Do Forest Fires or Cars Produce More CO2 Emissions? High School Activity
Published on December 13, 2024
Students act as environmental engineers to solve a problem using carbon dioxide (CO2) emissions from cars and wildfires. Wildfires are a timely topic because every year they cause people in many areas to face poor air quality. Students use Microsoft Excel to investigate CO2 emitted from two sources: highway traffic and forest fires. They estimate and graph the CO2 emitted by forest fires and from U.S. highway driving annually from 2004 to 2021. After they analyze these two pieces of data, they analyze a specific fire and evacuation that happened in Saratoga Springs in June 2020, named the Knolls Fire. Finally, using the Excel data and the Knolls Fire data, students decide whether the U.S. should spend money on reducing the number and severity of wildfires, or on reducing CO2 emissions from driving cars. The students design and create a poster based on their decision and present it to the class.
