ASTRONOMY II

The Sun and Stars

In an effort to understand the Sun and stars, class work will start off with an in-depth investigation into the nature and properties of light.   Following the light investigations students will explore the history of nuclear reactions (fission and fusion) in an effort to understand the energy source for stars.     After examining the life of a stars,  students will explore a bit about star clusters, Galaxies and other objects in deep space.
