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.
