1. Three Branches of Natural Science: Physical, Earth & Life
After completing this lesson, you will be able to explain what science is. You will be able to distinguish between the three branches of natural science: physical, Earth and life science.
2. 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.
3. What is Scientific Research?
This lesson will discuss important components of scientific research, including the scientific method, peer review, statistical significance, and more!
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.
5. Developing a Scientific Hypothesis
This video describes how to create a hypothesis and includes the three main things needed to create a strong hypothesis. You'll learn how to make a clear statement that can be both tested and measured.
6. Reading and Interpreting Line Graphs
Watch this video lesson to find out how useful line graphs can be and how much information you can gain just from looking at one. Learn how you can apply that information in your own life to help you make better decisions.
7. 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.
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.
9. Standard Units of Measurement for Length, Weight, Time & Capacity
Watch this video lesson to learn how to recognize the various units of measurement for length, weight, time and volume. Learn to recognize both U.S. units and metric units.
10. Temperature Units: Converting Between Kelvin and Celsius
Have you ever wondered what the lowest possible temperature is? In this lesson, you will learn what temperature measures. You will also be introduced to the Kelvin scale (an absolute scale) and learn how it relates to the Celsius scale.
11. How to Take Measurements with Scales, Meters & Gauges
In the real world, we take measurements all the time. Measurements are taken when you drive and when you weigh yourself, for example. Watch this video lesson to learn how you can take measurements of things that are important.
12. How to Perform Basic Operations with Measurements
In this video lesson, you will learn how measurements are very much like variables when it comes to adding, subtracting, multiplying, and dividing them. You will also see examples of how they are done.
13. Current SI Standards in Science
After completing this lesson, you will be able to explain why standard units are used in science, and list and describe the seven standard SI units scientists use. A short quiz will follow.
14. 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.
15. What Is Density? - Explanation & Examples
After watching this video, you will be able to explain what density is, give examples of high and low density, and calculate density using an equation. A short quiz will follow.
