How to write a hypothesis statement if then

And for the curious, yes there are earthworms in Alaska. If I let a pound dog and a pound dog eat as much food as they want, then the pound dog will eat more than the pound dog. The point of a science project is not to prove your hypothesis right.

Below is a short explanation of a hypothesis statement and some examples of hypothesis statements. We make an "educated guess. Your hypothesis is not the scientific question in your project.

Examples of Hypotheses and Predictions Question Prediction How does the size of a dog affect how much food it eats? Teachers have rules about when to talk in the classroom.

How to Write a Hypothesis

If the diffusion rate dependent variable through a membrane is related to molecular size independent variablethen the smaller the molecule the faster it will pass through the membrane. Identified the variables in the project.

A hypothesis is a tentative, testable answer to a scientific question. The above hypothesis is too simplistic for most middle- to upper-grade science projects, however.

When you write your hypothesis, it should be based on your "educated guess" not on known data. Larger animals of the same species expend more energy than smaller animals of the same type. To create a "testable" hypothesis make sure you have done all of these things: It is worth noting, scientists never talk about their hypothesis being "right" or "wrong.

By its very nature, it is not testable. Once a scientist has a scientific question she is interested in, the scientist reads up to find out what is already known on the topic. I think that leaves change colors in the fall because they are not being exposed to as much sunlight.

What if My Hypothesis is Wrong? If I add fertilizer to the soil of some tomato seedlings, but not others, then the seedlings that got fertilizer will grow taller and have more leaves than the non-fertilized ones.

If you keep in mind the format of a well-constructed hypothesis, you should find that writing your hypothesis is not difficult to do. So, was your hypothesis right?

A Strong Hypothesis

A hypothesis leads to one or more predictions that can be tested by experimenting. If these statements had not been written carefully, they may not have been a hypotheses at all. Is a classroom noisier when the teacher leaves the room? If they leave the classroom, the students feel free to break the rules and talk more, making the room nosier.

The question comes first. For any other use, please contact Science Buddies. If your science fair is over, leave a comment here to let us know what your hypothesis was for your project. Make sure your hypothesis is a specific statement relating to a single experiment.

Educators can also assign students an online submission form to fill out detailing the hypothesis of their science project. If the rate of photosynthesis is related to wave lengths of light, then exposing a plant to different colors of light will produce different amounts of oxygen.Sep 09,  · Then, determine the variables in your question and write a simple statement about how they might be related.

Try to focus on specific predictions and variables, such as age or segment of the population, to make your hypothesis easier to 80%(73). If the alternative is rejected, then you need to go back and refine the initial hypothesis or design a completely new research program.

This is part of the scientific process, striving for greater accuracy and developing ever more refined hypotheses. What Are Examples of a Hypothesis? Search the site GO. Science. Chemistry Scientific Method Basics Chemical Laws most hypothesis are either "If, then" statements or else forms of the null hypothesis.

The null hypothesis sometimes is called the "no difference" hypothesis. How to Write a Testable Hypothesis.

Hypothesis

What's a Hypothesis? What Is a. A Strong Hypothesis We write a hypothesis. 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.

Make sure your hypothesis is a specific statement. In a hypothesis statement, students make a prediction about what they think will happen or is happening in their experiment. A better way to write a hypotheses is to use a formalized hypotheses.

Example: If skin cancer is related to ultraviolet light, then people with a high exposure to uv light will have a higher frequency of skin cancer.

A hypothesis leads to one or more predictions that can be tested by experimenting.

Step 5: Hypothesis Statement

Predictions often take the shape of "If ____then ____" statements, but do not have to. Predictions should include both an independent variable (the factor you change in an experiment) and a dependent variable (the factor you observe or measure in an .
