Problem: What is the effect of the amount of fish feed on the mass of goldfish?

Hypothesis: I think that feeding the goldfish four times a day will greatest increase in the mass of the goldfish.

Explanation:

It is further tested through an experiment or survey and if after many trials it gives same results and the obtained results is concordant with the hypothesis, the hypothesis will then become accepted and a theory or law is formed thereafter.
