Tutorial

 

A hypothesis is a prediction about the answer to a question or an explanation for an observation being made. 

 

A Hypothesis should:

 

Be Logical

Not a logical hypothesis:

If I were to drink a soda I could fly to the moon.

We know that gravity prevents me from flying and that I would be unable to breathe in the vacuum of space.

 

Account for Relevant Information - Check to see if the experiment has already been done.

Perhaps another experiment has already tested your hypothesis.  Can other experiments that have already been done help you alter your hypothesis?

 

Testable - There must be a way to test the hypothesis with an experiment.

Can you test your hypothesis by setting up an experiment?

 

Simple - The simplest form of a question make the best hypotheses.

When writing a hypothesis, choose the simplest way to express it so that it is easy to understand and to test.

 

Example Hypothesis:

If I leave my porch light on at night, more bugs will come to my porch.
