About This Chapter
Virginia SOL Chemistry: Experiments & Data- Chapter Summary
The Virginia Standards of Learning (SOL) exam on chemistry may contain questions that will assess you on the subject of experiments and data in the field of chemistry. Prepare for these questions by going over this chapter's lessons and quizzes. The lessons will go over topics such as:
- The definition and examples of true experiments
- The definition and purpose of repeated trials
- The nature of science
- The scientific point of view
- Linear equations
- The different parts of a graph
- Ratios and proportions
The chapter's lively lessons, multiple-choice quizzes and video timelines will help you familiarize yourself with what you can expect on the actual Virginia SOL chemistry exam. As a result, you can find yourself in a much better position to do well on the exam if you let us assist you in your preparation!
1. True Experiment: Definition & Examples
A true experiment is thought to be the most accurate experimental research design. Learn more about true experiments from examples and test your knowledge with a quiz.
2. Repeated Trials: Definition & Purpose
Repeated trials make the data you collect in experiments more reliable. Learn what repeated trials are, and find out how to record, organize, and analyze them.
3. Identifying Sources of Unavoidable Experimental Error
Good data are essential for any experiment. But no matter how hard you try, error in your data is unavoidable. In this lesson, you'll learn about the types of unavoidable experimental error to be on the lookout for and how to reduce their occurrence in your data.
4. 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.
5. Scientific Point of View: Construction & Defense
Everyone has an opinion, but scientific viewpoints are far more reliable because they're based on evidence. Learn how to construct and defend a scientific viewpoint using logic and the scientific literature.
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. Elements of the SI: Base & Derived Units
Discover what we mean by SI units. Then explore SI units further by learning about all the base units, and several examples of the derived units that make up the system.
8. What is a Linear Equation?
Most cars won't be able to run for more than 250,000 miles, so how much longer will your car live? Linear Equations are the most basic kind of algebraic function and can help you answer questions exactly like this. Learn about what they look like, how they come up in your life and why they are powerful tools.
9. What Are the Different Parts of a Graph?
Being able to read a graph isn't just vital for an algebra class. Graphs and charts are used everywhere! We'll take a crash course on the basic x/y plane used in algebra and the fundamental vocab you need.
10. Slopes and Rate of Change
If you throw a ball straight up, there will be a point when it stops moving for an instant before coming back down. Consider this as we study the rate of change of human cannonballs in this lesson.
11. Ratios and Proportions: Definition and Examples
Watch this video lesson to learn how ratios and proportions are related. Also, learn how ratios and proportions are used in real life and how you can apply them to yours.
12. 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.
13. Using Technology to Gather, Communicate & Model Scientific Data
In this lesson, we discuss how technology can be used to gather, interpret and present scientific data. Specifically, we discuss the use of computers and graphing calculators, probes, and simulations.
