AST 101IN - Solar System

4 Credits, 6 Contact Hours
3 lecture periods 3 lab periods

Introduction to the science of the nature and origin of the solar system: the sun and its family of planets, along with comets and asteroids. Includes the history of astronomy and special topics regarding the space program. Also includes scientific thinking as an application of critical and quantitative thinking, and science in contrast to pseudoscience. Also includes in-class measuremental and mathematical exercises, outside observation projects, independent studies, and self-initiated trips to local astronomy facilities.

Gen-Ed: Meets AGEC - SCI; Meets CTE - M&S.

Course Learning Outcomes
  1. Discuss how astronomical observations contributed to the scientific revolution of the 17th century and explain the evidence for a heliocentric model for our solar system.
  2. Describe and explain the apparent motions of celestial bodies as seen from an observer on Earth, and apply this knowledge in order to predict positions and appearances of objects on the sky as a function of time and the observer’s location.
  3. Describe current theories of planet formation and relate these to the present-day structure of our own solar system.
  4. Recognize the immense spatial and time scales of the solar system, and compare and contrast these with human scales using scientific notation, distance ranking and scale models.
  5. Predict orbital parameters for gravitating systems by applying Kepler’s laws of planetary motion and Newton’s laws of motion and Universal Gravitation.

Performance Objectives:
  1. Demonstrate improvement in critical and quantitative thinking by applying the scientific method to fact and theory in classroom learning, activities (some quantitative and mathematical), and assignments (some quantitative and mathematical).
  2. Distinguish science from pseudoscience.
  3. Describe the overall structure and individual components of the solar system.
  4. Describe the solar system’s origin.
  5. Explain the historical development and multi-cultural aspects of the practice of science generally, and astronomy, specifically.
  6. Outline the technical development of modern astronomy and space exploration.
  7. Generate or expand global awareness by integrating astronomy’s cosmic, worldwide and multi-cultural perspective of earth with insights gained from its historical development, and scientific and societal impacts.
  8. Demonstrate the improvement in critical and quantitative thinking by analyzing astronomical observations related to specific information covered in lectures.
  9. Expand global awareness by identifying aspects of the sky and recording common sky phenomena, utilizing the naked eye or binoculars.
  10. Expand global awareness by examining and describing the sky more closely based on at least one telescope viewing experience. 
  11. Describe astronomical and astronomy-related facilities in the Tucson area.
  12. Discuss the Tucson area’s importance to the field of astronomy and astronomy’s role in the local economy.
