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.
