What is a scientific theory in simple terms?
noun. a coherent group of propositions formulated to explain a group of facts or phenomena in the natural world and repeatedly confirmed through experiment or observation: the scientific theory of evolution.
What are the 3 characteristics of a scientific theory?
A scientific theory should be:
- Testable: Theories can be supported through a series of scientific research projects or experiments. …
- Replicable: In other words, theories must also be able to be repeated by others. …
- Stable: Another characteristic of theories is that they must be stable. …
- Simple: A theory should be simple.

Can a scientific law be disproven?
A basic principle in science is that any law, theory, or otherwise can be disproven if new facts or evidence are presented. If it cannot be somehow disproven by an experiment, then it is not scientific. Take, for example, the Universal Law of Gravitation.
What happens when a scientific theory is shown?
When a scientific theory is shown to be an accurate description of a phenomenon it’s tested by other scientists to replicate the experiment and confirm the findings. This answer has been confirmed as correct and helpful.
What is an example of scientific theory?
A scientific theory is a broad explanation that is widely accepted because it is supported by a great deal of evidence. Examples of theories in physical science include Dalton’s atomic theory, Einstein’s theory of gravity, and the kinetic theory of matter.
What are examples of scientific laws?
Other examples of laws in physical science include:
- Newton’s first law of motion.
- Newton’s second law of motion.
- Newton’s law of universal gravitation.
- Law of conservation of mass.
- Law of conservation of energy.
- Law of conservation of momentum.
What are the 7 characteristics of scientific knowledge?

Is gravity just a theory?
Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915), which describes gravity not as a force, but as a consequence of the curvature of spacetime caused by the uneven distribution of mass.
What are the advantages of scientific method?
In conclusion the major advantage of the scientific method is that the data it collects is empirical. The information is gained through direct observations and experiments. This is an advantage as it allows psychologists to make claims about the truth of the theory.
Can a scientific theory be proven?
A scientific theory is not the end result of the scientific method; theories can be proven or rejected, just like hypotheses. Theories can be improved or modified as more information is gathered so that the accuracy of the prediction becomes greater over time.
How does scientific theory become law?
When the scientists investigate the hypothesis, they follow a line of reasoning and eventually formulate a theory. Once a theory has been tested thoroughly and is accepted, it becomes a scientific law.
Is evolution a theory or a law?
Evolution is only a theory. It is not a fact or a scientific law.
Is evolution a theory or a fact?
Evolution, in this context, is both a fact and a theory. It is an incontrovertible fact that organisms have changed, or evolved, during the history of life on Earth. And biologists have identified and investigated mechanisms that can explain the major patterns of change.”
What is the difference between a hypothesis and a theory?
In scientific reasoning, a hypothesis is an assumption made before any research has been completed for the sake of testing. … A theory on the other hand is a principle set to explain phenomena already supported by data.
