  1. Make a Name Tag Make a name tag (folded hotdog style) Personalize your name tag with symbols and pictures that represent you I will keep these on my cart every day They will be used to form groups/seating charts, to call on people, etc.

  2. Section 2.1(Assigned on Monday) Ancient Astronomy Development • Major driving force was practicality • Navigation • Seasons • Timekeeping • Ex. Stonehenge, Big Horn Medicine Wheel, Caracol Temple, Sundaggar, etc.

  3. Stonehenge3,000BC to 2,000BC • https://www.youtube.com/watch?v=-6oxmxPKoSE • https://www.youtube.com/watch?v=_n2QNHN72wA

  4. Unit 2.2(Assigned Tuesday) Cosmology- The science of the origin and development of the universe. Greeks • The universe did not go farther than the Solar System. – Earth, Sun, Moon • The model was literal to what we observe on Earth. • We do not feel the earth move, Sun looks like it is revolving around us, etc. • Geocentric- “Earth-centered”

  5. Geocentric Model • However, the planets did not move regularly. This model could not explain this phenomenon.

  6. Retrograde Motion • https://www.youtube.com/watch?v=kbynKfNfHk4 • Planet= Wanderer • Planets seem to form a loop, or “wander” in the sky

  7. Ptolemy’s- Geocentric Model • Accounted for Retrograde Motion with the use of “epicycles” • https://www.youtube.com/watch?v=utH-GHH1FT8

  8. Downfall of Ptolemy’s Model • The model was too complicated- • “In the physical sciences, simplicity has so often proved to be an indicator of truth.” • Example- telling a lie vs. telling the truth

  9. Section 2.3(assigned Wednesday) The Heliocentric Model- “Sun-centered”

  10. Nicolas Copernicus • Not the first person to think of the Heliocentric model (Aristarchus of Samos- 320BC), but refined the model • His heliocentric model was simpler than Ptolemy’s while still accounting for retrograde motion

  11. Copernicus-Retrograde Motion • If Earth moves faster than Mars in orbit, then Earth will eventually “overtakes” Mars. Mars will then appear to move backward • Examples? • https://www.youtube.com/watch?v=kbynKfNfHk4 • Apparent looping motions (vs. Real looping motions (Ptloemy)

  12. Copernican Revolution • “The critical realization that Earth is not at the center of our universe” - Text Book • Why is this a “critical realization?” • Not accepted for 200+ years • Not enough data to convince Catholic Church

  13. Copernican Revolution/Scientific Revolution • Tycho Brahe: • Collected VERY accurate Data • Johannes Kepler: • Assistant to Brahe: used data to develop laws of planetary motion • Franics Bacon: • Developed Scientific Method • Galileo Galili • First to use the telescope to study the stars, used observations to support Copernican Model
