Physics is an experimental science.The premise of the scientific method is that (observation of) nature is the ultimate judge of the truth of any physical theory. Indeed, experiments designed to prove certain ideas have often ended up showing them to be wrong.A laboratory is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed.
A laboratory experiment is an experiment conducted under highly controlled conditions. The variable which is being manipulated by the researcher is called the independent variable and the dependent variable is the change in behaviour measured by the researcher.
Laboratory safety is of paramount importance to Environmental Health & Safety, which manages and responds to all issues and concerns surrounding chemical, biological, radiation, laser, chemical fume hood, and centrifuge safety as well as biological safety cabinets, compressed gas cylinders, nanotechnology and emergency.A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable. This increases the reliability of the results, often through a comparison between control measurements and the other measurements.
