All of these are examples of hypotheses because they use the tentative word "may." However, their form in not particularly useful. Using the word does not suggest how you would go about proving it. If these statements had not been written carefully, they may not have been a hypotheses at all.
What we publish: Hypothesis invites authors to submit new and thought-provoking predictions based on scientific findings or theories from any field. We aim to establish an interdisciplinary journal that swiftly publishes new, provocative, and sometimes currently untestable ideas, while preserving the free-thinking nature of the earliest scientific publications. Thus, Hypothesis favours publication of articles that go beyond reporting data or summarising a body of work, providing a vessel for thoughtful speculation and healthy debate where authors can freely articulate their most exciting ideas. Moreover, by challenging authors to create intriguing hypotheses concerning their reviewed or original research, Hypothesis is committed to publishing entertaining articles suitable for all readers.
Who we are: The Hypothesis is a global network of academics. Most journal activities, including evaluating manuscripts and handling the external review process, are done on a volunteer basis by members of this academic team. Hypothesis is thus able to maintain an open-access publication model without charging any publication fees, all whilst adhering to a strict external process of peer-review. The journal thus helps level the playing field for researchers around the world, irrespective of local infrastructure or financial resources.
Mission: To elicit healthy scientific thought by disseminating stimulating and novel scientific progress and hypotheses in any field.
In a hypothesis statement, students make a prediction about what they think will happen or is happening in their experiment. They try to answer their question or problem.
Your hypothesis statement will be turned in during science class, reviewed by the teacher and returned. Below is a short explanation of a hypothesis statement and some examples of hypothesis statements.
The word believe does belong to common language. But it is not used in scientific validations of facts and theories.
The scientific method is limited to those phenomenawhich can be observed or measured. For example, what existed priorto the Big Bang and the known universe is outside of the realm of scienceto investigate.
Below is a generalized sequence of steps taken toestablish a scientific theory: The classic scientific method where a convenientlaboratory experiment may be devised and observed often cannot be donein the earth sciences. This is because most of earth and geologicalphenomena are too big (earthquakes, volcanic eruptions) or too slow (mountainbuilding, climate change) to be observed easily or replicated; the earthitself is the "laboratory." Also, because many of the eventsanalyzed by geologists occurred long ago, they often "working backwards"- that is, they start with the conclusion (a rock or fossil), and try towork out the sequence of past events that occurred over geologic time.
A successful scientific inquiry may culminate ina well-tested, well-documented explanation () thatis supported overwhelmingly by valid data, and often has the power to predictthe outcome of certain scenarios, which may be tested by future experiments. There are rare examples of scientific theories that have successfully survivedall known attacks for a very long time, and are called scientific laws,such as Newton's Law of Gravity.
Earth Science The attempts to explainthe natural occurrences () of the universe by usinga logical, consistent, systematic method of investigation, information() collection, data analysis (),testing (), and refinement to arrive at a well-tested,well-documented, explanation that is well-supported by evidence, calleda . The process of establishing anew scientific theory is necessarily a grueling one; new theories mustsurvive an adverse gauntlet of skeptics who are experts in their particulararea of science; the original theory may then need to be revised to satisfythose objections. The typical way in which new scientific ideas aredebated are through refereed scientific journals, such as Nature and ScientificAmerican. (Depending upon the area of science, there are many otherjournals specific to their respective fields that act as referees.) Before a new theory can be officially proposed to the scientific community,it must be well-written, documented and submitted to an appropriate scientificjournal for publication. If the editors of these prestigious publicationsaccept a research article for publication, they are signaling that theproposed theory has enough merit to be seriously debated and scrutinizedclosely by experts in that particular field of science. Skepticsor proponents of alternative or opposing theories may then try to submittheir research and data, while the original proponents of the proposedtheory may publish new data that answers the skeptics. It may takemany years of often acrimonious debate to settle an issue, resulting inthe adoption, modification, or rejection of a new theory. For example,the Alvarez Meteorite Impact theory (a 6-mile wide meteorite struck theearth 65 million years ago, ending the Cretaceous Period and causing extinctionof the dinosaurs), was first proposed in 1979, and took about 10 yearsof debate before winning over the majority of earth scientists.
These examples contain the words, if and then. Formalized hypotheses contain two variables. One is "independent" and the other is "dependent." The independent variable is the one you, the scientist control and the dependent variable is the one that you observe and/or measure the results.
