Question

1. which three questions should scientists ask when they evaluate the claims of other scientists?

how many times was the investigation repeated?
do the scientists work for a major university?
did the scientists use the latest computer tools to analyze data?
were all the variables but one controlled?
how big was the sample size?

1. which two things should scientists consider when evaluating a scientific claim?

whether the evidence is collected from a trustworthy source
if there is enough proof to support the claim
the personal interests or opinions of the researcher

1. what does the term evaluate mean?

a. to make an uneducated guess
b. to make a careful judgment about something
c. to accept something without question
d. to ignore evidence and make a conclusion

1. what is the process that scientists use to communicate their findings and conclusions?

a. research - data - conclusion
b. claim - evidence - opinion
c. claim - evidence - reasoning
d. claim - research - data

1. what is the purpose of collecting evidence in the claim - evidence - reasoning process?

a. to assure the claim is true
b. to disprove the claim
c. to support or contradict the claim
d. to generate new ideas for the claim

Explanation:

1. Repeating an investigation, controlling variables, and sample - size are important for scientific evaluation. Working at a university and using the latest computer tools are less crucial for the core evaluation of a scientific claim.
2. Trustworthy evidence sources and sufficient proof are key when evaluating a scientific claim. Personal interests of researchers are biases to be avoided.
3. 'Evaluate' means to make a careful judgment, not an uneducated guess, acceptance without question, or ignoring evidence.
4. Scientists use the claim - evidence - reasoning process to communicate findings. It's about presenting a claim, supporting it with evidence, and explaining the reasoning.
5. The purpose of collecting evidence in the claim - evidence - reasoning process is to support or contradict the claim, not just to assure it's true or generate new ideas.

Answer:

1. How many times was the investigation repeated?; Were all the variables but one controlled?; How big was the sample size?
2. whether the evidence is collected from a trustworthy source; if there is enough proof to support the claim
3. B. to make a careful judgment about something
4. C. claim - evidence - reasoning
5. C. to support or contradict the claim
