Students model Earth's tectonic plate movement and explore the relationship between these movements and different types of volcanoes.

In this NASA-JPL lesson, students create a model of a volcano, produce and record lava flows, and interpret geologic history through volcano formation and excavation. 

Compare pictures of different volcanoes. Then visit NASA's Space Place to learn about volcanoes and answer questions about volcanic eruptions.

Students will review the NASA Space Place video, "Tectonic Forces", and answer questions about tectonic plates.

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

This mini-lesson features time-series graphs of mean salinity at the surface for the Arctic and Antarctic regions. A series of questions guides students in their analysis.

In this mini lesson, students use in-water profiles of historical ocean data to analyze how sea surface salinity varies with depth. 

This NASA visualization shows sea surface salinity observations (September 2011-September 2014). Students review the video and answer questions.

Watch NASA videos about aerosols and volcanic ash.

Exploring salinity patterns is a great way to better understand the relationships between the water cycle, ocean circulation, and climate. In this mini lesson, students analyze sea surface salinity mapped plots created from the Earth System Data Explorer, paired with questions (and answers) from the Aquarius Mission.
