Theories may be disproven, of course, but only after rigorous testing of a new hypothesis that seems to contradict them. Even though scientists often record their evidence non-sententially, e.g., in the form of pictures, … 60 seconds . Scientific explanation for a set of observations A hypothesis must be stated in a way that makes it testable. A statement that is extensively tested and generally accepted. Scientific theories continually change over a period of time. It's tested by other scientists to replicate the experiment and confirm the findings. The key steps in the scientific method include the following: Step 1: Make observations. Tags: Question 10 . It's made a scientific law. A scientific theory must explain as many findings as possible. An experiment is a procedure designed to test a hypothesis as part of the scientific method. A hypothesis: a) can be tested, b) is a prediction about the expected outcome of an experiment, c) must be stated in a form that can be either proven or disproven, d) all of the above A) variables The factors in an experiment that can be changed are called: a) variables, b) data, c) the hypothesis, d) the control Step 2: Formulate a hypothesis. Scientific theory: A model that has been repeatedly tested and confirmed may become a scientific theory. This makes it imperative to ask what observation sentences report. For a theory to be accepted, it must first pass the test of experiment and observation not just once but many times. An example of a scientific theory that underwent many changes is the germ theory of disease. Theory testing was treated as a matter of comparing observation sentences describing observations made in natural or laboratory settings to observation sentences that should be true according to the theory to be tested. D. It's put in science textbooks so that students can learn about that theory … The hypothesis is just a possible answer to a question and it must be thoroughly tested. It fits ideas together in a framework. The new results usually show that the accepted ideas were completely wrong. The independent variable is controlled or changed to test its effects on the dependent variable. SURVEY . The word "hypothesis" in science is somewhat closer to the everyday use of the word "theory." A. C. It's accepted by all in the scientific community and no further testing is conducted. If anyone finds a case where all or part of a scientific theory is false, then that theory is either changed or thrown out. The two key variables in any experiment are the independent and dependent variables. These theories have been tested by a number of independent researchers around the world using various experiments, and all have supported the theory. The scientific method is a method of investigation involving experimentation and observation to acquire new knowledge, solve problems, and answer questions. Accepted scientific ideas are usually based on the latest experiments. It's an educated guess about the way reality works, usually based on an interesting experimental result or observation. B. In modern science, a scientific theory is a tested and expanded hypothesis that explains many experiments. Q. A hypothesis is the first step along the path toward a theory.
