A real life example of a scientific investigation is CSI. Specialists examine crime scenes using science to determine what happened.
================================

Looking for your house keys:

hypothesis 1.: "my keys are in my jacket pocket."
test 1. - look in jacket pocket, keys not there.
hypothesis 2.: "they are on top of my dresser."
test 2.- look on dresser, keys not there
hypothesis 3. - "I left them in the front door last night"
test 3. - look in door, keys are there.

The scientific method just means proposing an hypothesis, testing it, and (re-)proposing a (new?) hypothesis based on the data, and testing that one ... and repeating.
