**Unit 1: Scientific Thinking in Experimental Settings**

Instructional Goals

**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.

**Data
Collection**

Select 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.

**Mathematical
Modeling**

Use 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.
