Hi, Seeker; good to have you with us!
At the outset, I would point out that the thread title, "Science vs. Religion," is most regrettable because in the Baha'i view, the two are
NOT in contradiction, but rather dovetail very nicely!
Art already mentioned superstition and materialism as the result of using one without the other. The examples I generally give for these are "witch-burning" and "bigger and better nukes."
Science may be said to explain the "how" of things, whereas religion explains "Who" and "why." They thus address different, largely non-overlapping domains, but come together nicely to form a complete whole!
And as Art indicated, the quickest way to get ilnto trouble is to use either one without the other!
The Baha'i scriptures also say (sorry: I don't have the citation handy) that if a religious doctrine disagrees with
established science, then that doctrine is simply wrong.
There is also this marvelous quote from 'Abdu'l-Baha in
Some Answered Questions:
[E]ven in Europe it is admitted that religion is the opponent of science, and that science is the destroyer of the foundations of religion. While the religion of God is the promoter of truth, the founder of science and knowledge, it is full of goodwill for learned men; it is the civilizer of mankind, the discoverer of the secrets of nature, and the enlightener of the horizons of the world. Consequently, how can it be said to oppose knowledge? God forbid! Nay, for God, knowledge is the most glorious gift of man and the most noble of human perfections. To oppose knowledge is ignorant, and he who detests knowledge and science is not a man, but rather an animal without intelligence. For knowledge is light, life, felicity, perfection, beauty and the means of approaching the Threshold of Unity. It is the honor and glory of the world of humanity, and the greatest bounty of God. Knowledge is identical with guidance, and ignorance is real error.
Happy are those who spend their days in gaining knowledge, in discovering the secrets of nature, and in penetrating the subtleties of pure truth! Woe to those who are contented with ignorance, whose hearts are gladdened by thoughtless imitation, who have fallen into the lowest depths of ignorance and foolishness, and who have wasted their lives!

I hope this helps.
