1. Today’s Objective:
•Identify claim, evidence, & reasoning. 
•Use claim, evidence and reasoning as the framework of a scientific explanation. 

2. Claim Evidence Reasoning Claim Evidence Reasoning is a framework for constructing scientific explanations. Whenever you answer a question in a science class, you should use CER

What is the girls claim?

4. Fold paper in half down the middle and make a T-chart with the following headings.
Formula
Definitions

5. Copy this down on the left side of your paper under formula.

6. On the right side of the paper write down the following:
Claim:
Evidence:
Reasoning:

7. Write down these definitions.
Claim Evidence Reasoning
Claim Evidence Reasoning is a framework for constructing scientific explanations.
Write down these definitions.
•Claim: conclusion statement that answers a question
•Evidence: DATA that support the claim (tables, charts, graphs, observations)
•Reasoning: explanation of the science behind why the facts support the claim

8. Claim Evidence Reasoning http://www.youtube.com/watch?v=Ns4mnmNBk1Y
PROBLEM: Is the sham wow worth buying?
CLAIM What does Vince want you to believe? EVIDENCE
Why is Vince so convincing?
As you are watching, think about all the evidence Vincent uses to convince you to buy Sham Wow.

9. What did Vincent Claim? Claim –
•A conclusion statement that answers question
What did Vincent Claim?

10. Evidence –
•Observations
•Experimental evidence
•Facts that led you to make the claim DATA whatever you measured or observed!!!
What evidence did Vincent use?

11. What evidence does Vince use to convince you to buy Sham Wow
What evidence does Vince use to convince you to buy Sham Wow? -holds 20x its weight in liquid demonstrations - dried off the counter -washable -better for the environment -save $20 a month on paper towels -change the size -different/multiple uses -10 year warranty -Made In Germany -Germans make good things

12. REASONING How did Vincent use that evidence to prove his claim
REASONING How did Vincent use that evidence to prove his claim? The reasoning ties the evidence to the claim.

13. Reasoning
•Uses logic to tie evidence to the claim.
•Detailed explanation for why the evidence led you to make the claim.
•Deep explanation of the science concepts–Why do the facts support the statement.
–Why did my experiment turn out the way it did.
–The scientific background knowledge that justifies why a multiple choice answer is the best answer.

14. What is the Reasoning?:
The Sham Wow works so well because it contains micro fibers. Micro fiber towels are made from two synthetic (man made) materials, usually nylon and polyester. They are smaller than 1/100th the diameter of a human hair. This gives the towel a lot of surface area to make contact with the spill and absorb the liquid. ​

15. Claim Evidence Reasoning
•Smile Video – ABC news report about research into smiling.
Look for the claim, the evidence, the reasoning
(Hint – ideas will not be presented in that order.)

16. •What is the claim the reporter is making?
•What evidence does she cite in the report that supports that claim?
•What is the scientific explanation (reasoning)?
–Physiological reason smiling makes you happy
–Physiological reason people who smile feel better

17. WHY DO WE USE CLAIM, EVIDENCE, REASONING
WHY DO WE USE CLAIM, EVIDENCE, REASONING? •Use it to discuss claims made in documentaries, videos, commercials. 
•Use it after an experiment to explain why a hypothesis was proven correct or not. 
•Use it to engage in structured, respectful, argumentation.
