A student has been studying electrical circuits in class. The student suggests that replacing a wire with rubber tubing will stop the current from flowing through a circuit. Which term best describes this idea?

hypothesis

conclusion

theory

law

hypothesis

Explanation:

This is a hypothesis.

A hypothesis is a simple scientific guess into nature usually drawn from succinct and detailed inquiry into the nature.

It is usually preceded by observation making and asking of questions.

Now, we formulate a testable and falsifiable hypothesis which experiments can prove or disprove. This will then lead to the formation of either a theory or law.

The student is predicting from his observation that if the rubber tubing replaces wire, current will not flow.
