How does observing patterns in the world help scientists answer scientific questions?

Answer:
Patterns offer clues as to what is going on. The clues lead scientists to make a hypothesis, a tentative explanation that accounts for the observed pattern. The hypothesis then gets tested, sometimes in ingenious ways. If the hypothesis holds up, you may have a working theory on your hands. The theory would be the best current explanation for the pattern. If you can explain the pattern, you have the answer to a scientific question. If the theory is good, it will lead to other possibilities that have not yet been observed. And if the theory is excellent, these unobserved possibilities will eventually be detected. These new observations will be considered strong evidence in support of the theory's soundness.
