Lakes are changing worldwide due to altered climate. Many lakes that were historically frozen in the winter are now experiencing fewer days of ice cover and earlier ice-off dates. In this module, students will explore long-term ice-off datasets from several lakes and use linear regression to make predictions about ice-off dates in the future. Project EDDIE modules are designed with an A-B-C structure to make them flexible and adaptable to a range of student levels and course structures.

This entire module can be completed in one 2-3 hour lab period or two 50 minute lecture periods for introductory or intermediate level students. Activities A and B could be completed with upper level students in one 50-60 minute lecture period. Students will need 1-2 hours outside of class to prepare for the exercise and complete the homework activities.
This module has been used in a non-majors Environmental Science course (Part A) and several Freshwater Ecology and limnology courses (Parts A and B for lower-level courses; Parts A, B, and C for upper-level courses). We anticipate the module could be used in a variety of courses. Module materials can be tailored to increase or decrease the background information depending on students' quantitative skills.
