AST 101: INTRODUCTION TO ASTRONOMY: STARS AND GALAXIES

Syllabus: Fall 2015
 
 

Course Description and Prerequisites :

This is a lower division course organized around three questions: Why does the Sun shine? How stars end their life? How did the structures we see in the Universe today (stars, planets, galaxies...) form? How did the Universe begin and what is its fate? We will discuss what astronomers know today about the answers to each of these questions. More broadly, I hope to convince you that, via a combination of careful observation and theory, science allows us to confidently answer at least some questions that lie far outside the realm of what we experience in everyday life.

This course does not require SBU course prerequisites.

Course Requirements and Grading Policy
:

Grading:

10% clicker questions
20% written quizzes
40% three in-class midterms
30% comprehensive final exam

Clicker Questions:

A few times during each class I will ask questions to get you to think carefully about some of the concepts we have covered. Often I will have you talk to your neighbors before answering, so you can help each other figure out the correct answer. 

Use of clickers:

*      Improves your grade.  When you discuss and debate with others your knowledge improves.

*      Gives YOU immediate feedback regarding what you do and do not understand.

*      Tells ME what the class does not understand.

*      Greatly improves class participation.

Points will be assigned as follows:
