Research can also be done. CERs are a form of Scientific arguments share what we learned & answer the Question! scientific argumentation! Free Recall Slide! Write everything you can remember! Why write using CER? In science, we never say that something has been proven. Instead scientists write arguments that use evidence to show support for their answer. A CER response organizes your argument, either in a paragraph or a full report. Formatting a CER Free Recall Slide! Write everything you can remember!  Claim A claim is a statement that answers the question. A claim: Should JUST answer the question Should restate the question for clarity Usually only be one sentence Does not include any explanation, reasoning, or evidence If you start to write “because…” you have gone too far. Ex: Students who eat breakfast perform better on exams. Free Recall Slide! Write everything you can remember!  Evidence The evidence is the info used to support the claim. In a CER, we describe the evidence factually for an audience who may not have seen it for themselves. Examples of evidence include: Observations Facts you’ve read Lab Data/Results Ex: Scientists found that the mammalian brain depends on glucose as its main source of energy. Free Recall Slide! Write everything you can remember!  Reasoning The reasoning is the explanation of “why and how” the evidence supports the claim. Reasoning: Explains why this evidence is important to this claim? Connects the evidence (result) to science concept(s) Ex: This demonstrates that the human brain can only metabolize glucose and breakfast foods provide an immediate supply of energy for the brain, literally improving brain power. Free Recall Slide! Write everything you can remember!  Activity: Components of CER With your table partner, read the following statements and determine if they are a claim, evidence or reasoning statement: 1. Adding 1 ice cube to 50 mL of water will not stop the water from boiling. 2. This picture is evidence that shows whether or not the water stopped boiling or continued boiling when the ice cube was dropped inside. It shows the water stopped boiling once the ice cube was added. 3. My data doesn’t support my claim because my claim said the water would keep boiling, but my data shows that the water stops boiling after putting the ice cube in. 4. According to data acquired by NASA, burning fossil fuels releases carbon dioxide, methane, and particles into the air. 5. As I read the data and talked to my friends, it seems like cellphones are bad for your health. Free Recall Slide!

Step 2 Brainstorm Evidence & Identify the Science Concepts Step 3 Write your response Step 4 Revise your response Step 1 Annotate the guiding question. Underline the keywords Annotate these keywords Rewrite the question in your own words *Make sure that you understand the question so you can answer it properly  Annotate this Guiding Question: What happened to the island on Titan? Remember: Underline the keywords Annotate these keywords Rewrite the question in your own words  Annotate this Guiding Question: This is the object that is changing. Maybe I should rewatch the video to understand. What happened to the island on Titan? This is where this change is I’m focusing on something changing, happening. Maybe I should do some maybe cause and effect. research on Titan. Remember: Underline the keywords Annotate these keywords Rewrite the question in your own words  Rewrite the Guiding Question: What happened to the island on Titan? What is causing the disappearance of the island on Titan? Remember: Use your previous annotations to make the question easier to understand for you. Free Recall Slide!

Consider: What text evidence do you What words have we been know? using throughout this unit? What lab evidence do you We want to include these have? words in our writing Observations Quantitative Data Free Recall Slide! Write everything you can remember!  Step 3 Write your response. Identify the claim, evidence, reasoning, and conclusion in this CER. The disappearing island on Titan is caused by the amount of rainfall on the surface. Planetary scientist Shannon MacKenzie observed that Titan has a 30 year rain cycle, and that the moon has seasons just like Earth. This would support the idea that at certain points of the cycle, there can be enough rainfall to overfill the lakes. This does happen on Earth in areas with lots of rainfall. According to the John Hopkins Applied Physics Laboratory, “Titan is the only moon in our solar system with a dense atmosphere, which supports an Earth-like cycle of ethane and methane clouds, rain, and liquid that flows into lakes and seas.” This rain cycle can cause the rise in lake levels on Titan’s surface, which would covers the island from view. With this evidence, we can conclude that the islands have disappeared due to the increased rainfall on Titan.  Step 3 Write your response. The disappearing island on Titan is caused by the amount of rainfall on the surface. Planetary scientist Shannon MacKenzie Color Key observed that Titan has a 30 year rain cycle, and that the moon has seasons just like Earth. This would support the idea that at Claim certain points of the cycle, there can be enough rainfall to overfill Evidence the lakes. This does happen on Earth in areas with lots of rainfall. According to the John Hopkins Applied Physics Laboratory, “Titan Reasoning is the only moon in our solar system with a dense atmosphere, Conclusion which supports an Earth-like cycle of ethane and methane clouds, rain, and liquid that flows into lakes and seas.” This rain cycle can cause the rise in lake levels on Titan’s surface, which would covers the island from view. With this evidence, we can conclude that the islands have disappeared due to the increased rainfall on Titan.  Step 3 Write your response. Most CERs follow this format: For each piece of Claim: evidence, provide your Evidence #1: reasoning and connect Reasoning for evidence #1: it back to your claim. Evidence #2: You can have more than Reasoning for evidence #2: 1 piece of evidence to Evidence #3: support your claim. The Reasoning for evidence #3 more evidence = the Conclusion: stronger the claim  Sentence Frames To Describe Evidence: To Describe Reasoning: The evidence that supports If ____, then … my claim is … This is important because … The evidence that refutes Since … other claims is … Based on the evidence …. My first piece of evidence is … This claim is stronger because … Another piece of evidence is… This claim is weaker because … Scientists found … Based on the evidence, I The results show... conclude that... Free Recall Slide! Write everything you can remember!  Step 4 Revise your response Reread your paragraph out loud! Did you know that you catch more errors when you read aloud? Consider: Does the paragraph flow? Do the sentences make sense as a whole? Do you need to add transitions between sentences? Can you simplify your ideas to make them stronger? Ask a peer or teacher to review your response if you are not sure. They may see mistakes you missed or offer help when needed. Free Recall Slide!
