About This Chapter

Increase your understanding of scientific inquiry and design by working through the lessons in this chapter. With the help of our expert instructors, you can master the scientific investigation topics in this chapter before moving forward to others.

Scientific Inquiry & Design- Chapter Summary

As you work through this chapter, you'll review essential concepts related to scientific inquiry and design. Take a look at scientific questioning, experimental design, and data from experiments. Our lessons also go over the following concepts:

  • Steps involved in scientific investigation
  • Importance of observations to the scientific process
  • Relationship between hypothesis, theory and law in science
  • Difference between a good and bad hypothesis
  • Samples, groups and variables in experiments
  • Different types of processing skills
  • Components of scientific investigations

Our instructors have broken these concepts up into manageable pieces to make them easy for you to understand. You can access these lessons as many times as you'd like until you've mastered these concepts. Test your knowledge with short lesson quizzes and the full chapter exam. If you are having difficulties, our instructors are available to answer any questions that may come up.

What is Scientific Investigation? - Definition, Steps & Examples

1. 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.

How Scientific Observations Lead to Scientific Questioning

2. 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.

Hypothesis, Theory & Law in Science

3. Hypothesis, Theory & Law in Science

In this lesson, learn how to define hypothesis, theory, and law in science. Then, discover the ways that these ideas are related to each other and how they help us to explain the universe around us.

Formulating a Viable Scientific Hypothesis

4. Formulating a Viable Scientific Hypothesis

Constructing a viable scientific hypothesis involves several different factors. In this lesson, you'll explore what separates a good hypothesis from a bad one and how to identify if your hypothesis has been formulated properly.

True Experimental Design

5. 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.

How to Process & Apply Knowledge in Science

6. How to Process & Apply Knowledge in Science

In this lesson you'll be learning about analytical skills that will help you become a better scientist. Here, you'll learn how observing, making comparisons and inferences, generalizing, and applying data can help you reach scientific conclusions.

Scientific Investigations: Data, Evidence & Reasoning

7. Scientific Investigations: Data, Evidence & Reasoning

What is a scientific investigation? And how are data, evidence, and reasoning central to the scientific process? Learn about the difference between data and evidence and why logical reasoning is just as necessary as data itself.
