Experimental science

Experimental science is science based on experimental research that plays the role of testing hypothesis, typically in controlled laboratory settings. The hypothesis investigated in classical experimental science postulate regularities among event-types. These regularities may be statistical, as in quantum mechanics, and they may or may not be causal. Experimental scientists are interested in testing functional regularities (e.g. the Boyle-Charles's law for ideal gases), as well as causal regularities. A test condition C is inferred from the hypothesis and a prediction is made about what should happen if C is realized. This forms the basis for a series of controlled experiments.

If experiments continue to be successful in testing the predictive power of hypothesis, then there might be enough amount of scientific evidence to back up the hypothesis to the degree that it eventually becomes accepted as scientific theory. An experiment is a procedure carried out to support, refute, or validate a hypothesis. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale, but always rely on repeatable procedure and logical analysis of the results. There also exists natural experimental studies. A child may carry out basic experiments to understand gravity, while teams of scientists may take years of systematic investigation to advance their understanding of a phenomenon. Experiments and other types of hands-on activities are very important to student learning in the science classroom.

Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time. Experiments can vary from personal and informal natural comparisons (e.g. tasting a range of chocolates to find a favorite), to highly controlled (e.g. tests requiring complex apparatus overseen by many scientists that hope to discover information about subatomic particles). Uses of experiments vary considerably between the natural and human sciences
