Question

write it! explain why scientific knowledge is subject to change. give an example of a time when scientific knowledge changed and what contributed to this change.

Explanation:

Scientific knowledge changes due to new evidence, technological advancements, and paradigm shifts. For example, the understanding of the solar system changed from the geocentric (Earth - centered) model to the heliocentric (Sun - centered) model. Initially, based on observations with the naked eye and philosophical beliefs, people thought Earth was at the center. The invention of the telescope (a technological advancement) allowed Galileo to observe moons orbiting Jupiter and phases of Venus, providing evidence that supported the heliocentric model proposed by Copernicus. This new evidence, along with the work of other astronomers, led to the shift in scientific knowledge about the solar system's structure.

Answer:

Scientific knowledge is subject to change because new evidence from research, technological advancements, and shifts in scientific paradigms can challenge existing theories. An example is the shift from the geocentric to the heliocentric model of the solar system. Initially, the geocentric model (Earth as the center) was accepted, based on naked - eye observations and philosophical ideas. The invention of the telescope allowed Galileo to observe Jupiter's moons and Venus's phases, providing evidence for the heliocentric model (Sun as the center) proposed by Copernicus. This new observational evidence, combined with the work of other astronomers, led to the change in scientific knowledge about the solar system's structure.
