This lesson will explore the basic nature of science. It will distinguish science from pseudoscience and hypothesis from theory and natural law; it will give plenty of examples of each.

What is Scientific Research?

2. What is Scientific Research?

This lesson will discuss important components of scientific research, including the scientific method, peer review, statistical significance, and more!

The Scientific Method: Steps, Terms & Examples

3. The Scientific Method: Steps, Terms & Examples

The scientific method is more than just hypotheses and experiments. In this lesson, we'll explore the themes and variations that make up the world of science.

Developing a Scientific Hypothesis

4. Developing a Scientific Hypothesis

This video describes how to create a hypothesis and includes the three main things needed to create a strong hypothesis. You'll learn how to make a clear statement that can be both tested and measured.

What is the Scientific Theory? - Definition, Characteristics & Example

5. What is the Scientific Theory? - Definition, Characteristics & Example

In this lesson, you'll learn the definition and characteristics of a scientific theory and understand how theories are formulated. You'll see examples of scientific theories, and after the lesson you can test your knowledge with a brief quiz.

True Experimental Design

6. True Experimental Design

Experiments are the classic way to conduct research in almost any field of study. But do you know how true experiments really work? This lesson explains the details of experimental design, such as different types of samples, control groups and independent vs. dependent variables.

Sampling Techniques In Scientific Investigations

7. Sampling Techniques In Scientific Investigations

We can learn a lot by gathering information from a small subset of a larger group. By sampling this smaller group, scientists can save time and money while still gaining a good understanding of the population as a whole.

What Are The Different Kinds of Research Methods?

8. What Are The Different Kinds of Research Methods?

This lesson will go over some important research methods, including observation, correlation, and experimentation, as well as examples of each type of methodology.

Research Variables: Dependent, Independent, Control, Extraneous & Moderator

9. Research Variables: Dependent, Independent, Control, Extraneous & Moderator

This lesson explores the terminology of experimental design. What are variables? How do they influence each other? Is it possible that you are seeing connections that don't actually exist?

Inductive vs. Deductive Reasoning: Differences & Examples

10. Inductive vs. Deductive Reasoning: Differences & Examples

This lesson explores the difference between inductive and deductive reasoning in the form of psychological experiments. In addition to defining these terms, the lesson gives examples to explain how this reasoning is applied.

The Advance of Science & Technology Since 1945: Developments & Impact

11. The Advance of Science & Technology Since 1945: Developments & Impact

In this lesson, we explore just a few of the numerous advances and innovations made in the worlds of sciences and technology, from automobiles and televisions to computers and phones that can fit in the palm of your hand.
