Information

This curriculum module contains interactive MATLAB® live scripts that explore the Nenana Ice Classic data set of ice breakup times from 1917 - 2021.

The Nenana Ice Classic is an annual event that takes place in Nenana, Alaska. It is a guessing game where people try to predict the exact time when the ice on the Tanana River will break up in the spring. Participants purchase tickets for a small fee and guess the month, day, hour, and minute when the tripod, which is placed on the frozen river, will move and stop the clock. The tripod is connected to a wire that is attached to a clock on the riverbank. When the ice starts to melt, the tripod moves with the current, and when it falls through the ice, the wire pulls a rope that stops the clock. You can find the exact dates and times of ice breakup have been collected since 2017 and reported on a calendar in the Nenana Ice Classic Brochure on the Nenana Ice Classic Website.

You can use these live scripts as demonstrations in lectures, class activities, or interactive assignments outside class. This module covers the engineering design process, mathematical modeling, fitting data to a linear model, and data analysis.

The instructions inside the live scripts will guide you through the exercises and activities. Get started with each live script by running it one section at a time. To stop running the script or a section midway (for example, when an animation is in progress), use the image_1.png Stop button in the RUN section of the Live Editor tab in the MATLAB Toolstrip.

Prerequisites

This module assumes knowledge of

  • linear functions – graphing, writing equations, and slope.
  • representing data as a table and scatter plot.
  • modeling of an approximately linear situation with a line of fit.
