Claim Evidence Reasoning
What do the terms claim, evidence, and reasoning make you think of?
How to Scientists’ Think
They think using a series of methodical process of forming claims, doing
research to collect evidence, and then using scientific principals to form
reasoning.
CER Model
Claim
Evidence
Reasoning
• a statement
that answers
a question
• observations,
data tables,
graphs,
pictures that
support the
claim
• scientific
principles,
readings,
formulas
that describe
why the
evidence
supports the
claim
Science is everywhere!
• Science is not
something that
scientists do behind
closed doors in labs.
• We all use science and
its processes in daily
mundane life to answer
questions and to form
thinking.
For Example
• If the Focus Question is, “Who is the best NFL
quarterback?
• Lets use the CER model to answer this nonscientific question….
CER Model
• Claim: Drew Brees is
the best quarterback in
the NFL.
CER Model
Evidence:
His completion
percentage is 59.4 and
he has 36 touchdowns
in his career from 20122013.
The evidence includes data.
CER Model
Reasoning:
According to Sports
Illustrated, Drew Brees
is able to adjust to the
defense during the game
and come back with a
different plan of attack.
You may use information
from text to support your
claim and evidence.
We use science everyday to make
decisions and form our thinking.
So technically, we all are scientists!!!
