In science class, maria observes a white-colored cut flower. she sees that the petals turn red when the flower is sitting in a vase that has red-colored water. she forms a hypothesis that the color reaches the flower through the stem. what should maria do to confirm the hypothesis?

A hypothesis refers to a suggested illustration for a phenomenon. For a hypothesis to be a scientific hypothesis, there is a need to test it. Upon analysis, a hypothesis can be modified or rejected, but it can never be proved 100 percent accurate.  

A hypothesis needs more work by the individual testing it in order to either disprove or confirm it. A working hypothesis refers to a hypothesis, which is tentatively accepted as a foundation for a further research.
