scientific fact or scientific law
No. A scientific theory is a proven set of rules describing reality. The "everyday" usage of the word is what a scientist would call a hypothesis, and others would call an unsubstantiated guess.
a hypothesis
variables in an experiment cannot be manipulated by the researcher
A hypothesis cannot be call a theory because,it has not supported a prediction even in the face of several experiment.
An experiment is used by scientists to find answers to questions or solve a problem. Any good experiment starts with a hypothesis. The experiment is then used to prove whether it is true or false.

A theory. If it has been proven and is replicatable, it is a fact.
A False Positive.
It begins as a hypothesis, only after it has been thoroughly tested over time can it be called a theory. (Note that what non-scientists call a theory is actually just a hypothesis.)
A theory that has been confirmed through rigorous testing and observation is typically referred to as a scientific law.
The hypothesis test.

Ye, definitely, but that would be a hypothesis or educated guess. Another way to call that prediction is inference, since there's a reasonable basis.
A hypothesis is any idea used to explain and test a scientific idea, while a theory is a hypothesis that has become scientifically accepted. For example, say I hypothesize that rocks in a stream are worn smooth by erosion. This is a hypothesis of sorts. I test this hypothesis by putting rocks in a room and in a stream, and conclude that the stream rocks have been worn smooth. If I complete multiple tests and the scientific community believes in my conclusion, I would call it the Theory of Water Erosion, or something similar.
They can't be proven with 100% scientific certainty. No one was there to witness the big bang, so we can't technically say that it definitely happened. And we wouldn't call the Steady State Theory a law, since it has been seriously discounted in recent decades. It is worth adding that when time honored theories become 'laws' it is not because they have be proven with 100% certainty. It is because they have survived the test of time and the test of many, many scientific challenges. Nothing can really be proven with 100% scientific certainty.
