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. 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.
5. 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.
6. 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.
7. 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.
8. The History of Life on Earth: Timeline and Characteristics of Major Eras
The Earth is over 4 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.
9. Ice Age: Definition, History & Timeline
What is an ice age and what factors interact to cause them? This lesson helps answer those questions with the help of graphics and discussion. A lesson summary and brief quiz are also included.
10. The Cambrian Explosion: Definition & Timeline
The Cambrian Explosion refers to the metaphorical explosion of life that began 542 million years ago and lasted for roughly 40 million years. This lesson will cover the events that occurred during this time period.
11. The Precambrian Period: Events & Facts
The earth as we know it today is shaped by what happened during the Precambrian period, which covers four billion years! This lesson covers the events that shaped this important period.
12. Theropod Dinosaurs: Definition & Types
In this lesson, we will look at some examples of theropods, which were the bipedal, carnivorous dinosaurs such as the Tyrannosaurus rex from which birds have descended.
