Assessing Evidence Quality
Assessing Evidence Quality is a Grade 7 science concept from Amplify Science (California) Chapter 3: Analyzing New Evidence, teaching students to evaluate both the quality and relevance of scientific data. Before using data to support a claim about Mars geology, scientists must determine if the evidence is reliable, precise, and directly addresses the investigation at hand.
Key Concepts
Not all evidence is created equal. Before using data to support a claim, scientists must evaluate its quality . High quality evidence is clear, precise, and comes from a reliable source.
They must also judge the relevance of the data. A clear image of a crater is interesting, but it is irrelevant if the question is about a river channel. Scientists must be disciplined, filtering out noise to focus only on data that directly addresses the investigation at hand.
Common Questions
What makes evidence high quality in science?
High-quality evidence is clear, precise, and from a reliable source. It should be based on systematic observation or measurement rather than casual or anecdotal reports.
What is the difference between evidence quality and evidence relevance?
Quality refers to how reliable and precise the data is. Relevance refers to whether the data actually addresses the specific question being investigated. Evidence can be high quality but irrelevant if it does not speak to the claim at hand.
Why do scientists filter out irrelevant data?
Including irrelevant data can muddy analysis and lead to incorrect conclusions. Scientists must be disciplined in selecting only data that directly addresses their specific claim, even if other interesting data is available.
What do Grade 7 students learn about evidence quality in Amplify Science Chapter 3?
In Chapter 3 of Amplify Science California Grade 7, students analyze Mars satellite data and practice evaluating both the quality and relevance of evidence, learning to filter observations to include only data that directly supports or refutes the geological claim being investigated.
