Activity Overview

Students will use a graphing calculator to find a regression equation and then interpolate the data from the equation using integration. They will explore the length of day during the winter and summer solstice at various locations.

Before the Activity

See the attached Activity PDF file(s) for detailed instructions for this activity.

During the Activity

Follow the procedures outlined in the Activity.

Students will:

  • Determine the regression equation that best fits a set of data and interpolate through integration of this function.
  • After the Activity

    Review student answers:

  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
