What is Chemistry? - Definition, History & Branches

1. What is Chemistry? - Definition, History & Branches

Known as the central science, chemistry is integral to our understanding of the natural world around us. In this lesson, you'll be introduced to the field of chemistry, learning about its history and its modern applications.

The Scientific Method: Steps, Terms & Examples

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.

Using Appropriate Tools for Scientific Tests & Data Collection

3. 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.

Sampling Techniques In Scientific Investigations

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.

Interpreting Tables of Scientific Data: Practice Problems

5. 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.

Interpreting Graphs and Charts of Scientific Data: Practice Problems

6. 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.

Measurements & Uncertainty in Science

7. Measurements & Uncertainty in Science

In this lesson, you will discover the importance of precision and accuracy in science while learning to make measurements. Also, you will understand how to perform calculations with measurements that conserve precision and limit uncertainty.

The Metric System: Units and Conversion

8. 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.

Unit Conversion and Dimensional Analysis

9. 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.

Significant Figures and Scientific Notation

10. 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.

Measuring Temperature in the Lab: Instruments & Process

11. Measuring Temperature in the Lab: Instruments & Process

In this lesson, discover what temperature is a measurement of while learning how to properly measure temperature in a lab. Learn about the important instruments needed for this essential lab skill.

Chemistry Lab Safety & Accuracy Procedures & Equipment

12. Chemistry Lab Safety & Accuracy Procedures & Equipment

Working safely and collecting accurate data are the two most important parts of working in a chemistry lab. This lesson will give tips so you can succeed in both areas.

Chemistry Lab Equipment: Supplies, Glassware & More

13. Chemistry Lab Equipment: Supplies, Glassware & More

When you bake a cake, you use different tools for each step in the process: a bowl for mixing, cups for measuring ingredients and an oven for baking. In this lesson, you will discover the name and purpose of many of the different tools that are used in the chemistry lab.
