# Scientific Method

Learn about the scientific method. Get the steps to the scientific method, explanations of different types of variables and learn how to design an experiment using the scientific method.

The Scientific Method
Science fair and research projects apply the scientific method. Here's an informal explanation of the scientific method and how it is used.

Scientific Method Flow Chart
This flow chart diagrams the steps of the scientific method.

Science Flowchart
This flowchart diagrams the interaction and collaboration that is a part of how real scientists apply the scientific method.

Scientific Method Quiz
Do you really understand what the scientific method is and how to apply it? Here's a ten question multiple choice quiz you can take to test your knowledge.

Scientific Method Quiz #2
Test how well you understand the scientific method with this fun multiple choice quiz.

What Is an Experiment?
Here's an explanation of what an experiment is and how experimentation ties in with the scientific method.

What Is a Hypothesis?
Learn what a hypothesis is in science and how to formulate a hypothesis and apply it to the scientific method.

What Are Examples of a Hypothesis?
A hypothesis is an educated guess or scientific explanation of observations, used as part of the scientific method. Here are examples of a scientific hypothesis.

What Is a Variable in Science?
Variables are an important part of science projects and experiments. Here is an explanation of what a variable is and the types of variables you'll encounter in science.

What is a Dependent Variable?
A dependent variable is the variable being tested in a scientific experiment.

What is an Independent Variable?
An independent variable in a scientific experiment is the variable that is changed to test the effect on a dependent variable.

What is the Difference Between Independent and Dependent Variables?
The difference between independent and dependent variables in a scientific experiment is which variable is being measured.

What Is a Control Group?
A control group in a scientific experiment is a group separated from the rest of the experiment where the independent variable being tested cannot influence the results.

What Is an Experimental Group?
An experimental group in a scientific experiment is the group where the experimental procedures are performed.

What is the Difference Between Control Group and Experimental Group?
The difference between a control group and an experimental group is one group is exposed to the conditions of the experiment and the other is not.

How to Write a Lab Report
Lab reports are an essential part of all laboratory courses and usually a significant part of your grade. If your instructor gives you an outline for how to write a lab report, use that. Here's a format for a lab report you can use if you aren't sure what to write or need an explanation of what to include in the different parts of the report.

Scientific Law, Hypothesis, Theory Definitions
Words have very specific meanings in chemistry and other sciences. Learn about the difference between a scientific law, hypothesis, and theory. Examples are provided for each term.

What Is a Controlled Experiment?
One of the most common types of experiment is a controlled experiment. Here is a look at what a controlled experiment is and why this type of experiment is so popular.

Controlled Variable Definition
Learn what a controlled variable or constant variable is.

What Is an Experimental Constant?
Learn about the types of experimental constants and get examples of constants.

DRY MIX Experimental Variables Acronym
Learn how to use the acronym DRY MIX to remember what the independent and dependent variables are and where to put them on a graph of experimental data.

What Is the Difference Between a Control Variable and Control Group?
Learn about the difference between a control group and a control variable.

Simple Experiments Versus Controlled Experiment
Learn what a simple experiment is, the difference between a simple experiment and a controlled experiment, and get examples of simple and controlled experiments.

Science Experiment Glossary - Experiment Terms
Scientific experiments involve variables, controls, a hypothesis, and a host of other concepts and terms that may be confusing. This is a glossary of important science experiment terms and definitions.

How To Design a Science Fair Experiment
These are steps to design a science fair experiment using the scientific method.
