Presenting The ResultsAs you experiment, your job is to observe and to record what happens. You should maintain a bound notebook, not loose-leaf or spiral. In ink, it should include a daily log of exactly what you did and what results you observed. Opinion-type results lend weak support to your hypothesis while measurements lead to stronger support or rejection of your hypothesis.
For example, to say that a plant grew well is opinion; in contrast, saying that the plant grew 7 centimeters is useful in a comparison with other plants. These data or results may answer the questions: How much?, How many?, How high?, How long?, etc. Numerical data may be tabulated or graphed. Use your level of math skills to maximum advantage.
To increase your pool of data, your experiment should be run a number of times. The more times you run your experiment, the more conclusive your data will become.
