Question

1. A scientific hypothesis can become a theory if ______.
A) the entire community accepts it
B) the hypothesis is tested extensively and competing hypothesis are eliminated
C) there are no other competing hypothesis
D) the hypothesis can be tested at least once
2) A preliminary untested explanation that tries to explain how or why things happen in the manner observed is a scientific ________.
A) law
B) theory
C) fact
D) hypothesis

Answer 1

1) - it can become a theory if the hypothesis is tested extensively and competing hypotheses are eliminated - other options are not enough


2) This is a hypothesis. A theory is basically almost an established truth, which can still be changed with new data, but which as far as we know is true.

Answer 2

1) The answer is: B) the hypothesis is tested extensively and competing hypothesis are eliminated.

Theory is a tested, unifying explanation for a set of verified facts.  

Theory is a system of explanations that ties together a lot of facts.

Steps of the scientific method:  

1) ask a question about something that is observed.  

2) do background research.  

3) construct a hypothesis, an attempt to answer questions with an explanation that can be tested.  

4) test of hypothesis.  

5) analyze collected data and draw a conclusion.  

2) The answer is: D) hypothesis.

Hypothesis is a suggested explanation for an observable phenomenon.

Experimenters may test and reject several hypotheses before solving the problem.

A working hypothesis is provisionally accepted as a basis for further research.

A law in science is a generalized rule to explain a body of observations in the form of a verbal or mathematical statement.
