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.
