Ch 4: Scientific Theories & Investigations

About This Chapter

This chapter's text and video lessons will teach you important topics relevant to scientific theories and investigations. Go over these lessons to learn the basic elements, methods and applications of theories in science.

Scientific Theories & Investigations - Chapter Summary

Despite their often complex and esoteric findings, all scientific fields really boil down to a few basic processes related to scientific investigations and the construction of scientific theories. You can learn more about science by watching or reading the video and text lessons included in this chapter, each of which is dedicated to a specific topic needed to understand theory and investigation in science.

All lessons in this chapter break down a specific aspect of scientific theories, methodologies and analysis in a clear and comprehensive format. Our lesson instructors use their expertise on these topics to ensure that you come away from this chapter with a much better understanding of how scientists investigate data and construct theories. Some of the specific topics you will learn about are:

  • The definition, characteristics and examples of scientific theories
  • The definition and examples of scientific models
  • The observation of changes in natural phenomena
  • How to develop a scientific hypothesis
  • Applications of the scientific method to environmental problems
  • Technology in scientific experiments and analysis
  • How to evaluate data from scientific investigations
  • How to evaluate scientific claims and arguments

Once you have completed each of the lessons, you can test your understanding of these topics by answering the questions found in the chapter's practice quizzes and final exam. You can also get further information on different topics by messaging the lesson instructors directly. Finally, use your personal Dashboard to keep track of your learning progress as you go through the chapter.
