Solar Activity

Another in a series of experimental internet based lessons

Introduction:

Below are listed several theories related to solar activity for you to explore:

• The sun is a flawless smooth round ball of fire.
• Sunspots are permanent features of the sun which never change.
• The sun does not rotate; but rather, remains stationary in space.
• Sunspots occur in a regular and predictable cycle/pattern.
• The sun gives off only one type of radiation.
• A solar eclipse happens when either the earth or the moon casts a shadow on the sun.

Your task:

Select two of the theories above to investigate. At the bottom of this web page is a list of internet address links for you to explore in attempting to prove or disprove your selected theories. You may also use any text based references that you might have available.

You will need to write a paper (using a word processor or desk top publishing program) to describe your findings, cite your sources, and clearly explain your conclusion. You may want to include images with structures marked for several theories.

Be as complete as possible in your explanation.
