Learn about volcanic ash and watch a visualization of the Calbuco volcano to see how ash travels around the world. 

Students use scale to determine the area of volcanic deposits following the March 3, 2015 eruption of Chile's Mount Villarrica stratovolcano, one of the country's most active volcanoes.

Students will describe the changes in a newly-formed volcanic island over the first three years of its life.  

Students explore albedo, sea ice, and the relationship between changing albedo and changing sea ice using data visualizations. 

Students develop and test a hypothesis about how albedo affects temperature.

Students observe the surface temperatures of a variety of surface types found in a suburban environment.

In this activity, students make a claim about the cause of ocean currents and then develop a model to explain the role of temperature and density in deep ocean currents.  This lesson is modified from "Visit to an Ocean Planet" Caltech and NASA/Jet Propulsion Laboratory.

In this experiment, students make a claim about the cause of ocean currents and then develop a model to explain the role of salinity and density in deep ocean currents.  This lesson is modified from "Visit to an Ocean Planet" Caltech and NASA/Jet Propulsion Laboratory.

Use the Earth System Data Explorer to analyze data and make a claim about which 2018 eruption was larger, Kilauea, HI or Ambae Island, Vanuatu.

Students watch a video introducing the concept of albedo and answer questions.
