Ch 1: Process of Scientific Inquiry

About This Chapter

Go over the key components of scientific inquiry with this chapter. You'll find lessons concentrating on the characteristics of a scientific theory and the varieties of research methods.

Process of Scientific Inquiry - Chapter Summary

This chapter breaks down key components of scientific research, including the definition of research, types of research methods, an explanation of the scientific theory, and examples of scientific experiments. After finishing the chapter, you should be able to:

  • Define experimental design in science
  • Detail research variables, how to formulate a research hypothesis and the the null hypothesis
  • Explain sampling and data collection techniques
  • Present data from investigations
  • Identify appropriate tools for tests and data collection
  • Assess the validity of scientific sources, claims and arguments
  • Discuss researcher variables that affect internal validity

Each of these topics are presented in short, fun video lessons. You can easily reexamine specific parts of the videos using the video tags. The practice quizzes throughout the chapter incorporate the major points of the lessons and assess your expertise of the subject matter.

What is Scientific Research?

1. What is Scientific Research?

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

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

2. 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.

Scientific Experiment: Definition & Examples

3. 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.

Experimental Design in Science: Definition & Method

4. Experimental Design in Science: Definition & Method

What are the requirements of a scientific experiment? How do scientists turn hypotheses into theories and laws? Learn the answers to these questions and more in this lesson on the design of scientific experiments.

What Are The Different Kinds of Research Methods?

5. 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

6. 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?

Formulating the Research Hypothesis and Null Hypothesis

7. Formulating the Research Hypothesis and Null Hypothesis

After figuring out what you want to study, what is the next step in designing a research experiment? You, the researcher, write a hypothesis and null hypothesis. This lesson explores the process and terminology used in writing a hypothesis and null hypothesis.

Sampling Techniques In Scientific Investigations

8. 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.

Strategies for Choosing a Data Collection Technique

9. Strategies for Choosing a Data Collection Technique

After figuring out what you are going to study, you, as the researcher, will need to figure out how to study it. This lesson discusses popular ways a researcher can collect data as well as why a researcher would chose a particular data collection technique.

Using Appropriate Tools for Scientific Tests & Data Collection

10. Using Appropriate Tools for Scientific Tests & Data Collection

A properly run experiment depends on using the right tools, both for data collection and analysis. In the end, it will save you time, money and frustration to spend some time planning out which tools are most appropriate for your work.

Presenting Data from Scientific Investigations

11. Presenting Data from Scientific Investigations

In this lesson we'll overview the best practices for presenting data from scientific investigations. We'll talk about how to select appropriate media, cite sources, and use symbols, equations, pictures, and graphs in your presentations.

Scientific Sources: Accuracy, Reliability & Validity

12. Scientific Sources: Accuracy, Reliability & Validity

It's important to use other sources to support your work, but what's even more important is to use the right ones. Sources should be valid, reliable, and accurate, but it's not always easy to tell which ones meet these criteria.

How to Evaluate Scientific Claims & Arguments

13. How to Evaluate Scientific Claims & Arguments

When you hear about the new scientific discovery, how can you be sure that it's true? Learn how to evaluate scientific claims and arguments, and then test your new skills with a quiz.

Researcher Variables that Affect Internal Validity

14. Researcher Variables that Affect Internal Validity

Scientists want only the independent variable to affect the outcome of their studies, but sometimes it is the things they do themselves that change the outcome. We'll look at three common researcher-related variables: researcher bias, selection bias, and researcher personality in this lesson.
