Unit 1: Scientific Thinking in Experimental Settings
Instructional GoalsExperimental 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
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.
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.
