Ch 3: ORELA General Science: Scientific Laws & Theories

About This Chapter

Our video lessons and quizzes in this chapter will give you a comprehensive overview of significant scientific theories and laws so you can be ready for related questions on the ORELA General Science exam.

ORELA General Science: Scientific Laws & Theories - Chapter Summary

If you're going to take the ORELA General Science exam soon, you'll want to know as much as possible about scientific laws and theories. If you need a little extra help preparing for questions about relevant theories, voyages and definitions, don't worry; we've got you covered! Our expert instructors, who created the videos, are available if you need additional help. They'll guide you through the essentials of scientific laws and theories, including, but not limited to:

  • Theory of relativity
  • Laws of universal gravitation and thermodynamics
  • The Scientific Revolution
  • Buoyancy
  • Hubble's law
  • The theories of Charles Darwin
  • Sir Isaac Newton's contributions to astronomy
  • Atomic theories of Dalton, Thomson, Rutherford and Millikan

In our chapter, you'll find brief video lessons that will thoroughly and succinctly review scientific laws and theories. Since each video is really easy to navigate, you can re-watch parts or the entire thing as many times as you need. Short practice quizzes follow each video so you can find any weak links in your comprehension or retention.

Objectives for the ORELA General Science: Scientific Laws & Theories Chapter

The ORELA General Science exam is what the state of Oregon uses to determine eligibility for science teacher certification or endorsement. This is a computer-based test of 150 multiple-choice questions subdivided into four domains. Questions about scientific laws and theories could show up on any of the domains.

The first domain, Nature of Science, may include questions assessing your ability to analyze evidence of scientific claims, demonstrate understanding of the development of major scientific ideas through history, and demonstrate knowledge of current major theories in the physical, life, earth and space sciences. The second domain, Physical Science, could assess your ability to analyze historical and modern atomic theories and apply laws of thermodynamics and gravitation.

The third domain, Life Science, is likely to include questions testing your knowledge of theories of the origin of life and diversity. The fourth domain, Earth and Space Science, may assess your familiarity with theories regarding the origin of the universe, as well as your understanding of the role of gravity in the universe.

10 Lessons in Chapter 3: ORELA General Science: Scientific Laws & Theories
The Role of Scientific Knowledge in Research & Peer Review

1. The Role of Scientific Knowledge in Research & Peer Review

Learn about how research and peer review leads to scientific knowledge through the scientific process, and discover some of the key elements and themes in science.

Theory of Relativity: Definition & Example

2. 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.

The Law of Universal Gravitation: Definition, Importance & Examples

3. The Law of Universal Gravitation: Definition, Importance & Examples

Gravity is what pulls us toward Earth, but it's also what pulls Earth toward us. This is explained by the law of universal gravitation, which describes how all objects in the universe have this important force between them.

Buoyancy: Calculating Force and Density with Archimedes' Principle

4. Buoyancy: Calculating Force and Density with Archimedes' Principle

Knowledge of the buoyant force is important when trying to understand why some objects float while other objects sink. In this lesson you'll learn about this unique force and how we apply it to various situations using Archimedes' Principle.

The Laws of Thermodynamics

5. The Laws of Thermodynamics

Learn about the first and second laws of thermodynamics. Find out how energy is generated, how it converts from one form to another, and what happens to energy in a closed system.

Kepler's Role in the Scientific Revolution

6. Kepler's Role in the Scientific Revolution

In this lesson, we will learn about the role Johannes Kepler played in the Scientific Revolution. We will identify his major contributions and learn why he was important.

Hubble's Law & Hubble's Constant

7. Hubble's Law & Hubble's Constant

This lesson will go over and define the Hubble Law and Hubble constant. We'll not only do a practice problem but also define conceptually what these two things mean to our cosmos.

Charles Darwin: Voyages, Theories & Works

8. Charles Darwin: Voyages, Theories & Works

In this lesson we explore the life and voyages of the 19th-century British naturalist Charles Darwin and his formulation of the theory of natural selection.

Sir Isaac Newton And Astronomy

9. 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.

Early Atomic Theory: Dalton, Thomson, Rutherford and Millikan

10. 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.
