Ch 2: Scientific Experiments & Research

About This Chapter

Review the video lessons contained in this chapter to learn the basics of scientific experiments and research. The instructors of each lesson will provide you with comprehensive overviews of key topics relevant to this subject.

Scientific Experiments & Research - Chapter Summary

If you want to understand science as a whole, you should start by understanding the processes and methods involved in scientific research and experimentation. To this end, you can watch the video lessons contained within this chapter for helpful, interactive instruction on all of the main topics needed to properly understand this subject.

These lessons will go over the principles involved in the construction of scientific experiments and research, as well the different tools and methods that are utilized when scientists try to better understand the world. The lessons will also provide you with examples of each topic discussed here to ensure that you have an easier time grasping these sometimes-difficult concepts. If you pay attention to these lessons, by the time you finish the chapter you should have a much better understanding of:

  • The definition, characteristics and examples of a scientific theory
  • Scientific law and related theories
  • The steps and examples of scientific investigation
  • The scientific method
  • Scientific experiments

Each of the lessons contains helpful video tags that will allow you to bookmark and return to the most crucial moments in each video. The chapter also offers hard copies of every lesson for you to study at your own convenience. Once you are comfortable in your knowledge of these topics, you can test yourself by going over the practice quiz questions also contained within the chapter.

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

1. 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.

What is a Scientific Law? - Definition & Examples

2. What is a Scientific Law? - Definition & Examples

In this lesson, you will learn about scientific laws. The topic will be defined for you and several types of scientific laws will be described. Finally, examples of scientific laws and theories will be provided to assist you with learning the difference between the two terms.

How Scientific Observations Lead to Scientific Questioning

3. How Scientific Observations Lead to Scientific Questioning

Scientific observations are a major component of the scientific process because they lead scientists to ask questions about the world around them. These questions may then be refined with continued observation, or they may be tested through experimentation.

What is Scientific Investigation? - Definition, Steps & Examples

4. What is Scientific Investigation? - Definition, Steps & Examples

Scientific investigation is the way in which scientists and researchers use a systematic approach to answer questions about the world around us. Read on to find out more. A quiz is provided to test your understanding.

What is Scientific Research?

5. What is Scientific Research?

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

What Are The Different Kinds of Research Methods?

6. 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

7. 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?

Conducting Scientific Research: Safety Concerns & Regulations

8. Conducting Scientific Research: Safety Concerns & Regulations

When scientists conduct research, safety is a top concern. Learn about the kinds of hazards a scientist faces depending on the kind of work that they do, as well as some risks with scientific research. Plus, see how safety regulations protect all of us.

The Scientific Method: Steps, Terms & Examples

9. 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.

Scientific Experiment: Definition & Examples

10. Scientific Experiment: Definition & Examples

In this lesson, you will learn about the process of a scientific experiment. First, the lesson will outline the definition and give a short history of scientific experimentation. Then the types will be described and, finally, an example of a scientific experiment will be provided.

Scientific Tools and Their Uses

11. Scientific Tools and Their Uses

A scientist relies on tools to help make observations, carry out experiments and take measurements. Learn about the scientific tools used in a lab and the advanced tools used by scientists in the life sciences.

The Dichotomous Key: A Classifying Tool

12. The Dichotomous Key: A Classifying Tool

Sometimes, the best way to identify an object is to take a step-by-step approach. Dichotomous keys are perfect for this, helping us classify unknown objects through a series of questions and answers that lead us down the correct path.

Empirical Data: Definition & Example

13. Empirical Data: Definition & Example

In this lesson, we will explore how empirical data is defined. You will also learn about different types of empirical data and the role empirical data plays in the scientific process.
