Ch 2: General Science: Scientific Laws & Theories

About This Chapter

In the state of Arizona the NES General Science exam has replaced the AEPA General Science test. With this chapter review some of the historically influential laws and theories of physics, chemistry, biology and astronomy as you study for the NES General Science exam.

AEPA General Science: Scientific Laws & Theories - Chapter Summary

Complete the activities of this chapter to reinforce your knowledge about the laws and theories of physics, chemistry, biology and astronomy that have proven to be influential in the studies of these sciences. Start by watching our instructors in this series of lesson videos that will aid in your review for questions on the National Evaluation Series (NES) General Science exam about:

  • Theory of relativity
  • Newton's law of universal gravitation
  • Buoyancy and Archimedes' principle
  • Laws of thermodynamics
  • Kepler and the scientific revolution
  • Hubble's law
  • Theories and works of Charles Darwin
  • Early atomic theory

Accompanying these lesson videos are lesson quizzes designed to test your retention of the information presented in the lessons. Take these quizzes to find topics that you don't understand, and then return to the areas of the lessons that discuss these subjects via the video tags. Once you've completed the lessons and quizzes, be sure to assess how well you understand the material of this chapter by taking the practice chapter exam.

9 Lessons in Chapter 2: General Science: Scientific Laws & Theories
Test your knowledge with a 30-question chapter practice test
Theory of Relativity: Definition & Example

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.

The Law of Universal Gravitation: Definition, Importance & Examples

2. 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

3. 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

4. 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

5. 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

6. 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

7. 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

8. 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

9. 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.
