About This Chapter
OAE Earth and Space Science: Modern Scientific Theories - Chapter Summary
This chapter discusses theories and principles that pertain to evolution, relativity and quantum physics. Prior to sitting for the OAE Earth and Space Science examination, use the lessons to review topics such as biogeography, the Rutherford model and endosymbiosis. Refresh your memory of atomic spectra and enhance your knowledge of the mass-energy equivalence equation. This chapter might also assist you with:
- Explaining the theory of relativity
- Discussing quantum theory
- Understanding the evolution of the universe and presenting supporting evidence
- Describing the history of atomic theory
- Discussing the development of the Bohr model
- Examining the basis for the Watson and Crick model of DNA
- Interpreting the theory of endosymbiosis
After going through the lessons and brushing up on these topics, you could more accurately answer OAE Earth and Space Science questions on modern scientific theories. The lessons are short, yet filled with information that can improve your examination performance. Video lessons include navigational video tags and text transcripts and all lessons come with an accompanying multiple-choice practice quizzes. You can submit any questions to our science experts.
OAE Earth and Space Science - Modern Scientific Theories - Chapter Objectives
Questions on modern scientific theories and ideas are included in the Nature of Science domain of the OAE Earth and Space Science examination. This first domain of the five-part test is equal to 18% of the entire assessment score. There are 150 multiple-choice questions on the computer-administered examination. You'll be allowed 180 minutes for completion, which doesn't include a 15-minute computer-based tutorial.
1. Theory of Relativity: Definition & Example
Watch this video lesson, and you will learn about the theory of special relativity and how it applies to you. Learn how you can use one of the most famous equations from this theory to calculate the power inside just one tiny object.
2. Quantum Theory: Definition & Examples
After watching this lesson you will be able to explain what quantum theory is, including some key principles and scenarios, and list some applications of quantum theory. A short quiz will follow..
3. The Evolution of the Early Universe
This lesson will describe four important stages of development in the early universe, the radiation era, recombination (decoupling) epoch, the dark age, and reionization era.
4. Scientific Evidence That Supports Evolution
Evolution explains how species that are present on Earth today are modified descendants of their ancestors. This scientific theory is supported by many different types of evidence, which show how evolution is a very real and natural phenomenon.
5. Early Atomic Theory: Dalton, Thomson, Rutherford and Millikan
Imagine firing a bullet at a piece of tissue paper and having it bounce back at you! You would probably be just as surprised as Rutherford when he discovered the nucleus. In this lesson, we are going to travel back in time and discuss some of the major discoveries in the history of the atom.
6. The Bohr Model and Atomic Spectra
Do you ever wonder where light comes from or how it is produced? In this lesson, we are going to use our knowledge of the electron configurations and quantum numbers to see what goes on during the creation of light.
7. Watson & Crick Model of DNA
This lesson will review the Watson & Crick model of DNA and how it applies to our understanding of genetic material. By the end you will understand what Watson and Crick discovered and explain what its structure looks like.
8. The Endosymbiosis Theory: Evolution of Cells
Ever wonder why some cells are very simple and others are complex with countless organelles to remember? We will look at how simple cells evolved to become more complex cells - as well as evidence to support this.
