Ch 23: Scientific Inquiry & Experimentation

About This Chapter

Rediscover what you may have learned about scientific inquiry and experimentation by going through this chapter. Whether you need a quick recap or a full review, the definitions, major concepts, and scientific theories in these lessons will get you up to speed.

Scientific Inquiry & Experimentation - Chapter Summary

It is difficult to have a strong grasp on the sciences without a firm foundation, and this chapter has been built to help you strengthen your fundamental knowledge of scientific inquiry and experimentation. Our experts divided this chapter into small, manageable lessons that each address different aspects about experimental design and the scientific method. As you move through the lessons, you'll gain the skills necessary to be able to:

  • Detail the terms and steps of the scientific method
  • Establish the definition for a scientific experiment
  • Outline moderator, extraneous, control, independent, and dependent variables
  • Evaluate the risks involved with scientific experiments and establish safety precautions
  • Relate out the standards and importance of STEM education
  • Discuss similarities and connections between systems in technology, science, and mathematics
  • Describe the engineering design cycle and related steps

Many of our users worry about having enough time to study this information before taking a major exam. We understand that scheduling your study sessions can be difficult as a working adult, so we do everything we can to make the process easier on you. For starters, we break up every chapter into shorter, self-contained lessons. You can usually get through any one of these lessons in less than eight minutes. That way, even if you only have short windows of time to study throughout the day, you can still make steady progress and reach your study goals.

The Scientific Method: Steps, Terms & Examples

1. 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

2. 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.

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

3. 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?

Understanding Risks & Taking Safety Precautions in Science Experiments

4. Understanding Risks & Taking Safety Precautions in Science Experiments

An important step in designing your experiment involves identifying and evaluating any potential safety risks. Knowing what these risks are ahead of time can help you avoid accidents and dangerous situations, which helps keep the experiment safe and fun for all.

What Is STEM Education? - Definition, Importance & Standards

5. What Is STEM Education? - Definition, Importance & Standards

STEM stands for science, technology, engineering, and math. Learn more about what STEM education is, why it is important and explore standards associated with STEM. A short quiz follows the lesson.

Similarities Among Systems in Mathematics, Science & Technology

6. Similarities Among Systems in Mathematics, Science & Technology

How do the concepts of balance and equilibrium extend throughout science and mathematics? How does solving algebraic equations parallel chemical equilibrium within a solution? See how crucial balance is in our universe as well as how mathematics is used to describe these constant equilibriums.

Steps of the Engineering Design Cycle

7. Steps of the Engineering Design Cycle

Learn about the steps an engineer takes to design, build, and optimize a product, also called the engineering design cycle. See what you've picked up with a quiz.
