About This Chapter
Intro to the Solar System & the Universe - Chapter Summary
In this chapter, we've provided a series of short and engaging videos on the solar system and the universe. You'll study the origins of the universe, evidence of the Big Bang theory, galaxy formation and the solar nebula theory. Additional topics include the outer and inner planets of the solar system and the dwarf planets. Once you complete this chapter, you should be ready to:
- Describe meteorites, comets and asteroids
- Explain the main sequence of star formation
- Outline the types of stars by color, size and life cycle
- Discuss the structure of the sun
- Identify the stages of the sun's life cycle
- Explain interactions in the Sun-Earth-Moon system
- Detail how gravity in the solar system shapes stars and planets
- Use technology to study the universe and Earth
All of our videos are accompanied by multiple-choice quizzes so you can be sure you're ready for exam day or to move on to other subjects. Going back to review any of the video sections over again is easy with the timeline feature. If any of the subjects are confusing, submit any questions you have through the dashboard for one of our experts to answer.
1. 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.
2. 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.
3. 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.
4. 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.
5. Outer Planets of the Solar System: Jupiter, Saturn, Uranus, Neptune
Take a tour of the outer planets of our solar system: Jupiter, Saturn, Uranus, and Neptune. Find out what makes each of these gas giants unique and learn about Pluto, a dwarf planet.
6. Inner Planets of the Solar System: Mercury, Venus, Earth & Mars
Take a tour of the four inner planets: Mercury, Venus, Earth and Mars. Known as the terrestrial planets, find out what makes each of them unique and how they are different from the outer planets, the gas giants.
7. Dwarf Planets of the Solar System: Pluto, Eris, Haumea & Ceres
Discover why Pluto had to leave the league of planets and was downgraded to a dwarf planet. Learn the definitions for planet and dwarf planet. Find out about the currently classified dwarf planets in our solar system: Pluto, Eris, Ceres, Haumea and Makemake.
8. Asteroids, Meteorites & Comets: Definitions and Characteristics
This lesson will cover the definitions and characteristics of asteroids, comets and meteorites. It will also explore what impact they have had on Earth and the impact they might have in the future.
9. 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.
10. 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.
11. Structure of the Sun
Discover the layers of the sun, including the core, radiative zone, convective zone, photosphere, chromosphere, and corona. Find out which layers you can see from Earth. Investigate what sunspots and solar flares are.
12. Stages of the Sun's Life Cycle
Discover our sun, the provider of energy for life on Earth. Learn how the sun was born, how it lives as a main sequence star, how it will age into a red giant and how it will die as a white dwarf.
13. 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.
14. Gravity in the Solar System: Shaping Planets & Stars
After watching this video, you will be able to explain what gravity is, and the role it plays in forming the shapes of planets and stars. A short quiz will follow.
15. Using Technology to Study the Earth & Universe
Have you ever wondered how we know so much about the universe? Learn about how we use technology to study the universe, from the tiny to the enormous. Then take a quiz to test your knowledge.
