We Need a Faster Fan (Math)

Introduction

If the students are participating in the lesson "Is Wind Energy the Answer?" they will have a completed data sheet measuring the volt output from their three different blade designs, at 4, 6 and 8 mph. If the class is blended, or not all students have data sheets, have the students work in pairs or groups.

  • Students will graph the data from their data sheet on paper, and on the stat plot function of a graphing calculator.
  • Students will estimate a line of best fit on paper, and estimate the volts at 11 mph and 40 mph.
  • Students will perform a linear regression on their data on the graphing calculator and use it to predict the volts at 11 mph and 40 mph.
  • Students will compare their paper estimates to their graphing calculator predictions and analyze the accuracy of their paper estimates.
