Earth is made up of five major parts or subsystems: the Atmosphere, Hydrosphere, Biosphere, Cryosphere, and Geosphere. Each major part is connected to the other parts in a complex web of processes.

In this activity, learners will explore an additional tool used to observe the Sun’s atmosphere, called a coronagraph. Learners will create a flipbook of a coronagraph showing a coronal mass ejection.

In this activity, learners predict the likelihood of aurora on Earth by examining the Kp-index and using NOAA’s 30-minute aurora forecast.

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

In this activity, students will compare the methods scientists use to study the Sun, including drawings made during a total solar eclipse in the 1860’s, modern coronagraphs, and advanced imagery gathered by NASA’s Solar Dynamics Observatory.

In this activity students will learn several ways to safely observe a solar eclipse.

In this activity, students will model  the geometry of solar eclipses by plotting a few points on a piece of graph paper, and using quarters and a nickel to represent the Sun and Moon (not to scale). 

In this activity, students will analyze past and future eclipse data and orbital models to determine why we don’t experience eclipses every month.
