Research questions allow the researcher to conduct more open-ended queries, and a wide range of results can be reported.
A properly constructed research question should always be clear and concise.
They are useful in testing a specific theory or model.
A complete hypothesis always includes the variables, population and the predicted relationship between the variables.
This formulaic approach to making a statement about what you "think" will happen is the basis of most science fair projects and much scientific exploration.
We make an "educated guess." We write a hypothesis. What you "think" will happen, of course, should be based on your preliminary research and your understanding of the science and scientific principles involved in your proposed experiment or study.Similarly, the hypothesis should be written you begin your experimental procedures—not after the fact.Keep in mind that writing the hypothesis is an early step in the process of doing a science project.You'll also find that in order to write a solid hypothesis, you need to understand what your variables are for your project. As you work on deciding what question you will explore, you should be looking for something for which the answer is not already obvious or already known (to you).When you write your hypothesis, it should be based on your "educated guess" not on known data.This statement is speculation, not a hypothesis." Sandra says: "This statement is not 'bite size.' Whether or not something is a 'good natural pesticide' is too vague for a science fair project.There is no clear indication of what will be measured to evaluate the prediction." Throughout history, scientists have posed hypotheses and then set out to prove or disprove them.Sir Isaac Newton (1643-1727) put forth a hypothesis to explain this observation, which might be stated as 'objects with mass attract each other through a gravitational field.'" Newton's hypothesis demonstrates the techniques for writing a good hypothesis: It is testable. It builds upon previously accumulated knowledge (e.g., Newton's work explained the observed orbits of the planets)."As it turns out, despite its incredible explanatory power, Newton's hypothesis was wrong," says Dave.Staff Scientist Dave reminds that scientific experiments become a dialogue between and among scientists and that hypotheses are rarely (if ever) "eternal." In other words, whether that research appears a month or a hundred years later.A look at the work of Sir Isaac Newton and Albert Einstein, more than 100 years apart, shows good hypothesis-writing in action.
