Astronomy Part 2
LI.SCI.301612.2.CE
Course Length: 1 Semester
Has Textbook: Yes
Part 2 of Astronomy takes a step outside planet Earth and takes an in-depth look at the discovery and exploration of the Milky Way galaxy. Students will analyze the Big Bang theory and evidence that supports the creation of our solar system. Students will then explore the creation and properties of terrestrial and gaseous planets, and they will recognize what makes each planet unique. Lastly, students will explore foreign bodies of the solar system, such as meteors, asteroids, comets, and asteroid and comet impacts. This course will utilize interactive labs and a textbook.
It is recommended that students successfully complete Astronomy Part 1 or equivalent course work before enrolling in this course.


Course Objectives

Unit 1: Essential Content and Skills

  • Examine the different observations that lead up to the discovery of the Milky Way Galaxy.
  • Determine the structure of the galaxy by analyzing the components and mass of the galaxy.
  • Determine how the galaxy formed by analyzing the properties of star populations.
  • Determine how to classify the galaxies in our universe by examining the three main types of galaxies and how they are organized.
  • Determine how to measure the properties of galaxies by examining Hubble Law and Hubble Constant.
  • Determine how to measure the properties of galaxies by discussing the different ranges of galaxy masses.
  • Discuss supermassive black holes by examining their characteristics and how they form.

Unit 2: Essential Content and Skills

  • Discuss a theory of how the universe was created by analyzing moments of the Big Bang.
  • Determine how the universe is expanding in dimensions of both space and time.
  • Discuss how scientists are exploring and observing our universe at the large-scale to help confirm known theories of the universe and the Big Bang.
