Science is the method men use to discover the elements, nature, substance and age of his universe among other things, the opposite of faith which merely rubber stamps myth into reality. The real difference between science and religion is that those who fail to adhere to the tenants of religion are faced with either damnation or force of law, where science can always be challenged with facts.
So, getting back to the original question. . . based upon your defintion, would you say that science requires the ability to observe and/or to repeat in a lab, or does science include presumption and jumping to conclusions that cannot be verified OR falsified?
