About This Chapter
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.
1. 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.
2. Scientific Models: Definition & Examples
What are scientific models and how are they used? Learn about the different types of scientific models, including visual, mathematical, and computer models, and discover some real-life examples of each.
3. Observing Changes in Natural Phenomena Over Time
Science is all about observing changes - even when they are difficult to observe. Learn about how scientists observe changes in natural phenomena over time. Test your knowledge after the lesson with a quiz.
4. Developing a Scientific Hypothesis
This video describes how to create a hypothesis and includes the three main things needed to create a strong hypothesis. You'll learn how to make a clear statement that can be both tested and measured.
5. The Scientific Method Applied to Environmental Problems: Definition, Steps and Applications
In this lesson we will investigate the steps involved in the scientific method. We will also explore how the scientific method is used to solve environmental problems.
6. Using Technology in Scientific Experiments & Analysis
How is technology used in scientific experiments? How is it used to analyze data? Learn about how science and technology are related, and then take a quiz to see what you've picked up.
7. Evaluating Data from Scientific Investigation
After watching this video, you will be able to explain the meaning of the terms 'accuracy' and 'reproducibility,' or precision, as they relate to science experiments. A short quiz will follow.
8. 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.
