Seventh Grade Science
Name: ______________________________
| 7.1.1 | Recognize and explain that when similar investigations give different results, the scientific challenge is to judge whether the differences are trivial or significant, which often takes further studies to decide. |
| 7.1.2 | Explain that what people expect to observe often affects what they actually do observe and provide an example of a solution to this problem. |
| 7.1.3 | Explain why it is important in science to keep honest, clear, and accurate records. |
| 7.1.4 | Describe that different explanations can be given for the same evidence, and it is not always possible to tell which one is correct without further inquiry. |
| 7.2.3 | Decide what degree of precision is adequate, based on the degree of precision of the original data, and round off the result of calculator operations to significant figures* that reasonably reflect those of the inputs. |
| 7.2.6 | Read analog and digital meters on instruments used to make direct measurements of length, volume, weight, elapsed time, rates, or temperatures, and choose appropriate units. |
| 7.2.7 | Incorporate circle charts, bar and line graphs, diagrams, scatter plots*, and symbols into writing, such as lab or research reports, to serve as evidence for claims and/or conclusions. |
| 7.5.3 | Demonstrate how the scale chosen for a graph or drawing determines its interpretation. |
