SEP-7 Engaging in Argument from Evidence

(C) Claim: About phenomenon or about the results of an investigation

• • A claim is a statement that answers the question. It will usually only be one sentence in length. The claim does not include any explanation, reasoning, or evidence.

  • What can you conclude?

  • It should describe the relationship between dependent and independent variables.

(E) Evidence: Data used to support the claim

• The evidence is the data used to support the claim. It can be either quantitative or qualitative depending on the question and/or lab. 

  • Sufficient—Use enough evidence to support the claim.

  • Appropriate—Use data that support your claim. 

  • Qualitative, Quantitative, or a combination of both.

(R) Reasoning: Ties together the claim and the evidence

• An explanation of “why and how” the evidence supports the claim. It should include an explanation of the underlying science concept that produced the evidence or data.

  • Shows how or why the data count as evidence to support the claim.

  • Provides the justification for why this evidence is important to this claim.

  • Includes one or more scientific principles that are important to the claim and evidence.
