Question

For a scientific theory to be valid, this is what you need to do.

A. perform experiments.
B. obtain new results each time.
C. find a new, more complex explanation.
D. make predictions."

Answer 1

To validate a scientific theory, a hypothesis must be proposed, experiments must be conducted, and the hypothesis must be refined based on the results. The validity of the hypothesis is determined by obtaining measurable evidence through experiments.

Step-by-step explanation:

In order for a scientific theory to be valid, several steps need to be followed:

1. Propose a hypothesis or a testable explanation for the observed phenomenon.
2. Design and perform experiments to test the hypothesis.
3. Refine the hypothesis based on the results of the experiments.
4. Make predictions based on the hypothesis.

The validity of a hypothesis is determined by conducting experiments and obtaining measurable evidence that either supports or contradicts the hypothesis.

The more experiments that agree with the hypothesis, the more likely it is to be accepted as a useful description of nature.
