Question

Ashfaq is asked to explain the difference between a hypothesis, theory, and scientific law, which are terms used when discussing experiments, research, and scientific methodology. He knows that each term has a distinct meaning, and the terms are not interchangeable. Match the descriptive phrases to the correct term. may still be useful even when evidence does not support it added to Scientific Law Theory do not become lawswell-tested explanation for a range of phenomenaideally should be tested by an experiment in which only one variable is changed Hypothesis highly reliable scientific explanation of events in the natural world that unifies many repeated observationsconcise, specific descriptions of how some aspects of the natural world are expected to behave in a certain situation Scientific Law tentative scientific explanation that can be tested by further observation or by experimentationmay still be useful even when evidence does not support it

Answer 1

Answer:

Hypothesis  

- ideally should be tested by an experiment in which only one variable is changed  

- may still be useful even when evidence does not support it  

- tentative scientific explanation that can be tested by further observation or by experiment

Scientific Law

- concise, specific descriptions of how some aspects of the natural world are expected to behave in a certain situation

- well-tested explanation for a range of phenomena

Theory

- highly reliable scientific explanation of events in the natural world that unifies many repeated observations

Explanation:

A hypothesis is an assumption that intends to explain a phenomenon, while a scientific hypothesis is tested by using the scientific method. The development of a testable hypothesis is the first step during the scientific method. Moreover, a scientific theory is a more coherent and stronger explanation of the natural world, which has been confirmed by experimental and/or observational procedures. Finally, a scientific law is a solid statement funded on repeated observational/experimental methods. A scientific law can be used not only for understanding but also for predicting different phenomena from the real world.
