Scientific method

The scientific method is as follows, in summary, in sequence of the process.

1. Observation
2. Hypothesis
3. Prediction
4. Test

Example:

1. The sun seems to rise a lot in the mornings.
2. I hypothesize that the sun rises every morning.
3. I predict it will rise tomorrow morning.
4. Your prediction is proven the next morning when you test to see if the sun actually comes up.

Also these results have to be reproducible by other scientists, which is why ghosts have not been proven to exist yet.
