to go to Science Fair Project Ideas.
This is where you collect the information or
data. Your data should be in numbers, not just what you see. For example,
say that some of your plants grew 1 centimeter the third day. Don't
say that the plants "look bigger today than they did yesterday."
Words like "bigger" mean different things to different people,
so reporting your results using only words can lead to confusion. You
want to tell people exactly how much your plants grew.
Keep all your results in one notebook.
