Early Models of the Universe. Pythagoreans (500 B.C.) Believed the stars, planets, sun, and moon were attached to crystalline spheres which rotated around.

Presentation transcript:

The Original Science

In your science journal explain the concepts of a year, a month and a day. For each concept, illustrate the motion of Earth and the moon. Write a caption to describe each illustration.

Astronomy Objectives Identify units of a calendar Describe two early ideas about the structure of the universe Describe the contributions of Brahe, Kepler, Galileo, & Newton to modern astronomy Astronomy

Terms Astronomy Year Month Day

How would you tell the time or know what day it is without clocks & modern calendars?

People used seasonal cycles of the stars, planets & moon. How would you tell the time or know what day it is without clocks & modern calendars? People used seasonal cycles of the stars, planets & moon. Example: Farmer

Based on the observation of bodies in our solar system. Year Months (comes from the word moon) Day Use your textbook to write the definitions of each term. Page554-555

Claudius Ptolemy Ptolemaic Theory: An earth- centered universe.

Nicolaus Copernicus Copernican Theory: A sun- centered universe.

Johannes Kepler-Danish (Assistant of Brache) Tycho Brahe- Danish Recorded precise observations of the planets & stars. Johannes Kepler-Danish (Assistant of Brache) 3 laws of planetary motion Planets revolve around the sun in elliptical orbits

Galileo Galilei Isaac Newton-British Law of Gravity First to use a telescope to observe objects in space. Discoveries showed planets are not “wandering stars” Isaac Newton-British Law of Gravity Explained why all the planets orbit the most massive object in the solar system

Units of the modern calendar Ptolemaic Theory Copernican Theory
