Climate Change

The Earth has been getting warmer. In this lesson, students will explore the history of Earth’s atmosphere, discover why it’s changing, and show how current trends may impact the future.

1

Uncover the patterns of change.

Read Chapter 41, Section 1 of E. O. Wilson’s Life on Earth to understand the complexities of climate change. See how it has affected natural resources, and learn about the impact this could have on our future.

Trace the history of Earth's climate.

In the Click and Learn app, tap through “Paleoclimate: A History of Change” to see how two factors that affect Earth’s climate — solar radiation and the composition of atmosphere — have been tracked over millions of years. Then zoom into the Modern View of the EarthViewer app to get an interactive look at the changes in the atmosphere’s temperature from 1912 to 2012.

3

Chart the changes.

With the RWT Timeline app, create an interactive timeline about climate change for others to learn from. The timeline should show natural and human-caused events that have led to the rise of carbon dioxide levels in Earth’s atmosphere during the past 100 years. Use the information you’ve learned from ”Paleoclimate: A History of Change,” EarthViewer, and Life on Earth to include trends in global temperature. And, remember to use simple, non-scientific language that anyone can understand.
