3. Six Criteria of Science Consistent, Observable, Natural, Predictable, Testable, Tentative.

4. Consistency : The results of observations and/or experiments are reasonably the same when repeated.
Green plants will grow towards a light source.
Walking under a ladder will cause bad luck.

5. Observability : The event or evidence of the event, can be observed and explained. The observations are limited to the basic human senses or to extensions of the senses.
Some plants eat meat.
Extraterrestrial beings have visited Earth.

6. Natural : A natural cause (mechanism) must be used to explain why or how the event happens.
1. Green plants convert sunlight into energy.
2. With a rod, Moses parted the sea so his people could cross to the other side..

7. Predictability : Specific predictions can be used to foretell an event
Predictability : Specific predictions can be used to foretell an event. Each prediction can be tested to determine if the prediction is true or false.
Without sunlight (or artificial light), green plants will die.
If you are a "Scorpio", your horoscope for today is "You'll be saying 'I feel rich !' Lunar position highlights back pay, refunds, correction of accounting error."

8. Testability : the event must be testable through the processes of science, and controlled experimentation.
The Bermuda Triangle causes ships and planes to sink and disappear.
Life comes from life and cannot come from non-life.

9. Tentativeness : Scientific theories are changeable and correctable, even to the point of the theory being proven wrong. Scientific theories have been modified and will continue to be modified
Pluto was once a planet but due to it’s orbits, is now considered a dwarf planet.
We know that the world began about 6000 years ago, and nothing will change that.
