C.E.R.C. Essay Claim ~ Evidence ~ Reasoning ~ Conclusion Connections that yield Conclusions to Questions

QUESTION: The scientific problem you are trying to answer The scientific problem that drives all investigations and learning Think about what you are trying to learn and understand Consider the variables you are learning more about What are you studying? What is the research/experiment about?

CLAIM: The statement or conclusion that answers the original question/problem Consider the observations you already have Consider the experimental and book research Re-consider the variables and their relationship to each other This is like your hypothesis ~ based on the available evidence

Question & Claim Example: Who killed a recently divorced woman who was found murdered in her home? The woman’s ex-husband killed her.
