Claim Evidence Reasoning in Chemistry Explained

The video tutorial by Christy, a middle school science teacher, guides viewers through writing a scientific explanation using the claim, evidence, and reasoning format. It covers identifying the question, analyzing data, and using evidence and reasoning to support a claim. The tutorial also includes writing a complete scientific explanation and conducting a self-assessment. Additional resources are provided for further practice.

What is the purpose of the reasoning section in the scientific explanation?

• To state the question

• To describe the experiment setup

• To explain why the evidence supports the claim

• To list the materials used

What should you do after combining the claim, evidence, and reasoning into one paragraph?

• Add more data

• Read through the paragraph to ensure it flows well

• Change the experiment

What is the final step in the self-assessment process?

• Checking for spelling errors and grammar

• Adding more evidence

• Rewriting the claim

• Changing the question
