Demonstrate in a brief paragraph how the search to explain planetary orbits exemplifies the scientific method and the use of models

Kepler was the one who during the renaissance, came up with the theory of elliptical planetary orbits around the sun. up to that time the planetary orbits were assumed to be circular. by using the observations and data of tycho brahe, and also using both mathematical and physical (relative to the properties of matter) proofs, he thus used the scientific method to determine the type of orbits. in other words, he used the model that brahe had worked out and then developed that model into an accurate appraisal of the orbits. this is the scientific method, starting with what is known and doing investigation into what is unknown by studying the material world and basing one's expanded thinking on the new facts unearthed in the process. in the modern world we all use this method, from figuring out why a vacuum cleaner is not functioning to the theory of plate tectonics.
