## Greenhouse Gas Emissions

#### Activity Overview

In this activity, students analyze statistical data using the calculator and the TI InterActive!™ software. They use linear regression to study the increase in levels of carbon dioxide emission over the years.

#### Before the Activity

• Download the TI Connect™ software to transfer data from the computer to the calculator
• Link the TI Connect to the calculator
• Install the TI InterActive! on the computer
• Print pages 1 - 2 from the attached PDF file for the class
• #### During the Activity

Distribute the printed pages to the class.

Follow the Activity procedures:

• Download the data table into the data editor
• Name the lists and copy the list tables into a document
• Export the data from the computer to the calculator
• Plot a graph of Carbon Dioxide Emissions versus Number of Years
• Perform a linear regression [on the calculator or on TI InterActive] and find a line of best fit
• Use the graph editor to include the best fit line on the graph
• Graph the CO2 emissions per capita by year
• Plot a graph of CO2 emissions per unit of GDP
• Based on the regression curve, answer questions listed on the activity pages
• #### After the Activity

Review student results:

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