and WritingCopernicus’ revolutionary workMain idea of each part: Para 1 Brief introductionPara 2 The cause ofCopernicus’ theoryParas 34 The process ofCopernicus’theoryPara 5 The significance ofCopernicus’ theoryBefore Copernicus’ theoryCopernicus’ theory made the earth. earth was the center of the solar system. sun is the center of the solar system and the planets go around it except the moon. earth is spinning as it goes round the sun.Research and ActivitiesThe theme of the activity is“a great scientist in our eyes”.Get the students to work in groups and introduce a great scientist in their , they need to decide which scientist they think is the , collect as much information as possible about the scientist, such as his/her life, achievements, and so the end, each group presents it to the whole activity is designed to arouse the students’ interest in science, cultivate their team spirit and learn something from these great also helps them learn to search for information and organize it well.Reference for TeachingNicolaus CopernicusBorn on , 1473, in Thorn (Torun), Poland, Nicolaus Copernicus was destined to bee, through the publication of his heliocentric theory 70 years later, one of the seminal figures in the history of scientific son of a prosperous merchant, he was raised after his father’s death by a maternal uncle, who enabled him to enter the University of Krakow, then famous for its mathematics, philosophy, and astronomy experience stimulated the young Copernicus to study further liberal arts at Bologna (14961501), medicine at Padua, and law at the University of Ferrara, from which he emerged in 1503 with the doctorate in canon afterward he returned to Poland and eventually settled permanently at the cathedral in Frauenberg (Frombork), less than 100 miles from his his uncle’s influence he had been elected a canon of the church even before his journey to not only faithfully performed his ecclesiastical duties, but also practiced medicine, wrote a treatise on monetary reform, and turned his attention to a subject in which he had long been interestedastronomy.By May 1514 Copernicus had written De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres, 1543).This classic work challenged the geocentric cosmology that had been accepted since the time of proposed that the earth goes round the sun with the other planets.The new theory that Copernicus espoused in De revolutionibus exhibits a peculiar mixture of both radical and conservative the midst of his radical reordering of the structure of the universe, Copernicus still adhered to the ancient Aristotelian doctrines of solid celestial spheres and perfect circular motion of heavenly bodies, and he held essentially intact the entire Aristotelian physics of , with significant innovations, he clung to the Ptolemaic representation of planetary motion by means of plicated binations of circles called Copernicus realized that his theory implied an enormous increase in the size of the universe, he declined to pronounce it infinite.These aspects of the Copernican treatise do not mitigate the novelty or the impact of the final theory, or the author’s firm conviction that his system was an accurate representation of physical , they indicate the scope of the work that lay ahead and that was effectively addressed in the next century when Kepler determined the ellipticity of planetary orbits, Gal
