 Unit 1:  Scientific Thinking in Experimental SettingsInstructional GoalsData CollectionSelect appropriate measuring devices.Consider accuracy of measuring device and significant figures.Collect data for the widest reasonable range of independent variable values. Use metirc units (SI), conversions, prefixes.   Experimental Design Identify and classify experimental variables as independent, dependent, or controlled. Make qualitative predictions about the relationship between variables.Record the procedure used to gather data from the apparatus.Construct and label a data table. Mathematical ModelingUse Logger Pro software to perform graphical analysis of data.Make test plots of data to find linear relationships.Write mathematical representations, in standard y = mx + b form, for linearized data. Replace y and x with dependent and independent variable names Replace m and b with constants including units and provide interpretations for the physical significance of the slope and y-intercept.Relate mathematical and graphical expressionsUse proportional reasoning in problem solving. Unit 1 - Instructional Goals1.   Demonstrate proper use of measurement devices, and record the value in a manner consistent with the limit of precision of the tool being used to measure.2.  Recognize that instruments have a limit to their precision.  Relate the data recorded to the quality of the measurementOnline Practice #1 Online Practice #2 ` `Online Practice #3    Online Practice #4TutorialsUnderstanding Conversion Factors Dimensional Analysis (Conversions)  Documents  Vernier Graphical Analysis Instructions Doing Science Metric Conversions (KHDBdcm) Unit 1 Metric Conversion Unit 1: Scale Reading, Uncertainty, and Sig Figs Unit 1 WS2: Reading Scales Unit 1 WS 6: Dimensional Analysis
