Document Summary
Proposing a hypothesis (based upon the observations made) An experiment is a set of steps (procedures) that are performed under controlled conditions to propose or test a hypothesis. Observations (a key factor in scientific studies as well as in everyday life) can be classified as: A hypothesis is a tentative explanation to account for the observations of an experiment. A hypothesis is valid provided that one"s assumptions to explain the observations of an experiment can be tested. The validity of the hypothesis needs to be confirmed via repeated and controlled experiments. In order to accept a hypothesis, there must be no inconsistencies between the hypothesis and the experimental observations. In the even of any inconsistencies, steps 1 through 4 must be repeated. By repeatedly performing experiments and modifying the hypothesis to account for the observations from these experiments, one is able to propose a scientific law.
