A hypothesis is, as defined by freedictionary.com, a
"tentative explanation for an observation, phenomenon, or scientific
problem that can be tested by further investigation". When performing a
lab, the first step is always to propose a hypothesis. Your hypothesis should
be a statement about the end result of the experiment.

The steps to creating a hypothesis are as follows:

1.) "Ask a Question"- This question should be relevant to what you believe your experiment will reveal, should be able to be answered through the experiment and be a foundation to build your actual hypothesis off of. You should try to answer one of the following prompts: Who? what? when? why? or how? For example, "What causes the reaction of soda when you add Mentos to it?"

2.) "Gather Background Information"- You should know what your experiment is trying to prove, the steps you must take to prove this information, and why your hypothesis should be correct. For instance, the above mentioned hypothesis has all of these. The "If___, then____ because____" statement states what you're trying to prove. "If I add four Mentos to a liter of Pepsi," is the step you are going to take to prove it. The statement following the "because" is why your hypothesis should be correct.

3.) "Form a Hypothesis"- Your hypothesis should follow the "If (independent variable), then (dependent variable) because (reasoning)" form. For example, if someone does an experiment about whether or not soda reacts to Mentos, then their hypothesis should be, "If I add four Mentos to a liter of Pepsi, then the Mentos will cause the Pepsi to spill over because of the carbonation of the soda and the way the candy dissolves."
