Science Fair: Step One

Where to begin?  Begin with an idea.  Start with Science Buddies, a terrific site with thousands of ideas.  Once the idea is fixed, it is time to write a hypothesis.  There should be two parts: the null hypothesis and the alternative hypothesis.  Here is an example.


Hypothesis

The null hypothesis for this experiment is that the  average nitrate levels in Mill Creek (at the public access point in Bunker Hill) will not contain exceed safe drinking water standards during the thirty day period of water testing.

The alternative hypothesis for this experiment is that the average nitrate levels in Mill Creek (at the public access point in Bunker Hill) will contain nitrate levels that do    exceed safe drinking water standards during the thirty day period of water testing.
