The hypothesis is an educated, testable prediction about what will happen. A good hypothesis is written in clear and simple language. Reading your hypothesis should tell a teacher or judge exactly what you thought was going to happen when you started your project. Keep the variables in mind. A good hypothesis defines the variables in easy-to-measure terms, like who the participants are, what changes during the testing, and what the effect of the changes will. (For more information about identifying variables, dream see: Variables in your Science fair Project.) make sure your hypothesis is "testable." to prove or disprove your hypothesis, you need to be able to do an experiment and take measurements or make observations to see how two things. You should also be able to repeat your experiment over and over again, if necessary. To create a "testable" hypothesis make sure you have done all of these things: Thought about what experiments you will need to carry out to do the test.
The above hypothesis is essay too simplistic for most middle- to upper-grade science projects, however. 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. Similarly, the hypothesis should be written before you begin your experimental procedures—not after the fact. Our staff scientists offer the following tips for thinking about and writing good hypotheses. The question comes first. Before you make a hypothesis, you have to clearly identify the question you are interested in studying. A hypothesis is a statement, not a question. Your hypothesis is not the scientific question in your project.
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. In other words, you don't simply "guess." you're not taking a shot in the dark. You're not pulling your statement out of thin air. Instead, you make an "educated guess" based on what you already know and what you have already learned from your research. If you keep in mind the format of a well-constructed hypothesis, you should find that writing your hypothesis is not difficult. You'll also find that in order to write a solid hypothesis, you need to understand what your variables are for your project. If I never water my plant, it will dry out and die. That seems like an obvious statement, right?
The Scientific Method - science made simple
A hypothesis is tested by drawing conclusions from it; if observation and experimentation show a conclusion to be false, the hypothesis must be false. (see scientific method and theory.)

By science buddies on February 23, 2010 9:23 am "If _I do this then _this_ will happen.". 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. Step by Step, operations you can see from the basic outline of the.
Scientific Method below that writing your hypothesis comes early in the process: Ask a question, do background Research, construct. Hypothesis, test your, hypothesis by doing an Experiment, analyze your Data and Draw a conclusion. Communicate your Results, following the scientific method, we come up with a question that we want to answer, we do some initial research, and then before we set out to answer the question by performing an experiment and observing what happens, we first clearly identify. We make an "educated guess. we write a hypothesis. We set out to prove or disprove the hypothesis.
New hypotheses inconsistent with well-established laws are generally rejected, barring major changes to the approach. An example is the law of conservation of energy, which was firmly established but had to be qualified with the revolutionary advent of quantum mechanics and the uncertainty principle. A theory is a set of statements, including laws and hypotheses, that explains a group of observations or phenomena in terms of those laws and hypotheses. A theory thus accounts for a wider variety of events than a law does. Broad acceptance of a theory comes when it has been tested repeatedly on new data and been used to make accurate predictions. Although a theory generally contains hypotheses that are still open to revision, sometimes it is hard to know where the hypothesis ends and the law or theory begins.
Albert Einstein's theory of relativity, for example, consists of statements that were originally considered to be hypotheses (and daring at that). But all the hypotheses of relativity have now achieved the authority of scientific laws, and Einstein's theory has supplanted Newton's laws of motion. In some cases, such as the germ theory of infectious disease, a theory becomes so completely accepted, it stops being referred to as a theory. The American Heritage Science dictionary copyright 2011.

Hypotheses (heye-poth-uh-seez) In science, a statement of a possible explanation for some natural phenomenon.
God: The failed Hypothesis
Hypothesis in Science hī-pŏthĭ-sĭs Plural hypotheses (hī-pŏthĭ-sēz) A statement that explains or makes generalizations about a set of facts or principles, usually forming a basis for possible experiments to confirm its viability. Show More Usage: The words hypothesis, law, and theory movie refer to different kinds of statements, or sets of statements, that scientists make about natural phenomena. A hypothesis is a proposition that attempts to explain a set of facts in a unified way. It generally forms the basis of experiments designed to establish its plausibility. Simplicity, elegance, and consistency with previously established hypotheses or laws are also major factors in determining the acceptance of a hypothesis. Though a hypothesis can never be proven true (in fact, hypotheses generally leave some facts unexplained it can sometimes be verified beyond reasonable doubt in the context of a particular theoretical approach. A scientific law is a hypothesis that is assumed to be universally true. A law has good predictive power, allowing a scientist (or engineer) to model a physical system and predict what will happen under various conditions.
