Below are sample questions representative of the exercises included on this worksheet and related 7.14 Evaluating Source Credibility in Science skill assessments:

Problem 1Difficulty: Mastery

A student claims: “The most credible source for a scientific claim usually explains methods and provides evidence, not just conclusions.” Which source best supports this claim?

AA short opinion editorial that argues for a conclusion without data.

BA poster slogan that says ‘Science proves it!’ with no evidence.

CA peer-reviewed research article that includes a methods section, results with data, and a discussion of limitations.

DA social media post that states a conclusion with no details.

Solution & Explanation:Peer-reviewed research articles show how the conclusion was reached by describing methods, presenting results, and noting limitations. Conclusions without evidence are not as trustworthy.

Problem 2Difficulty: Mastery

AA video showing one test without describing the procedure.

BA company press release saying the new material is ‘non-toxic.’

CA standardized safety testing document (from a standards organization) describing the exact test procedure and how to compare materials fairly.
