The Nature of Science

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.

Experimental Design in Science: Definition & Method

2. 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.

What is Critical Thinking? - Definition, Skills & Meaning

3. What is Critical Thinking? - Definition, Skills & Meaning

Critical thinking is a term that we hear a lot, but many people don't really stop to think about what it means or how to use it. This lesson will tell you exactly what it means and make you realize that the average person largely ignores critical thinking.

The Scientific Method: Steps, Terms & Examples

4. 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.

How to Convert Units in the Metric System

5. How to Convert Units in the Metric System

If you can make dinner, you can convert units in the metric system. It's that easy! In this lesson, you'll learn about the three key things you'll need to perform conversions.

The Metric System: Units and Conversion

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.

Using Visuals to Present Data: Textual Graphics vs. Visual Graphics

7. Using Visuals to Present Data: Textual Graphics vs. Visual Graphics

Textual and visual graphics can aid in visually presenting data to a business audience. You must first identify the type of data you will be presenting and then decide whether it is details, patterns or relationships being communicated.

Interpreting Graphical Representations

8. Interpreting Graphical Representations

After watching this video lesson, you will be able to quickly and easily read and interpret any line and bar graph. You will be able to gather important information by just looking at one of these graphs.

Understanding Bar Graphs and Pie Charts

9. Understanding Bar Graphs and Pie Charts

In this lesson, we will examine two of the most widely used types of graphs: bar graphs and pie charts. These two graphs can provide the reader with a comparison of the different data that is displayed.

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.

Scientific Notation: Practice Problems

11. Scientific Notation: Practice Problems

Scientific notation has a lot of exponents, but it's really not that bad - and it's really convenient for working with awkwardly big or small numbers! Get some practice here.

Evaluating Data: Precision, Accuracy & Error

12. Evaluating Data: Precision, Accuracy & Error

The data you present as a scientist needs to be as accurate, precise and error-free as possible. In this lesson, we'll discuss what each of these terms means, as well as how error is introduced into measurements and other data collection.
