, how would you determine whether or not it
was alive?
