COURSE DESCRIPTION:
This introductory course in Astronomy covers the study of planets, stars, galaxies and the Cosmos. Knowledge of the Universe and of the laws governing its behaviour bring students on a journey of exploration and discovery from local neighbouring planets in our solar system, beyond nearby stars and galaxies, out to the confines of the known observable Universe.
SUMMARY OF COURSE CONTENT:
Topics of study are divided into four sections:
The night sky: constellations, stars and their motion.
The solar system: planetary motion; Aristotle to Galileo; Kepler’s laws; Newton’s theory of gravity; structure of the solar system; properties of planets.
Stellar physics: the atom; nuclear fusion; development of stars; electromagnetic spectrum; atomic spectra; black-body radiation; properties and types of stars; the HR diagram; measuring distances to stars.
Cosmology: Olber’s paradox; Doppler shift; Hubble and the expanding universe; the Big Bang theory; dark matter; future of the universe.
LEARNING OUTCOMES:
Upon completion of the course students should be able to:
- identify some planets, stars and constellations in the night sky;
- describe astronomical events such as star formation and supernovae;
- apply laws of physics to predict behaviour of various bodies in the universe;
- use mathematical operations to calculate astronomical quantities;
- read and interpret information from graphs;
- outline the historical development of Astronomy.

GRADING POLICY
-ASSESSMENT METHODS:
AssignmentGuidelinesWeight
Attendance and class participation 15 %
HomeworkHomework assignments will be graded: the average grade weighs 15 percent of the final grade.15 %
Mid-term exam 30 %
Final exam (comprehensive) 40 %

-ASSESSMENT CRITERIA:
AWork of this quality directly addresses the question or problem raised and provides a coherent argument displaying an extensive knowledge of relevant information or content. This type of work demonstrates the ability to critically evaluate concepts and theory and has an element of novelty and originality. There is clear evidence of a significant amount of reading beyond that required for the course.
BThis is highly competent level of performance and directly addresses the question or problem raised.There is a demonstration of some ability to critically evaluatetheory and concepts and relate them to practice. Discussions reflect the student’s own arguments and are not simply a repetition of standard lecture andreference material. The work does not suffer from any major errors or omissions and provides evidence of reading beyond the required assignments.
CThis is an acceptable level of performance and provides answers that are clear but limited, reflecting the information offered in the lectures and reference readings.
DThis level of performances demonstrates that the student lacks a coherent grasp of the material.Important information is omitted and irrelevant points included.In effect, the student has barely done enough to persuade the instructor that s/he should not fail.
FThis work fails to show any knowledge or understanding of the issues raised in the question. Most of the material in the answer is irrelevant.

-ATTENDANCE REQUIREMENTS:
Full credit for attendance will be given to students with three or fewer unexcused absences. Four or more absences will result in a proportional reduction of the grade.
ACADEMIC HONESTY
As stated in the university catalog, any student who commits an act of academic dishonesty will receive a failing grade on the work in which the dishonesty occurred. In addition, acts of academic dishonesty, irrespective of the weight of the assignment, may result in the student receiving a failing grade in the course. Instances of academic dishonesty will be reported to the Dean of Academic Affairs. A student who is reported twice for academic dishonesty is subject to summary dismissal from the University. In such a case, the Academic Council will then make a recommendation to the President, who will make the final decision.
STUDENTS WITH LEARNING OR OTHER DISABILITIES
John Cabot University does not discriminate on the basis of disability or handicap. Students with approved accommodations must inform their professors at the beginning of the term. Please see the website for the complete policy.
