1. The Scientific Field of Astronomy
Space is a large and exciting place, full of things we have yet to discover. Astronomy aims to uncover the mysteries of space, something people have been fascinated with as long as they have been on Earth.
2. The Ancient Study of Astronomy
This lesson will teach you about three important cultures and civilizations that contributed much to our understanding of astronomy. They include the Babylonians, Maya, and Greeks.
3. The Constellations: Definition & Name Origins
This lesson will teach you about ancient constellations and how they came to be. We'll define modern constellations and learn why they're important. You'll also learn about the differences between a constellation and an asterism.
4. The Lunar Calendar & Metonic Cycle
This lesson will discuss the lunar calendar, luni-solar calendar, the Metonic cycle, and how they relate to keeping time in the ancient world and even some calendars today.
5. The Connection Between the Seven Days of the Week & Astronomical Objects
This lesson will explain to you why the English language has its current names for its days of the week and what Roman gods and Anglo-Saxons have to do with it.
6. Geocentric, Heliocentric & Ptolemaic Models of the Universe
This lesson will lay out for you how ancient Greek philosophers came up with their models of the universe,. We'll also look at who Ptolemy was and what he contributed, and whether or not the Greeks were correct.
7. The Copernican Revolution
This lesson will discuss a famous astronomer by the name of Nicolaus Copernicus, his early history, his revolutionary idea, and why his model of the universe was actually wrong.
8. Tycho Brahe's Contribution to Astronomy
There was a man who did not believe Ptolemy's version of the universe nor did he believe in Copernicus's views on the universe. Who was this daring man? He was Tycho Brahe. We'll learn about him in this lesson.
9. Kepler's Three Laws of Planetary Motion
Find out about the interesting life and major contributions of Johannes Kepler. This lesson will also teach you how to find out how long it takes a planet to revolve around the sun!
10. Galileo, the Telescope & the Church
This lesson explores the contributions of Galileo to modern science. It examines his early steps toward a scientific method, his work on falling bodies and, of course, his astronomical discoveries. Finally, the Church's reaction to these discoveries is explored.
11. Sir Isaac Newton And Astronomy
This lesson will teach you about Newton's laws of motion and universal gravitation as well as why the moon doesn't fly off into space and why it doesn't crash into the Earth.
12. Origins of the Julian & Gregorian Calendars
The Julian calendar and Gregorian calendar were both revolutionary in their own right. Find out who's responsible for putting them into place and which one of the two we use today and why.
