Astronomy Final Exam Information

THE EXAM

The exam will be on Quia and will consist of multiple choice, true/false, fill in the blank, odd-one-out and essay questions. 

Your study guide may be used as notes on the exam

You will have only 1 chance to take the exam.

                        Example of an “Odd-One Out” Question:

        Q:  Which one does not belong?   Spring Winter Tuesday Summer

        A:  Tuesday is the odd one out because it is a day and spring, winter, and summer are seasons

Essay questions are answered with a paragraph that starts with a topic sentence, answers the question accurately, and provides scientific details and
examples as support.Examples of essay questions: 

1.       In Main Sequence stars, what is the relationship between brightness and temperature?

2.       Explain why we see different constellations in the night sky at different times of year.

3.       How can scientists learn about our universe’s past simply by looking through telescopes?

4.       Explain, in detail, an astronomical current event that occurred during this semester.

5.       Identify and describe the significance of two of the major players in the history of astronomy.

6.       Describe the organization of our universe from large to small, including at least 5 astronomical terms discussed in class.

7.       What is the importance of constellations: why do humans map the sky?

8.       Identify and describe in detail the two major pieces of evidence that support the theory of the Big Bang.

9.       Describe the full life cycle of our sun, including all major stages of its life.

10.    Draw and label a diagram of the major stages of life of stars, including low and high mass stars.

11.    Why is a Red Giant red in color?

12.    What is nuclear fusion?

13.    Why is it sometimes said that humans are “made of stardust”?

14.    What would happen to a human who tried to travel into a Black Hole?

15.    If we cannot see them, how do we locate black holes in our universe? Include a diagram.

16.    Why does the sun shine?          

 

THE PRACTICE EXAM

http://www.quia.com/quiz/1819873.html

A practice exam is available on Quia now through the start of the exam. It consists of randomly selected questions from a bank of possible exam questions.  It is a graded assignment and is required to take at least once, however you are highly encouraged to take the practice exam as many times as you can.  The more you take the practice exam, the more possible exam questions you will see.


Other Resources

You have several resources to use as you review for our exam including class notes, handouts, class activities and discussions, homework assignments, the class webpage (www.zbscience.com), the practice test on Quia and the internet (I highly suggest www.astronomynotes.com).


THE STUDY GUIDE

The study guide is not graded and is optional but highly encouraged since you may use the study guide on the final exam as your notes. See the link to the study guide at the bottom of this page.
