1. What is Earth Science?
Earth science is a field that includes geology, astronomy, meteorology, and oceanography. Scientists do research in these fields to discover past and future events. Learn about the dynamic field of earth science and how it affects our lives in this lesson.
2. What Are Life Sciences?
The life sciences study all types of living things. Branches of the life science study things from the tiniest microorganisms to the largest animals. Learn about the many branches of the life sciences and what it's like to work in these fields.
3. The Main Branches and Sub-Branches of Physical Science
The physical sciences study non-living things. That is a lot of stuff! In the physical sciences, you might study the earth, air or space. Learn about the two main branches, physics and chemistry, as well as sub-branches, like geology and meteorology.
4. What is the Scientific Theory? - Definition, Characteristics & Example
In this lesson, you'll learn the definition and characteristics of a scientific theory and understand how theories are formulated. You'll see examples of scientific theories, and after the lesson you can test your knowledge with a brief quiz.
5. What is a Scientific Law? - Definition & Examples
In this lesson, you will learn about scientific laws. The topic will be defined for you and several types of scientific laws will be described. Finally, examples of scientific laws and theories will be provided to assist you with learning the difference between the two terms.
6. How Scientists Gather Evidence
How do scientists gather evidence? Learn why empirical evidence is important in science, and see if you can evidence what you've learned by taking a quiz.
7. How Scientific Ideas Change
How do scientific ideas change? Where do they come from? Learn how those ideas spread among scientists, and then among the general public. Take a quiz to see how well the ideas in these lessons have spread.
