Identify the core question

The question asks why scientific models must sometimes be changed or revised over time.

Connect to scientific processes

Using the Scientific Method, scientists gather new data and make observations. When new evidence is discovered that contradicts an existing model, the model must be updated or replaced to remain accurate.

Relate to historical examples

Using Solar System Models as a historical reference, the geocentric model was replaced by the heliocentric model because new telescopic observations by Galileo and mathematical calculations by Kepler could not be explained by the old model.

Explain the role of technology

As technology advances, scientific instruments become more precise, allowing scientists to gather higher-quality data that reveals limitations in older, simpler models.

Summarize the nature of science

Using the Scientific Theory framework, scientific knowledge is durable but tentative; models are modified to better explain all available empirical evidence.
</reasoning>

<answer>
Scientific models must be changed when new empirical evidence, observations, or data are discovered that the existing model cannot explain. As technology and scientific instruments improve, scientists can make more precise measurements, leading to new discoveries that require older models to be updated, refined, or replaced to accurately reflect how nature works.
