Oceans and Atmosphere Example part of CLEAN Collection

This unit allows students to investigate past changes in Earth's climate. Students first explore relationships in climate data such as temperature, solar radiation, carbon dioxide, and ...

Arctic Climate Feedbacks part of CLEAN Collection

This video uses film of the Arctic and Arctic researchers as well as animations to discuss feedbacks in the Arctic climate system related to sea ice, the ocean, and clouds. It explains concepts such ...

Is Climate Change Just a Lot of Hot Air? part of CLEAN Collection

This short video illustrates how warming ocean temperature is a major factor in climate change, particularly the increase in severity of extreme weather (notably storms and drought).

Windy part of CLEAN Collection

This is a full color, worldwide, animated weather map using GIS interface showing current and projected wind and other weather conditions for any location in the world. Data can be viewed at ...

The Buffer Zone: Acid-base Chemistry in the World part of CLEAN Collection

In this activity, students conduct a short hands-on demonstration that simulates ocean acidification resulting from excess atmospheric carbon dioxide and discuss potential implications of increases ...

Climate Variability in the Equatorial Pacific part of CLEAN Collection

In this activity, students work with climate data from the tropical Pacific Ocean to understand how sea-surface temperature and atmospheric pressure affect precipitation in the tropical Pacific in a ...

Climate Variability in the North Atlantic part of CLEAN Collection

In this activity, students examine climate variability in the North Atlantic associated with the North Atlantic Oscillation (NOA) in a case study format.

Predicting Patterns: What Does La Niña Look Like? part of CLEAN Collection

This is an activity designed to allow students who have been exposed to the El Niño-Southern Oscillation to analyze the La Niña mechanism and predict its outcomes in a case study format.

Exploring Patterns: ENSO on the Global Stage part of CLEAN Collection

In this activity, students analyze data maps of sea surface temperature anomalies for a 14-year interval and create an ENSO time line in a case study format. Based on their findings, students ...

El Niño and La Niña Explained part of CLEAN Collection

This short video illustrates the phenomena of El Niño and La Niña: their relationships to tradewinds and surface water temperatures, and their effects on precipitation in North America.
