Lesson 1: Is the Earth's Climate Changing?


The main purpose of this lesson is to introduce the concept of climate change and to reexamine the earth as an energy system. The lesson begins by students watching short video clips with different perspectives on global climate change. The class then discusses whether or not they believe the climate is changing and what would count as evidence of climate change. Finally, the class analyzes temperature data from the past 120 years and then the past 1000 years that illustrates how the climate has become warmer over time. In the next lesson, students will explore why that climate change is occurring.
