3. '''Use of the hypothesis to predict the existence of other phenomena, or to predict the results of new observations.''' (I test various objects that are more or less dense than water by putting them in a tub; finding my hypothesis holds true I predict that any object that is less dense than water will float)

(To see whether my hypothesis holds true, I predict that any object that is less dense than water will float and any object more dense than water will sink; I test various objects that are more or less dense than water by putting them in a tub.)

4. '''Replication of the experiments and results by independent experimenters.''' (rather than take my word for it, my neighbors try the same experiment and look for any flaws in my methodology)
