In this lesson, students investigate whether other parts of the world are changing and getting hotter just like Colorado.

The goal of this module is to explore some of the factors that might be associated with an individual's level of concern about the environment and global warming. Crosstabulations, frequency distributions, and bar charts will be used.

NASA scientists, using several NASA Earth observing satellites, continue to seek answers to questions related to climate change. Several of those questions, focused on such topics as the effect of clouds and aerosols, and the role of the sun's cycles and the carbon cycle, are included in this article. Images of the respective satellites involved in the research are shown. This article is part of the Climate Kids website, a NASA education resource featuring articles, videos, images and games focused on the science of climate change.

The forests of North America have seen plenty of change in a pretty short period of time, at least geologically speaking. Up until about 18,000 years ago, the Laurentide Ice Sheet covered Canada and much of the eastern United States. When temperatures climbed and the ice sheet retreated, forests gradually reemerged. But how? Did pockets of trees find refuge in sheltered areas during the Ice Age? Or were all tree species pushed to the southern tier of the United States, only to spread north again after the ice disappeared? Scientists still debate the topic, but one thing is clear: today’s forests in the eastern United States bear little resemblance to post-glacial forests. Starting with European colonial settlers and marching through four centuries of development, drought, and fire, the tree cover of North America became fragmented.

Students explore the greenhouse effect in this lesson using a computer simulation and develop a model for how it works.

In this lesson, students explore how human activities will continue to impact Antarctic ice, discuss human contributions to climate change, and investigate what we can do to stop/reverse these negative effects.

This lesson explores if it is normal that world temperatures are rising at the currently observed fast pace.

How does energy flow in and out of our atmosphere? Explore how solar and infrared radiation enters and exits the atmosphere with an interactive model. Control the amounts of carbon dioxide and clouds present in the model and learn how these factors can influence global temperature. Record results using snapshots of the model in the virtual lab notebook where you can annotate your observations.

Today's science standards encourage inquiry based activities and the best inquiry based activities result when an scientist and teacher collaborate. This activity was created by Dr. Alex Hastings, one of the scientists who helped discover Titanoboa, a large snake that existed 60 million years ago in South America. In this activity students will use the measurement of a Titanoboa vertebrae to estimate the size of the snake and the temperature that must have existed back then to allow the snake to get to such a large size.

In this lesson, students utilize case studies to learn about the ways climate change is currently impacting people and other living things around the world.

In this lesson, students explore reasons why temperatures in particular Colorado cities are rising.

This lesson explores climate data at local, national, and global levels to determine that temperatures are changing all over the world, and that there are certain locations where temperatures are warming faster than the global average.

This lesson introduces why certain cities in Colorado are getting hotter using a video by the Denver Post that describes the pattern.

During this lesson, students explore the increase in summer temperatures and describe the pattern as it relates to Colorado using a video by the Denver Post.

This lesson has students investigate how albedo is contributing to temperature increasing in some places, like cities, are increasing at faster rates than elsewhere.

This lesson has students explore what land use changes are happening and how changes in surface color affects temperatures in cities.
