Well what you can look at for example is the level of certain chemicals in several different locations. For example:
Water from different lakes, rivers
Drinking water with tap water
..etc...
Just do an experiment about how water effects plants
experiment means
actually wanting to do a science fair experiment?
easy
volcano
The experiment is what you test and how you test it. Your entire project is based on the experiment.
volcano experiment
In the Science Fair, 'constants' are things that remain the same in your experiment. For example, you might want to keep the temperature constant for the duration of the experiment.
An appendix defines vocabulary words described in your science fair project, photos of the progress of your experiment, and additional information about your science fair topic.
To answer this question, you would have to have a scientific experiment's results. If you are participating in a science fair you could use this as your science fair project, therefore answering your scientific inquiry and getting a science fair project idea at the same time!!
it really depends on what your experiment is...
