  1. 1. Strengthening Scientific Explanations<br />
  2. 2.
  3. 3. Claim<br />The claim makes an assertion or conclusion<br />that addresses the original question or<br />problem about a phenomenon.<br />
  4. 4. Evidence<br />The evidence supports the student’s claim<br />using scientific data. This data can come<br />from an investigation that students complete<br />or from another source, such as<br />observations, reading material, or archived<br />data, and needs to be both appropriate and<br />sufficient to support the claim.<br />
  5. 5. Reasoning<br />The reasoning links the claim and evidence<br />and shows why the data count as evidence<br />to supportthe claim. Often in order to make<br />this link, students must apply appropriate<br />scientific principles. <br />
