In this activity students will examine NASA data to determine the differences between a solar and lunar eclipse.

NASA makes observations and collects data about ozone in the Great Lakes region. Read about the research and analyze related data.

This hands-on activity is the construction of an extended coverage area of eclipse glasses to provide extra protection for safely viewing a solar eclipse. This makes it harder to look outside the lenses on the eclipse glasses.

In this activity, students will model the geometry of solar eclipses using quarters to represent the Sun and Moon (not to scale).

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.

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

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

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.

Watch NASA videos about aerosols and volcanic ash.
