1. Comp. Notebook Pg. 15: Homeostasis Lab Post-Lab Questions (CSRQ or Write Down)
What body systems had to work for your body to maintain homeostasis and not overheat during exercise?
Explain why an increase in heart rate and breathing rate accompanies exercise.
Describe what EACH body system did to maintain homeostasis and keep your body going for the entire exercise time? (You must talk about the functions of some organs in the body systems to help describe this.)
We graded/went over these at the beginning of class.

2. Claim Evidence Reasoning (CER)
(4.5.16) Comp. Notebook Page 16:
Claim Evidence Reasoning (CER)

3. (4.5.16) Pg. 16 CER Box-Chart Copy in your comp. notebook
Question:
Claim (What’s your answer to the question asked?)
Reasoning (Explain why or how your evidence supports your claim?)
Evidence (Tell how your evidence supports and explains your claim and reasoning. Be specific.)

4. CLAIM
Most problems that need solving originate with a guiding question.
Most laboratory’s start with a question too.
Your claim is the statement that answers your original question.
The claim is one sentence in length.
The claim must be accurate, specific, and completely answer the question.

5. CLAIM Commercials make claims for you to want to buy their product.
Think of some claims made. Can they be proven?
Examples: 1st Hour: Sham-wow, oxy-clean, gieco saves you 15% off car insurance
2nd Hour: Verizon has the best coverage, Jake from state farm will ans. the phone at 3 am, kickstart 3 things together are awesome, best cleaning supplies
3rd Hour: Mascara best brands, most absorbant diapers, best toilet paper, AT&T vs. Verizon, KFC is it finger-licking good, Pro-active works
5th Hour:
6th Hour:
7th Hour:

8. REASONING
Reasoning is the explanation that connects your claim to the evidence that supports it.
It shows why the data you chose counts as evidence.
This explanation acts as a “conclusion” of your experiment.
It shows a detailed understanding of the scientific principals involved and uses correct science vocabulary.
The reasoning should usually be at leas t 2-3 sentences in length.

9. CER Example 1: Aliens

10. On Your White Board: CER Box-Chart
Question: Is her dad an alien?
Claim (What’s your answer to the question asked?):
Yes he is. or
No he is not an alien.
Evidence: What evidence did she provide?
Reasoning: Write a sentence or two explaining why she thinks her claim is true, provide evidence.

12. On Your White Board: Mars Curiosity Rover
Question: What question is trying to be answered?
Claim:
1.No life was on Mars.
2.There was life on Mars.
Evidence What evidence is being collected to answer the question?

14. Last example on your white board
Read the scenario below, look at the data given in the table, and answer the prompt.
Here’s some help to get started: What are the possible questions that could be asked?
1. Running a mile does not have an effect on the student’s cardiovascular system.
2. Running a mile does have an effect on the student’s cardiovascular system.
What is your evidence to support your claim.

16. Here’s a guide to grade how you did.

17. Homework: Due when you walk in on Wednesday/Thursday
