1. Formation of the Earth: Theories
In this lesson, the theory of how the planet Earth formed will be discussed. This includes looking at how it differentiated into three layers, how it formed its atmosphere, water, and land features, and how it continues to evolve today.
2. Formation of the Moon: Theories
Explore the four major theories on the formation of the Moon. The theories include the fission theory, capture theory, condensation theory and giant impact theory. Also look at both information supporting and flaws found in these theories.
3. 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.
4. The History of Life on Earth: Timeline and Characteristics of Major Eras
The Earth is over 4.6 billion years old. Ever wonder what happened during certain time periods in that large amount of time? We will look at the major eons and eras of Earth's history along with important characteristics of each.
