What is Scientific Investigation? - Definition, Steps & Examples

1. What is Scientific Investigation? - Definition, Steps & Examples

Scientific investigation is the way in which scientists and researchers use a systematic approach to answer questions about the world around us. Read on to find out more. A quiz is provided to test your understanding.

Hypothesis, Theory & Law in Science

2. Hypothesis, Theory & Law in Science

In this lesson, learn how to define hypothesis, theory, and law in science. Then, discover the ways that these ideas are related to each other and how they help us to explain the universe around us.

True Experimental Design

3. True Experimental Design

Experiments are the classic way to conduct research in almost any field of study. But do you know how true experiments really work? This lesson explains the details of experimental design, such as different types of samples, control groups and independent vs. dependent variables.

Identifying Sources of Unavoidable Experimental Error

4. Identifying Sources of Unavoidable Experimental Error

Good data are essential for any experiment. But no matter how hard you try, error in your data is unavoidable. In this lesson, you'll learn about the types of unavoidable experimental error to be on the lookout for and how to reduce their occurrence in your data.

The Nature of Science

5. 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.

How to Interpret Scientific Evidence

6. How to Interpret Scientific Evidence

Watch this video lesson to learn how you can tell whether or not your scientific data answers your question by determining what your data is telling you. Then test your new knowledge with a quiz!

Fundamental Scientific Concepts: Patterns, Structure, & Function

7. Fundamental Scientific Concepts: Patterns, Structure, & Function

In this lesson we'll be looking at some basic concepts that run concurrently through all disciplines in science: patterns, structure and function. We'll discuss what each of these concepts mean and apply them to life, physical and Earth science.
