What term describes the process of testing new ideas to discover something new?

The process of testing new ideas to discover something new is accurately described by the term "experiment." In a scientific or research context, an experiment involves systematically manipulating variables and observing the results to understand a phenomenon better. This hands-on approach allows researchers to test hypotheses, gather data, and draw conclusions based on what they observe.

Exploration typically refers to a broader search or investigation into unfamiliar areas, which may not involve direct testing or manipulation of variables. Discussion focuses on sharing thoughts and engaging in dialogue rather than conducting tests. Evaluation usually involves assessing existing ideas or data, determining their value or effectiveness, rather than generating new knowledge through testing. Thus, "experiment" is the most precise term to describe the process of testing ideas in order to uncover new information.
