  1. Scientific Revolution Please pick up and complete a Reading Study Guide! A Revolution in Understanding

  2. Please read the below scenario and answer the questions • You have two objects, one weighs 4 lbs and the other weighs ½ lb. • You then drop both objects from 7 feet above the ground. • Which object will strike the ground first? • Explain why you believe that? • Design an experiment to prove your hypothesis.

  3. Objectives • Compare and contrast geocentric and heliocentric theories • Describe the scientific method • Describe the contribution to science of: • Copernicus • Galileo • Bacon / Descartes • Newton

  4. Medieval View • Earth-centered view • “Geo-centric” • Taught through ancient writings of Aristotle • Supported by the church

  5. Nicolaus Copernicus • Polish cleric • Studied the movement of planets

  6. Heliocentric Theory • Sun centered view • Planets revolved around the sun • Proven mathematically

  7. Nicolaus Copernicus • Polish cleric • Studied the movement of planets • Heliocentric theory • Published his findings in 1543 (last year of his life) • His student was Galileo

  8. Scientific Method • Question • Hypothesis • Experiment • Conclusion

  9. Galileo Galilei • Italian scientist • Observed common events • Asked Questions • Made amazing discoveries!

  10. Motion experiments - Dropping objects • Objects of different weights fall at the same speed

  11. Built one of the first telescopes • Observed the planets • Jupiter's moons • Supported Copernicus’s ideas

  12. Conflict with the Church • Galileo’s discoveries supported Copernicus • Differed from church teachings • Arrested and tried by the Pope (1633) • Confessed to being wrong…

  13. “With sincere heart and unpretended faith I abjure, curse and detest the aforesaid errors and heresies (of Copernicus) and also every other error…contrary to the Holy Church…”

  14. “But it does move!”

  15. Galileo Falls to the Church Please have your homework out… • Answer these questions on your own paper. (see your homework, question/section 2) • Why did Galileo’s findings anger the church? • What was Galileo forced to do? Describe. • Describe how the interest in science led to a new approach called the Scientific method.

  16. Isaac NewtonLaw of Gravity • Describe the heliocentric theory • Describe the geocentric theory. • Explain how gravity works? Why do things get pulled toward the earth?

  17. Law of Gravity: Isaac Newton • English • Studied Physics • How objects move • Discovered why gravity works • Every object attracts other objects • This attraction depends on: • Mass of the objects • Distance apart Newton Law of Gravity Published in 1687 Gravity

  18. What was revolutionary about the Scientific Revolution? • New interest in science led people to ask questions • Needed a standard method to prove the answer • 2 scientists developed a new way to prove • Used a logical approach to science • observation and test • Used mathematics and logic • Applied to thinking • The new ‘approach’ called a ‘method’ Questions, testing, proof Francis Bacon Rene Descartes Scientific Method

  19. Geocentric and Heliocentric • 1. Divide your paper in ½ • On one side draw the geocentric theory • On the other, draw the heliocentric theory • 2. Next to each drawing, list 3 people or terms associated with each theory (i.e. Aristotle = geocentric)
