EVERYDAY SCIENCE

Detailed explanation-1: -Hypotheses must be testable, and once tested, they can be supported by evidence. If a statement is made that cannot be tested and disproved, then it is not a hypothesis. Sometimes it is possible to restate an opinion so that it can become a hypothesis.

Detailed explanation-2: -Answer and Explanation: A theory is supported by scientific evidence and verified research. A theory predicts certain results, which are verified by experiments or observations. If experiments or observations do not verify the predictions made by a theory, then the theory is not said to be valid.

Detailed explanation-3: -Correction: Hypotheses cannot become theories and theories cannot become laws. Hypotheses, theories, and laws are all scientific explanations but they differ in breadth, not in level of support. Theories apply to a broader range of phenomena than do hypotheses.

Detailed explanation-4: -The word hypothesis can be defined as an “educated guess” A scientific hypothesis must meet two criteria: It must be testable and it must be falsifiable. If a hypothesis cannot be tested by making observations, it is not scientific.

Detailed explanation-5: -Hypotheses are used to support scientific research and create breakthroughs in knowledge. These brief statements are what form the basis of entire research experiments. Thus, a flaw in the formulation of a hypothesis may cause a flaw in the design of an entire experiment.
