1. Science Vocabulary & Concepts: Study Skills & Word Parts
Learning science presents a unique set of challenges for students. In this lesson, learn the tricks of the trade as we discuss scientific vocabulary and other science study skills.
2. Identifying & Interpreting Independent & Dependent Variables
Scientists answer questions by performing experiments that have an independent variable, a dependent variable and at least one control variable. By controlling, adjusting and measuring these variables, scientists find answers to their questions.
3. 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.
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. 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.
6. The Metric System: Units and Conversion
Just like you and your friend communicate using the same language, scientists all over the world need to use the same language when reporting the measurements they make. This language is called the metric system. In this lesson we will cover the metric units for length, mass, volume, density and temperature, and also discuss how to convert among them.
7. 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.
8. 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.
9. Understanding Textual & Non-Textual Scientific Presentations
In order to understand science, you have to know science. This knowledge includes understanding the various ways that scientific information may be presented as well as how to critically analyze that information.
10. How to Read Scientific Graphs & Charts
How do scientists summarize their findings with visual aids? In this lesson, explore the different types of tables, charts and graphs that scientists use. Learn to read these effectively as a preview to your science studies.
11. Interpreting Graphs and Charts of Scientific Data: Practice Problems
Do charts and graphs make problem-solving difficult? Complex problems with visual representations can drain your brain during a test. In this lesson, learn three simple rules for solving problems with charts and graphs. We'll try them out as we walk through two sample problems.
12. Interpreting Tables of Scientific Data: Practice Problems
Complex table problems getting you down? Multi-question, situational problems don't have to be a drag on your testing performance. Learn how to apply three simple rules as we walk through two table problems together.
13. Design a Scientific Experiment: Example of Avery and Griffith's Experiment
What are the requirements of a scientific experiment? How do scientists design their investigations? In this lesson, we'll use the work of Avery and Griffith to explore the process of experimental design.
14. Strong Force: Definition, Equation & Examples
In this lesson, you'll learn what strong force is, how it holds an atom together, and how it is balanced by electromagnetic repulsion. A short quiz will follow.
15. Tertiary Structure of Protein: Definition & Overview
Tertiary protein structure turns a simple polypeptide with pretty little ribbons and twists into a big, globular mass. Amino acid side chains are the culprit. Read this lesson to find out why.
16. Test Tube: Function in the Lab & Concept
Test tubes are important pieces of laboratory equipment and have a wide variety of uses in the laboratory. They are very basic in structure, but useful in many different fields of science. This lesson discusses test tubes, their structure, and their functions.
17. The Law of Definite Proportions: Definition & Examples
Have you ever had to double a baking recipe? The trick is to always keep the ingredient proportions the same as in the original recipe. This cooking principle follows the Law of Definite Proportions in chemistry, which is the focus of this lesson.
18. Trajectory: Definition & Equation
In this lesson, we'll explore the science behind ballistic trajectories and the equations for doing some simple calculations. A quiz is provided to help test your knowledge.
19. Volumetric Flask: Uses & Calibration
Volumetric flasks are key pieces of scientific equipment used in laboratories. These flasks are important for experimentation, and this lesson addresses their characteristics and uses in the laboratory environment.

Chemical formulas provide a lot of information about chemical substances, such as how many and what atoms they are made of, as well as the way the atoms are arranged. In this lesson, we'll discuss the different types of chemical formulas.
25. What Is a Chemical Property of Matter? - Definition & Examples
All matter is characterized based on its properties. In this lesson, you will learn about the different chemical properties of matter and ways to identify them.
26. What is Chemistry? - Definition, History & Topics
Chemistry is the science of matter. This may sound simple, but chemistry is a complex and broad topic that broaches a wide variety of fields. From the core of the earth to the farthest reaches of the universe, chemistry is everything and everywhere.
27. What is Inorganic Chemistry? - Definition, Impact Factor & Examples
With this lesson, you will learn the definition of inorganic chemistry. You will also learn the types of inorganic compounds, how they react and their applications in several industry sectors.
28. What Is Scientific Notation? - Definition, Rules & Examples
Scientific notation is part of the language of math and science and allows us to deal with a vast array of numbers, large and small. Learn more about what it is, why it's important, and how to use it.
29. Who was Albert Einstein? - Theory, Facts & Quotes
Albert Einstein was Time Magazine's Person of the Century in 1999 for many good reasons. This lesson takes a quick look at Einstein's life, works, and his influence on the world.
