Question

what is a model in science? a a rule that describes a pattern in nature b a representation of a phenomenon, a system, a process, or a solution to an engineering problem that helps people visualize or understand the concept c the act of using one or more of your senses to gather information and take note of what occurs d the factor that is changed by the investigator to observe how it affects a dependent variable

Explanation:

To determine the correct answer, we analyze each option:

• Option A: A rule describing a natural pattern is a scientific law, not a model.
• Option B: A model in science is a representation (physical, conceptual, or mathematical) of a phenomenon, system, process, or solution to a problem that aids in understanding. This matches the definition of a scientific model.
• Option C: The act of gathering information via senses is observation, not a model.
• Option D: A factor affecting a dependent variable is an independent variable, not a model.

Answer:

B. A representation of a phenomenon, a system, a process, or a solution to an engineering problem that helps people visualize or understand the concept
