In science, an experiment is simply a test of a hypothesis in the scientific method. It is a controlled examination of cause and effect. Here is a look at what a science experiment is (and is not), the key factors in an experiment, examples, and types of experiments. By definition, an experiment is a procedure that tests a hypothesis.
What is an Experiment? An experiment is an investigation in which a hypothesis is scientifically tested. An independent variable (the cause) is manipulated in an experiment, and the dependent variable (the effect) is measured; any extraneous variables are controlled.
: an operation or procedure carried out under controlled conditions in order to discover an unknown effect or law, to test or establish a hypothesis, or to illustrate a known law. Noun Students will carry out simple laboratory experiments. They did some experiments with magnets.
In its simplest form, an experiment is simply the test of a hypothesis. A hypothesis, in turn, is a proposed relationship or explanation of phenomena. The experiment is the foundation of the scientific method, which is a systematic means of exploring the world around you.
An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated.
What Is an Experiment? As we saw earlier in the book, an experiment is a type of study designed specifically to answer the question of whether there is a causal relationship between two variables.
In an experiment, a researcher manipulates one or more variables, while holding all other variables constant. By noting how the manipulated variables affect a response variable, the researcher can test whether a causal relationship exists between the manipulated variables and the response variable.

We use experience as a verb when something happens to us, or we feel it. It is rather formal: … Things would never change if people weren't prepared to experiment. experiment with The school is experimenting with new teaching methods. experiment on Experimenting on mice can give us an idea of the effect of the disease in humans.
What is the Scientific Method? The scientific method is a process for experimentation that is used to explore observations and answer questions. Do all scientists follow the scientific method exactly? No. Some areas of science can be more easily tested than others.
OK, so an experiment is an observation where you do something to test an idea. Instead of just using your senses, you actively cause something to happen. Once you really think about it, you use experiments all the time. Consider the following example: You turn on the television, and nothing happens. You try changing channels.
