 # Lesson Plan: Teaching Linear Regression using Arctic Sea Ice Data

As a high school or undergraduate Mathematics teacher, you can use this set of computer-based tools to help you in teaching introductory statistics and specifically linear regression.

This lesson plan will allow you to teach introductory statistics through linear regression assignments. The lesson plan includes a hands-on computer-based classroom activity to be conducted on datasets of Arctic Ice Data (1979-2017). This activity includes a set of inquiry-based questions that will enable your students to apply their understanding of scatter plots, regression equations, correlation coefficients, regression lines, and linear regression with residual (outlier) plots.

Thus, the use of this lesson plan allows you to integrate the teaching of a climate science topic with a core topic in Mathematics.  Questions

1. Use an example to describe linear regression analysis.
2. Is the extent of the Arctic Sea Ice decreasing since 1979?
3. Has the monthly extent of Arctic Sea Ice changed from 1979- 2017?
4. Discuss the Ice Albedo Feedback and Global Warming to explain the differences in extent of Arctic Sea Ice over the past four decades.
