About This Chapter
Introduction to Scientific Inquiry - Chapter Summary
Whether you're looking to brush up on scientific inquiry concepts you haven't studied in a while or fill gaps in your current knowledge, we have you covered! Lessons in this chapter closely examine the nature of science, scientific notation, sampling techniques in scientific investigations, controlled tests in scientific research and more! After you've finished this chapter, you will be able to:
- Define and list the steps of scientific investigation
- Organize data with graphs and charts
- Evaluate and present data from scientific investigations
- Discuss whether given evidence supports conclusions
- Detail the risks of scientific experiments and how to take safety precautions
- Share ways to use appropriate tools for scientific tests and data collection
- Exhibit knowledge of unit conversion and dimensional analysis

This chapter's self-paced format enables you to choose the lessons you want to study, navigate in any order and visit as often as you'd like. But that's not all! Around-the-clock computer and mobile access lets you explore the lessons during times you desire using your preferred computer, smartphone or tablet. Mini quizzes and a practice exam can quickly test your knowledge of key lesson concepts and confirm your readiness for exam day. The dashboard tracks your progress and lets you submit any lesson topic questions to our subject-matter experts.
1. The Nature of Science
This lesson will explore the basic nature of science. It will distinguish science from pseudoscience and hypothesis from theory and natural law; it will give plenty of examples of each.
2. 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.
3. Importance of Controlled Tests in Scientific Research
One way to ensure that your experimental results are meaningful and relevant is to control for factors that may affect your experiment. In this lesson, we'll talk about how to do this and why it's so important in scientific research.
4. Sampling Techniques In Scientific Investigations
We can learn a lot by gathering information from a small subset of a larger group. By sampling this smaller group, scientists can save time and money while still gaining a good understanding of the population as a whole.
5. How to Organize Data with Charts & Graphs
Research is only valuable if you can share the data effectively. In this lesson, we'll learn how to organize data and construct various charts and graphs to represent research data.
6. 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.
7. Presenting Data from Scientific Investigations
In this lesson we'll overview the best practices for presenting data from scientific investigations. We'll talk about how to select appropriate media, cite sources, and use symbols, equations, pictures, and graphs in your presentations.
8. Understanding Whether Given Evidence Supports a Conclusion
Part of being a good scientist is evaluating other scientists' work. One aspect of this is knowing whether the evidence provided supports the scientists' conclusions. While this is not always easy, it is necessary in order to produce good science.
9. 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.
10. Using Appropriate Tools for Scientific Tests & Data Collection
A properly run experiment depends on using the right tools, both for data collection and analysis. In the end, it will save you time, money and frustration to spend some time planning out which tools are most appropriate for your work.
11. Unit Conversion and Dimensional Analysis
How is solving a chemistry problem like playing dominoes? Watch this lesson to find out how you can use your domino skills to solve almost any chemistry problem.
12. Scientific Notation: Definition and Examples
Scientific notation is a special way of writing numbers so they are easier to work with. This lesson will define scientific notations and show some examples of how to convert numbers from standard notation to scientific notation and back.
13. Solve for Unknowns in Scientific Equations
Calculating a missing value in an equation is something you may come across in your scientific analyses. As long as you know the relationship between the variables in the equation, as well as the rest of the measured values, this is a relatively straightforward process for you to master.
