Lucy
Evolution Unit 2010
Key Words
Write what you THINK each of the following
words means on your paper.
Share your answers with a person sitting next
to you.
Copy the book’s definition of each:
1. Lineage:
Long line of ancestors
1. Hominids:
erect-walking primates that include
humans and extinct human-like species
Listen as I read the chapter introduction.
Step 1
• Listen as I read the scenario “Digging
Up the Past”.
• As you listen write down anything that you
think is interesting. You must write down
at least 3 things.
• Write a statement about the aspects of
inquiry in which the scientists were
participating (what parts of the scientific
method? CONPTT?)
Step 2
• Describe how you
think Lucy may have
looked. Use words
and sketches to
convey your ideas
• Share your ideas
with a partner
• Share your ideas
with the class
Step 3
• Describe 3 things Lucy might have done
during a typical day and how she would
have gone about doing them
• Share your ideas with a partner
• Share your ideas with the class
Key words
• Come up with your own definition for
the following words
1. Evidence:
proof
2. Inference:
derive a conclusion from facts
Step 4
Evidence Inference
Step 5
• Listen and fill in your T-table with
examples as I read the following
information about how scientists use
evidence and inference to gain insight
into the past.
Step 6
• Write 1-2 short PARAGRAPHS that
summarize how you think a scientist
would explain how the lineage that led
to Lucy changed over time. Explain
how the lineage changed form an
ancestral population that was not
bipedal to a population that was
bipedal.
Analysis
1. Compare hominids from Lucy’s lifetime with
hominids living today (humans) by answering these
two questions
a. Do you think there have been more changes in the
physical characteristics of the body (such as hands, feet,
head, and posture) or more changes in how hominids
lived (types of shelter, ways of getting around and ways
of gathering food)
b. Do you think the process that cause change in physical
characteristics are the same or different from the
processes that cause change in how hominids build their
shelters? Explain your answers.
2. Examine the answers you gave to steps 2
and 3 and answer the following.
a. Which aspects of your descriptions did
you base on evidence?
b. Which aspects of your descriptions
were inferences related to evidence?
c. Which aspects of your descriptions
were guesses?
