In this video Dr. Richard Alley poses and addresses a simple question: What does carbon dioxide have to do with global warming?

This static image from NOAA's Pacific Marine Environmental Laboratory Carbon Program offers a visually compelling and scientifically sound image of the sea water carbonate chemistry process that leads to ocean acidification and impedes calcification.

In this activity, students act as water molecules and travel through parts of the water cycle (ocean, atmosphere, clouds, glaciers, snow, rivers, lakes, ground, aquifer). Students use a diagram of the hydrologic cycle to draw the pathway they traveled.

This activity addresses naturally occurring climate change involving ENSO (El-NiÃo Southern Oscillation). In this activity, students play the role of a policy maker in Peru. First, they determine what sort of ENSO variation is occurring. Then, they must decide how to allocate Peru's resources to manage for possible weather-related problems.

This visualization explains in simple and easy-to-understand visuals the causes of sea-level change.

This online quiz tests knowledge about climate change, its impacts, how we know about earth's climate, and potential solutions.

This activity is a hands-on guided inquiry activity designed to highlight the role of an ice shelf on slowing the movement of continental ice sheets in Antarctica. Students build a model of Antarctica and both continental glaciers and ice shelves using paper models of the land and slime for glaciers and ice. Students use their model to explore the impact of recent and potential ice shelf melting and break-up.

In this resource, students watch a 2-minute video explaining albedo. The video shows visualizations of albedo across Earth and how it can change. Students will interpret the images in the video and answer questions about albedo.

This video provides a good overview of ice-albedo feedback. Albedo-Climate feedback is a positive feedback that builds student understanding of climate change.

This activity introduces the concept of weather. Students follow the first stages of the scientific process to investigate the four factors that contribute to making weather what it is.

In this interactive activity students will create a very simple climate model. They use worksheets, chips/tokens, and follow rules for heat exchange. The activity only models temperature but there are instructions for adaptations of the model, such as rule changes for an atmosphere with increased levels of CO2.

In this activity students build a model of a watershed to learn where water goes when it rains. Students then make predictions and draw what they observe.

This infographic provides an overview of what coral bleaching is and its causes. The resource combines short summaries of the steps of coral bleaching with more in-depth (though still succinct) explanations for what is happening to cause the coral to appear white. A short list of causes for coral bleaching is also provided.

This is a series of 5 guided-inquiry activities that examine data and models that climate scientists use to attempt to answer the question of Earth's future climate.

Students consider why the observed atmospheric CO2 increase rate is only ~60% of the CO2 loading rate due to fossil fuel combustion. They develop a box-model to simulate the atmospheric CO2 increase during the industrial era and compare it to the historic observations of atmospheric CO2 concentrations. The model is then used to forecast future concentrations of atmospheric CO2 during the next century.

Students act out 4 different molecules (nitrogen, oxygen, carbon dioxide and water vapor) to discover which ones are greenhouse gases and which ones are not.

This activity utilizes a PhET greenhouse gas simulation to explore the interaction of different atmospheric gases with different types of radiation.

This animation starts with a schematic illustration of glacier growth and then introduces six different methods that researchers use when studying ice cores in order to deduce the climate of the past. The research methods that are briefly introduced are ice layering, pollen, oxygen isotopes, ice crystals and gases trapped inside, and other chemistry.

This activity allows students to explore sea level rise. The experiment allows them to test whether land ice and/or sea ice contribute to sea level rise as they melt.

This classroom resource is a combination of 3 visualizations and accompanying text that illustrate how 3 key natural phenomena - cyclical changes in solar energy output, major volcanic eruptions over the last century, and El Nino/Nina cycles - are insufficient to explain recent global warming.
