About This Chapter
TExES Chemistry: Scientific Inquiry & Processes - Chapter Summary
Use the lessons in this chapter to go over general research practices, scientific research methods, scientific ethics and science history. Specific topics covered include the history of science, the influences on science, applying ethics to scientific investigations and risk-benefit analysis. You'll also study the formula for probability, the relationship between science and technology and how they can both be used to solve society's problems. This type of knowledge is important to middle and high school science teachers and is measured during the TExES Chemistry 7-12 exam. Once you have reviewed the lessons, you should be able to:
- Define scientific research
- Outline the scientific method, including terms, steps and examples
- Detail the methods used in scientific experimental design
- Differentiate between qualitative and quantitative data in various research methods
- Interpret graphs, charts and tables of scientific data
- Identify significant figures and scientific notation
- Assess the quality of a research study
- Unify concepts common to all sciences
Video lessons are short and easy to follow, making review of the material simple and fun. Quizzes corresponding to each lesson allow you to assess your understanding of the topics in the same multiple-choice format you will encounter on the actual TExES Chemistry exam. Print out the lesson transcripts for handy study guides you can review offline anytime.
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. 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.
3. Experimental Design in Science: Definition & Method
What are the requirements of a scientific experiment? How do scientists turn hypotheses into theories and laws? Learn the answers to these questions and more in this lesson on the design of scientific experiments.
4. Qualitative vs. Quantitative Data in Various Research Methods
Qualitative data and quantitative data are both useful in research, but it is important to understand the differences between the two. Learn how to differentiate the two types of data in this lesson.
5. How to Interpret Tables, Graphs & Charts of Scientific Data: Practice Problems
In this lesson, we will look at some practice problems involving tables, graph, and charts. We will specifically look at x- and y-axis graphs, pie charts, and bar graphs.
6. Significant Figures and Scientific Notation
Are 7.5 grams and 7.50 grams the same? How do scientists represent very large and very small quantities? Find out the answers to these questions in this video.
7. Validity and Reliability: How to Assess the Quality of a Research Study
Many psychologists and teachers complete research studies. How can you tell if a study was done well? This lesson will cover many criteria for a good quality study, including types of reliability and validity.
8. Unifying Concepts Common to All Sciences
After completing this lesson, you will be able to explain what science is and describe some concepts and ideas that are common across all sciences. A short quiz will follow.
9. The History of Science: Events, Contributions & Theories
In this lesson, we discuss a few significant events in science's history. We will see how science has changed over the years as we start to question what we think we know.
10. The Influences on Science as a Human Endeavor
Science is loved by many and criticized by some. What is there to love and dislike about it? This lesson answers this question from a personal, cultural, and global standpoint.
11. Applying Ethics to Scientific Investigations
In this lesson we will learn about ethics in science. We will look at why ethics is important and consider a few examples of how scientists need to act ethically in their experiments.
12. Risk-Benefit Analysis: Definition & Example
What is a risk-benefit analysis? Learn about the information and steps needed to complete a risk-benefit analysis, and go through an example of how it's used in medicine.
13. Introduction to Probability: Formula & Examples
Ever taken a chance on something? Before you took that chance, did you want to know what your chances were on actually winning? Then you were dealing with probability, the likelihood that a specific event will occur.
14. How Science & Technology Are Related
What are science and technology, and how are they related? Learn about how science leads to technology, and technology leads to science. Discover some examples from history.
15. How Science & Technology Can Be Used to Solve Society's Problems
What is science and technology, and how do we use them to solve society's problems? Learn about the many advances humans have made thanks to science, then test your knowledge with a quiz.
