Making a Hypothesis
In making an inference the scientist has built up a hypothesis. A hypothesis is only a best guess. It must next be tested.
If it is correct, then certain things should follow. This means if a particular experiment is carried out, certain observations ought to be possible or it should be possible to make certain predictions.
(If)Should the observations or predictions turn out to be as expected, the scientist has added confidence in the probable truth of his hypothesis. If, however, observations cannot be made or the predictions are unreliable, then the hypothesis will probably be given up or at least modified.
The Experiment
The hypothesis must check with(agree with) the facts. Scientific facts are usually established by work in the laboratory. Experiments have to be made under carefully controlled conditions. Thorough and accurate records must be kept.
In making certain kinds of experiments in science variables are used. A variable is something which has different values under different conditions. In one type of laboratory test all the variables but one are controlled. This method of testing is called controlled experimentation.
