Experimental Design

  • Identify and classify experimental variables as independent, dependent or controlled.
  • Make qualitative (non-mathematical) 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 metric units, conversions and prefixes.

Mathematical Modeling

  • Use Desmos to perform graphical analysis of data.
  • 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 expressions.
  • Use proportional reasoning in problem solving.
