Ch 26: CSET: Astronomy

About This Chapter

Let our instructors help you understand the structure and composition of the universe. The video lessons and self-assessment quizzes provide several approaches to help you correctly answer astronomy questions on the CSET Science test.

CSET: Astronomy - Chapter Summary

This chapter's video lessons can assist you in gaining a solid understanding of astronomy as you prepare for the General Science portion of the California Subject Examinations for Teachers (CSET). You'll learn basic facts about the composition of the universe, how stars produce light and the predictable cycles of the stars, planets and other bodies. Other videos explore the planets in our solar system and explain how telescopes work. Here are some of the topics covered that will help you get ready for the examination:

  • Chemical composition and physical structure of the universe
  • Galaxy formation: Spiral, elliptical and irregular galaxies
  • Inner, outer and dwarf planets of our solar system
  • Types of stars by size, color and life cycles
  • Structure of the sun
  • Stages of the sun's life cycle
  • Difference between stars and parents
  • Supernova and supergiant star life cycle
  • Star formation
  • Phases of the moon
  • How fusion in stars produces heavier elements
  • Radio, reflecting and refracting telescopes
  • Use of astronomical units and light years to describe distances

An expert instructor will lead you through each lesson, going over the astronomy facts you'll need on the CSET Science test. The videos make learning about astronomy entertaining, and the lessons and self-assessment quizzes will give you sound background knowledge in how the universe operates.

Objectives of the CSET: Astronomy Chapter

The CSET program consists of tests for those California teachers who are required by the state to pass subject examinations for credentialing. The astronomy portion of the CSET is included in the General Science: Subtest I. There are 58 multiple-choice questions on the science subtest, and seven of those are on astronomy. You can use the self-assessment quizzes that are included with each video lesson to become familiar with the test format, as well as to test your knowledge of astronomy.

Types of Stars by Size, Color and Life Cycle

1. Types of Stars by Size, Color and Life Cycle

Not all stars are the same. Learn about the different types of stars, and explore their sizes, colors, temperatures, and life cycles. Review spectral classifications and identify classes of stars.

Astronomical Units & Light Years: Definition & Examples

2. Astronomical Units & Light Years: Definition & Examples

After watching this video, you will be able to explain why we need special astronomical ways of measuring distance. You will also be able to state the meaning of the terms astronomical unit, light year and parsec. A short quiz will follow.

Relating a Star's Brightness to Luminosity

3. Relating a Star's Brightness to Luminosity

The luminosity of a star and its brightness is related to each other and are related by an equation. Learn about wattage, luminosity, the inverse square law, and how to use luminosity to determine the apparent brightness.

Nuclear Fusion & Star Formation

4. Nuclear Fusion & Star Formation

The formation of stars results in a nuclear fusion that will continue to generate energy until the star burns out. Learn about nuclear fusion, the balance of forces during fusion, and understand how nuclear fusion cannot begin in a star until a specific internal temperature is reached.

Formation, Types & Life Cycles of Stars

5. Formation, Types & Life Cycles of Stars

After reading this lesson, you will be able to describe how stars form and what form they take as well as describing the common cycles of their lives. A short quiz will follow.

Solar System, Galaxy, & Universe: Definitions & Difference

6. Solar System, Galaxy, & Universe: Definitions & Difference

Want to learn what the universe, galaxy, and solar system are as well as some cool facts about each one? This lesson will give you an overview of what these three things are in a relatable fashion.

What is a Solar System? - Planets & Model

7. What is a Solar System? - Planets & Model

The solar system consists of the sun, planets, moons, and all the other objects within the gravitational pull of the sun. Learn about the definition of the solar system, its formation and model, as well as the different objects within the solar system.

Major Characteristics of Planets in the Solar System

8. Major Characteristics of Planets in the Solar System

This lesson will go over some characteristics of the planets in our solar system with respect to their masses, diameters, temperatures, densities, and rotation.

Interactions in the Sun-Earth-Moon System

9. Interactions in the Sun-Earth-Moon System

Learn how the sun, earth, and moon interact with each other to create tides, phases, eclipses, seasons, solar winds, and precession. Take a quiz and see how much you've picked up.

Kepler's Three Laws of Planetary Motion

10. Kepler's Three Laws of Planetary Motion

Johannes Kepler, a German astronomer and a mathematician active in the 16th century, formed three laws of planetary motion. Learn about Kepler's life, his studying with the world's most respected astronomer at the time, Tycho Brahe, as well as Kepler's three laws of planetary motion.

Types of Telescopes: Radio, Reflecting & Refracting Telescopes

11. Types of Telescopes: Radio, Reflecting & Refracting Telescopes

Telescopes provide a means to explore the universe. Learn about different types of telescopes, including radio, x-ray, gamma ray, reflecting, and refracting telescopes.
