Question

describe the features of a laboratory experiment

Answer 1

Laboratory experiments take place in controlled environments and are the main method used in the natural sciences such as Physics, Chemistry and Biology. There are numerous experiments which have been designed to test numerous scientific theories about the temperatures at which various substances freeze or melt, or how different chemicals react when they are combined under certain conditions.

The logic of the experimental method is that it is a controlled environment which enables the scientist to measure precisely the effects of independent variables on dependent variables, thus establishing cause and effect relationships. This in turn enables them to make predictions about how the dependent variable will act in the future.
