Today’s Objectives:
Students will be able to…
List and describe the outer parts of the sun.

surface of the sun (6000°C)
The SunGranules – light and dark areas of

sunspots and went blind because of the sun’s harmful radiation waves.
The SunChromosphere – reddish layer above
the photosphere (color layer).
The SunCorona – The outer most layer of the
sun (2 million °C) can only be seen during a solar eclipse.
Time to plot the:Sunspot cycle
