  1. The Scientific Revolution Purple Textbook: Ch.6 Sec.1 Green Textbook: Ch. 1 Sec.5

  2. Main Idea • In the mid-1500s, scientists began to question accepted beliefs and make new theories based on experimentation

  3. Read • The Roots of Modern Science

  4. Geocentrism • People believed that the ______________________________________

  12. He stared at the sun SOOOO long…

  13. Problems with the Church • Scholars & church officials _________ Galileo’s discoveries • Church _____________ Copernicus’ work • can NOT be taught! • can NOT be read!

  14. Galileo’s Solution • Publish a book with both theories • Book: Debate “Geocentrism v. Heliocentrism” • Heliocentrism wins!

  15. Roman Inquisition • Galileo goes on trial (to court) • Forced to “admit” he & Copernicus were wrong (a lie…not true) • Sentenced to ____________________(forever) • He continued his work at home • Gravity (rate of speed)

  16. Experiments at Home • _______________ • Proved ALL objects on Earth fall at the same rate of speed

  17. Read • The Scientific Method
