Ch Discoveries and Inventions

* Understand the significance of the new scientific theories (e.g., those of Copernicus, Galileo, Kepler, Newton) and the significance of new inventions (e.g., the telescope, microscope, thermometer, barometer).

* The discovery of the Americas led to scholars to doubt ancient Greek ideas * Advances in astronomy were key events of the Scientific Revolution * Sir Isaac Newton developed laws that explained much of the natural world * New inventions helped scientists study the natural world

* During the Scientific Revolution, new ideas and inventions changed the nature of knowledge

* Nicolaus Copernicus * Tycho Brahe * Johannes Kepler * Galileo Galilei * Sir Isaac Newton * barometer

* Aristotle * Ptolemy

* If Ptolemy’s long-held beliefs were wrong, other Greek thinkers might be, too.

* Columbus’s discovery of the Americas

* No, because he didn’t realize that he hadn’t reached Asia

* Exploration led scholars to challenge the thoughts of the ancient Greeks

* Copernicus

* He was afraid of persecution or death at the hands of the church

* Copernicus thought that the planets’ orbits were circular * Kepler proved that the orbits are elliptical

* He charted the positions of the stars * He emphasized the importance of careful observations and detailed, accurate records

* He theorized that the planets orbited the sun

* The first scientist to study the sky with a telescope

* He was the first person to routinely use experiments to test theories

* He reviewed everything scientists had been learning, coupled it with his own observations and ideas, and identified four theories that explained how the physical world works

* He showed that light is made up of all the colors of the rainbow

* Gravity attracts objects to each other and thus keeps the planets in motion around the sun

* Sir Isaac Newton

* The laws explained how the physical world worked

* So that he could improve it

* Microscope * Thermometer * Telescope * Barometer

* Possible answer – the microscope or telescope because each allowed scientists to see into previously unseen worlds
