About This Chapter
Scientific Inquiry - Chapter Summary
Our instructors for this chapter delve into the major terms, concepts and principles that guide scientific inquiry. By watching the entertaining video lessons, you'll learn about the key characteristics of scientific research. You will examine the importance of strong critical thinking skills when working in science, as these are essential to understand and interpret scientific evidence and theories. After viewing all of the videos in the chapter, you should be able to:
- Distinguish between laws, theories, predictions and hypotheses
- Identify the uses and limitations of evidence in scientific model development
- Explain the scientific response to an experiment's unexpected observations or results
- Understand the importance of reproducible data in scientific experiments
- Explain how scientists avoid biases in experiments
- Describe the criteria used to judge scientific theories
- Understand the importance of skepticism, curiosity and honesty in the scientific process
To help you grasp the major concepts and terminology of this chapter, we offer a number of features with our lessons. A lesson transcript is attached to each lesson with key terms highlighted in bold. Videos include a jump feature in the timeline so that you can rewatch certain excerpts without having to replay the entire video. Once you think you've got a solid understanding of the covered material, you can take self-assessment quizzes to check your comprehension of scientific inquiry concepts.
1. What is Scientific Research?
This lesson will discuss important components of scientific research, including the scientific method, peer review, statistical significance, and more!
2. 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.
3. When Observations Differ From Accepted Scientific Theory
Science is the process of observing the world and trying to explain and predict what will happen. Often, as more information becomes available, the accepted scientific theories must change.
4. How to Avoid Bias in Scientific Investigations
In this lesson, you will learn what it takes to conduct a proper scientific investigation while doing your best to avoid any possibility of bias. Learn where possible sources of bias can come from and what you can do about it.
5. What is Critical Thinking? - Definition, Skills & Meaning
Critical thinking is a term that we hear a lot, but many people don't really stop to think about what it means or how to use it. This lesson will tell you exactly what it means and make you realize that the average person largely ignores critical thinking.
6. Unexpected Observations & Results in Experiments
Observations and experimental results do not always agree with what we expect. However, these results are not necessarily mistakes, and in this lesson we'll take a look at how they can even lead to useful discoveries.
