I think putting the soda in a tube off ice water will make it get cold the fastest. Chocolate may cause pimples All of these are examples of hypotheses because they use the tentative word "may.

However, the internet is a constantly changing place and these links may not work or the external web site may have changed. For more information about identifying variables, see: You haven't actually done the experiment.

I believe that the Heafty brand will hold 30 pounds of rocks for the longest amout of time. What is your problem statement.

My problem statement is how far the animals run. The hypothesis is very much like the problem statement except it is the answer to your question. Most people would agree with the hypothesis that: The question should always start with either which or how.

In this case, take the purpose from your hypothesis. I think the fruit juice with the most surgar will ferment the most. Which is why scientists only support or not their hypothesis with data, rather than proving them. Using this new information, let's try that hypothesis again.

Staff Scientist Dave reminds that scientific experiments become a dialogue between and among scientists and that hypotheses are rarely if ever "eternal.

Step 5: Hypothesis Statement

Most are based on an experiment or test that was conducted. We make an "educated guess. Make sure your hypothesis is a specific statement relating to a single experiment.

I think the smaller car will travel the farthest. Examples of Hypotheses and Predictions Question Prediction How does the size of a dog affect how much food it eats. The question, "Do fish see in color. We make an "educated guess.

How many volts of electicity can make my motor go faster. My hypothesis is that new tennisballs bounce highest. Reading your hypothesis should tell a teacher or judge exactly what you thought was going to happen when you started your project.


I think that the tap water will make the plant grow tallest. Which brabd of trash bags will hold 30 pounds of rocks for the longest amount of time.

What is a hypothesis?

As you can see, both of these problem statements fit the format described above. The hypothesis is the question that you plan to answer or what you plan to prove.

When we use this term we are actually referring to a hypothesis. 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.

In a science fair setting, judges can be just as impressed by projects that start out with a faulty hypothesis; what matters more is whether you understood your science fair project, had a well-controlled experiment, and have ideas about what you would do next to improve your project if you had more time.

How to Write a Hypothesis

A hypothesis is a description of a pattern in nature or an explanation about some real-world phenomenon that can be tested through observation and experimentation.

At this point, some scientists write a research hypothesis, a statement that includes the hypothesis, the experiment, "It helped me 79%(55). For the investigative science project, it is important to have a hypothesis that can be proved or disproved, and one that can be measured. One way of ensuring that your hypothesis is measurable is to see if you can identify the following variables for your science project.

In the world of statistics and science, most hypotheses are written as "if then" statements.

How to Write a Thesis Statement for a Science Report

For example someone performing experiments on plant growth might report this hypothesis: "If I give a plant an unlimited amount of sunlight, then the plant will grow to its largest possible size.". 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 You can see from the basic outline of the Scientific Method below that writing your hypothesis comes early in the process. The Three-Step Process. It can quite difficult to isolate a testable hypothesis after all of the research and study.

The best way is to adopt a three-step hypothesis; this will help you to narrow things down, and is the most foolproof guide to how to write a hypothesis.
