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

Instructional Goals

**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. **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 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.
