Ch 27: OAE - Integrated Science: Evolution of the Solar System & Universe

About This Chapter

The OAE Integrated Science exam features a series of questions about the birth and growth of the universe and our solar system. Our study guide will help you review this topic so that you can gain your Ohio teaching license.

OAE Integrated Science: Evolution of the Solar System & Universe - Chapter Summary

This chapter will review the different parts of the known universe. It will provide textbook definitions of solar systems and galaxies, and it will then provide a brief overview of the development of the universe. The chapter will explore giant and dwarf stars as well as the formation of the Milky Way galaxy. The lessons will help you review and master:

  • The differences between solar systems, universes and galaxies
  • The beginnings of the universe
  • Evidence for the Big Bang Theory
  • How galaxies form
  • The formation of our solar system
  • Types of stars and their formation
  • The life cycle of a star

The lessons start with the largest unit of space, the universe, and slowly zoom into the smaller parts. This will help you intuitively organize your existing knowledge. The lessons also have short comprehension checks that echo the format of the OAE exam.

OAE Integrated Science: Evolution of the Solar System & Universe Chapter Objectives

The OAE Integrated Science exam has 150 multiple-choice questions to be completed in 180 minutes. The test is computer-based. The exam covers four domains of scientific knowledge: the nature of science, Earth and space science, life science, and physical science. This chapter is part of the Earth and space science domain, which is the equivalent of 19% of the exam.

Solar System, Galaxy, & Universe: Definitions & Difference

1. 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.

Origins of the Universe: The Big Bang and Expanding & Contracting Universes

2. Origins of the Universe: The Big Bang and Expanding & Contracting Universes

Students will learn the origins of the universe, the Big Bang theory, the timeline of the universe, how the universe is still expanding to this day, and what astronomers expect the universe to look like in the future.

Evidence for the Big Bang Theory: Background Radiation, Red-Shift and Expansion

3. Evidence for the Big Bang Theory: Background Radiation, Red-Shift and Expansion

Discover what evidence exists to support the Big Bang theory of the birth of the universe. Learn how cosmic background radiation, the red shift of light and the ongoing expansion of the universe led scientists to believe that the universe was started with the Big Bang.

Galaxy Formation: Spiral, Elliptical & Irregular Galaxies

4. Galaxy Formation: Spiral, Elliptical & Irregular Galaxies

This lesson explains how galaxies form, starting with the Big Bang. You'll also learn about the solar nebula hypothesis and three galaxy types, including spiral, elliptical, and irregular galaxies.

The Formation of the Milky Way Galaxy

5. The Formation of the Milky Way Galaxy

This lesson will explore two hypotheses as to how the Milky Way galaxy formed. These are the top-down and bottom-up hypotheses. We'll also go into what special connection you personally have to all of this.

The Solar Nebula Theory: Formation of the Solar System

6. The Solar Nebula Theory: Formation of the Solar System

This lesson will go over the theory that explains how the solar system formed, what theory had once competed with it, and what important implication this theory carries.

Star Formation: Main Sequence, Dwarf & Giant Stars

7. Star Formation: Main Sequence, Dwarf & Giant Stars

Learn how stars are born, beginning with a protostar. Then learn about stars in later stages of life, including main sequence stars, brown dwarfs, red giants, and black holes.

Types of Stars by Size, Color and Life Cycle

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

Learn to identify the different sizes and colors of stars and how they relate to the star life cycle. In this lesson, we'll talk about spectral classification, how many stars there are of each type and the approximate color of the different classes of stars.

Supernova and Supergiant Star Life Cycle

9. Supernova and Supergiant Star Life Cycle

Learn about one of the biggest explosions known to humankind - a supernova. Follow a star's life cycle and learn how a star changes from a red giant to a supernova to a black hole or neutron star.

Life Cycle of Neutron Stars

10. Life Cycle of Neutron Stars

Discover the life of a neutron star, including how it's born after a supernova explosion and how its extreme pressure causes protons and electrons to combine into neutrons. Discover also how pulsars are rotating neutron stars that will eventually slow down to become regular neutron stars.
