How to Write a Hypothesis The solution of a scientific problem never begins directly with experiment. This procedure is preceded by a very important stage associated with the hypothesis. The scientific hypothesis is a statement containing an assumption about the solution of the problem faced by the researcher. Theoretical background In formulating the hypothesis, you build an assumption about how you intend to achieve the stated goal of the study.
Test Your Hypothesis by Doing an Experiment Analyze Your Data and Draw a Conclusion Communicate Your Results Following the scientific methodwe 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 what we "think" will happen.
We make an "educated guess. We set out to prove or disprove the 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.
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 to do. If I never water my plant, it will dry out and die. That seems like an obvious statement, right? The above hypothesis is 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.
Hypotheses Tips 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.
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 be.
For more information about identifying variables, see: Variables in Your Science Fair Project. Make sure your hypothesis is "testable.
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. Identified the variables in the project.
Included the independent and dependent variables in the hypothesis statement.
This helps ensure that your statement is specific enough. You may find many studies similar to yours have already been conducted. What you learn from available research and data can help you shape your project and hypothesis.
Answering some scientific questions can involve more than one experiment, each with its own hypothesis. Make sure your hypothesis is a specific statement relating to a single experiment. Putting it in Action To help demonstrate the above principles and techniques for developing and writing solid, specific, and testable hypotheses, Sandra and Kristin, two of our staff scientists, offer the following good and bad examples.Writing the Discussion.
The discussion section is a framing section, like the Introduction, which returns to the significance argument set up in your introduction. What Are Examples of a Hypothesis? Search the site GO. Science. Chemistry Scientific Method Basics Chemical Laws The null hypothesis sometimes is called the "no difference" hypothesis.
The null hypothesis is good for experimentation because it's simple to disprove. How to Write a Testable Hypothesis.

Aims to Write a Good Hypothesis. In any form of experimentation or research, the fundamental aim to write a hypothesis is to explain the right track and emphasis of the study. It not only involves the purpose of the study but also highlights the variables to carry out undergo research.
All good ideas presented so far. I know that bullying is allowed in some homes, as well. It's called "kidding around" and it's seen as a way of making kids tougher and more able to handle things.
