|  This course is for the student who wants to understand some of the basic fundamentals of
astronomy and is curious about the universe in which we live. It is a course which does not require a strong
background in algebra or trigonometry. It is designed for students who need a three credit course in science to meet
graduation requirements.
The course uses an activity-based approach in which students can learn basic laws of
astronomy through a number of hands-on experiments and computer simulations. Students learn to use popular "virtual
astronomy" software packages such as "Voyager Sky Gazer" and "Starry Night" to explore the locations of the planets
and stars during the day or night as seen from any location on earth at any time - past, present, or future. See the
course timetable for details.

TEXTBOOK: The Cosmic
Perspective - 3nd Edition
Authors: Jeffrey Bennett, Megan Donahue, Nicholas Schneider, Mark
Voit
Publisher: Addison Wesley Longman
ISBN# 0-8053-8762-5
Course Objectives:
As a result of this course the student will be able
to:
1. Develop a perspective of our place in the universe including the length and time scale of the universe
and our solar system.
2. Understand key concepts and basic laws of astronomy including the motion of the
planets around the sun,the constellations, how telescopes work, the origin of the solar system, planetary geology
and atmospheres, planetary moons, asteroids, meteorites, comets, properties of our sun, stellar formation, properties
of stars including their size, temperature and luminosity, white stars, neutron stars, and black holes, the galaxies
including the Milky Way, measuring cosmic distances, dark matter, and the big bang theory.
3. Avoid
common misconceptions about astronomy including the causes of seasons, solar and lunar eclipses, light-years, stars
in the daytime, the north star, moon on the horizon, the "dark side" of the moon, phases of the moon, twinkling
stars, black holes, and many more.
Learning
Activities:
Learning activities will include:
- Short quizzes over reading
assignments
- Evening observation of the sky at home and in class (evening course)
- Observation of
important astronomy concepts using laser videodisc, videotape, and CD-ROM instructional media
- Use of
microcomputer based instrumentation to acquire data from experiments such as the variation of luminosity with
distance, refraction of light, spectroscopic analysis of emission spectra from low pressure gases.
-
Designing and simulating a solar system using software such as "Interactive Physics 5.0" and learning about stars,
planets, and constellations using virtual astronomy software such as "Voyager SkyGazer", and "Starry Night"
Grading Policy
Chapter Tests
Tests are
given over each chapter to assess the student's understanding of the material. Each chapter test consists of
questions taken from the review questions and problems at the end of each chapter. Students must take the exam in the
presence of the instructor or designated proctor and may not use their books or notes on the tests. Students are
encouraged to keep a journal in which they answer the review questions and problems at the end of each chapter. This
is the best way to prepare for the chapter tests. The average of the chapter tests will count 30% of the total
grade. Student's may retake one test during RETEST week which is one week before final exam week.
Short Quizzes
Short 10 minute quizzes are frequently given to assess the
student's comprehension of topics recently covered in the course. Students may not use their notes or books on the in-class
short quizzes. Students also take practice
tests over each chapter as preparation for real tests over each chapter. Scores on these pretests are treated like short quizzes.
The lowest short quiz will be
dropped at the end of the course before calculating the short quiz average.
Student-Centered
Activities
Students learn best by doing rather than listening. A number of student-centered activities
have been developed to promote active learning. These activities include:
The design and simulation of a
planetary system using software such as "Interactive Physics"
Making measurements of light intensity,
temperature, and other physical quantities discussed in the course using sensors and probes from PASCO Scientific's
Science Workshop microcomputer interface.
Use of Voyager Sky Gazer and Starry Night astronomy software to
learn the names of stars and their location within major constellations; observe the position of the moon, sun, and
planets as they move across the celestial sphere during the course.
The average of the hands-on
activities will count 25% of the total grade. A student will receive a zero on any uncompleted activity.
Comprehensive Final Exam
A comprehensive final examination will be given
which includes questions from chapter tests, quizzes, and hands-on-activities, The final exam will count 25% of
the total grade.
Calculating the final numerical grade
average:
Example: Suppose the average of the chapter tests is 80. Since the chapter tests count as
30% of the grade, take 80 and multiply by 0.30. Now let's say the student has a 70 short quiz/homework average
(after the lowest quiz is dropped). Since the short quizzes count for 20% of grade, take 70 and multiply by 0.20.
Let's assume the student received a 84 on the hands-on activities. Since this counts for 25% of the grade, we
multiply 90 by 0.25. Finally, let's suppose the student makes a 72 on the comprehensive exam. Since this exam counts
for 25% of the grade, we multiply the 72 x 0.25.
The total points which have earned is therefore:
80(0.30) + 70(0.20) + 84(0.25) + 72(0.25) = 24 + 14 + 21 + 18 = 77 = C+.

numerical average and corresponding letter grade appears in the table below.

Specific Directions or Recommendations
- NO FOOD OR BEVERAGES ARE PERMITTED IN LECTURE ROOMS AND LABORATORIES !
In your student handbook you will find the statement "Food and beverages are allowed in the cafeteria and student
lounge only." Please respect this rule. The physics and computer lecture / laboratory rooms contain computers and
electronics equipment which can be seriously damaged if exposed to liquids and food particles. There is also the
potential risk of fire and/or electrocution if such equipment is accidentally short-circuited by spilled beverages
and foods.
- A scientific calculator is required. Most scientific calculators can be
purchased for less than $20.
If you have a documented disability which may affect your performance in this
course, please advise the instructor immediately so appropriate accommodations may be put in place. Accommodations
may be arranged through the Disabilities Service Coordinator in room #104. Accommodations and assistive technology
are available to students at no additional cost, and should be accessed at the beginning of each semester.
Class Attendance Policy
This course uses the General Attendance
Policy as outlined in the student handbook. This states that the number of class or lab absences in a
semester/session may not exceed the number of times the course meets in one week. Since this course meets two times
each week for 75 minutes, the number of unexcused absences is two. Absence from any portion of a class may be counted
as an absence. Excessive absences may result in the following sanctions:
- After two unexcused
absences, the student will receive a written warning stating that he/she will be withdrawn from the course after the
next unexcused absence. A copy of this warning will go to the student's advisor and the Dean of Academic Affairs.
- When the number of absences exceeds the number permitted by the instructor, the student may be suspended from
that course at the discretion of the instructor. The instructor will send a written notice to the student, the
Registrar and the student's advisor, indicating that the student has been withdrawn from the course. The instructor
has the option of assigning a grade of AW (Administrative Withdrawal) or AF (Administrative Failure) which will
appear on the student's transcript. An AW grade is not computed into the grade point average. An AF grade is
recorded as a failing grade and will be computed into the student's grade point average.
- Your instructor in
this course is under no obligation to provide makeup of lectures, hands-on activities, quizzes, tests or other
information missed due to an unexcused absence.
- College-sponsored events such as field trips and athletic
games are considered excused absences; course work, tests, and quizzes may be made up if the absence is because of a
college-sponsored activity.
- Students receiving financial aid or veterans benefits may be expected to attend
class regularly as a condition of receiving such aid. Verification may be requested by the aid source.
