How to write a high school science fair hypothesis

Sometimes people refer to the tentative answer as "an educated guess. If I brush my teeth every day, then I will not develop cavities.

If I increase the current supplied to an electric motor, then the RPMs revolutions per minute of the motor will increase. If they leave the classroom, the students feel free to break the rules and talk more, making the room nosier. I categorized my subjects by age group as kid, teenager, young adult, adult and senior.

But wait a minute. Does an electric motor turn faster if you increase the current. The first game has a mouse cursor that moves normally. You then predict that you will find earthworms in the dirt in Florida, which has warm winters, but not Alaska, which has cold winters.

This goes back to the point that nature is complex—so complex that it takes more than a single experiment to figure it all out because a single experiment could give you misleading data.

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. If I eat more vegetables, then I will lose weight faster. Teachers have rules about when to talk in the classroom. Now, using all your research, try to restate that hypothesis.

To get the energy their bodies need, the larger animals eat more food. You can read more about a science fair judge's view on disproving your hypothesis here. An ice cube made with tap water will melt in less than 30 minutes in a room at sea level with a temperature of 20C or 68F.

You will use the engineering design process to create your fair entry. If I measure the noise level in a classroom when a teacher is in it and when she leaves the room, then I will see that the noise level is higher when my teacher is not in my classroom. The second experiment does not require any more data collection, but it does require looking at the data from experiment 1 in a different way.

Most importantly, through my project, phonemes were established as a basis for the short-term memorization of words. The part that remains constant and is used as a comparison to the test groups.

If I increase the current supplied to an electric motor, then the RPMs revolutions per minute of the motor will increase.

Go Back to Research Task 3: A single hypothesis can lead to multiple predictions, but generally, one or two predictions is enough to tackle for a science fair project.

Prepare your abstracts and compliance checklist You will need to bring to Check-In day: The subject plays this game 3 times. What if the ice cube was made from salt water, or you sprinkled salt on a regular ice cube. So, was your hypothesis right. No, it sounds like you are stating the obvious.

In both games, a target circle is presentedat a random location on the computer screen. As more current flows through the motor's electromagnet, the strength of the magnetic field increases, thus turning the motor faster. When the target is clicked on, a new target appears at another random location on the screen.

Lastly, in all non-phoneme trials i. Up and down are also reversed. For example, let us say that you hypothesize that earthworms do not exist in places that have very cold winters because it is too cold for them to survive.

This goes back to the point that nature is complex—so complex that it takes more than a single experiment to figure it all out because a single experiment could give you misleading data.

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 experiment. Fertilizer adds those nutrients to the soil, thus allowing plants to grow more.

If I increase the current supplied to an electric motor, then the RPMs revolutions per minute of the motor will increase. What happens if, at the end of your science project, you look at the data you have collected and you realize it does not support your hypothesis.

Don't forget that elevation above sea level changes air pressure too. A hypothesis has classical been referred to as an educated guess. In the context of the scientific method, this description is somewhat correct.

After a problem is identified, the scientist would typically conduct some research about the problem and then make a hypothesis about what will happen.

Writing a Hypothesis - Remember, a hypothesis is an educated guess. Based on the research you did, your prior knowledge, and your past experiences, you need to write a testable hypothesis - what you think will happen when you test it.

Writing a science fair project report may seem like a challenging task, but it is not as difficult as it first appears.

This is a format that you may use to write a science project report. This is a format that you may use to write a science project report. A better explanation of the purpose of a hypothesis is that a hypothesis is a proposed solution to a problem.

Hypotheses have not yet been supported by any measurable data. In fact, we often confuse this term with the word theory in our everyday language.

Now that you know your independent and dependent variable, the rest of the science fair project is a piece of cake. Your problem statement and hypothesis are extremely easy to write if you have determined your independent and dependent variables.
