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. 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.
3. 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.
4. 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.
5. What is Orbit? - Planets & Satellites
This lesson talks about what an orbit is and defines some common terms associates with orbit. We also talk specifically about orbits of planets and satellites.
6. Important Points on the Celestial Sphere

7. 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.
8. Stars: Definition & Facts
Before you name a star after someone, get the facts! Stars are a lot more than pretty lights up in the sky. Complete this lesson to learn more about nuclear fusion, main sequence stars, red giants, and more.
9. Galaxy: Definition & Explanation
Galaxies are collections of stars, dust, and gas rotating around super massive black holes. This lesson will cover the structures and types of galaxies, including spiral, elliptical, and irregular galaxies.
10. 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.
11. 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.
