Before the BellEnter quietly
Pick up notebook from back of the room
Have a seat when the bell rings
Warm-Up“We’re about to go waaay back, back into time…”
(Anyone know what song this comes from?)1. Make a list of everything you did today that
probably wouldn’t have been possible in the 17th century (1600s)
2. How do you think scientists were able to make such remarkable observations given low technology?
3. If you did not have a telescope or map of space, etc. how could you calculate the sizes of planets?
Tips for SuccessCome to class on time and preparedTake notes in class!Pay attention during videos in class!Review powerpoints online!Review ALL worksheets & videos before an
exam (Study sheet, flash cards, Review game)

the past

Brain BreakWho are 5 famous people (dead or alive) you
would like to have a conversation with or hang out with?
Why did you choose these people?
Unit 3: History of AstronomyToday & Tomorrow: Ancient Astronomy
Lifestyles of the rich and the famous and their theories
Essential Questions:What was life like in ancient Greece?Who were these “famous” people?How did they develop knowledge of the
cosmos?What did they postulate?
Ancient Astronomy: COPYAstronomy is not the property of any one
culture, civilization or eraSame ideas, tools, and misconceptions have
been invented and reinvented by people all over the world
Astronomy born because people wanted to understand where we came from and how we fit into the cosmos
Ancient GreeceCollege/Career Prep Class: Read mini
article on Ancient Greece
As read underline or highlight important information that tells you what life was like in ancient Greece
Time: 10 min
Journal EntryIf time travel were possible, would you rather
live in ancient Greece or Charlotte in modern day?
Explain using details from the article and what you have experienced so far
Famous PeopleWill record notes on 5 people
ObservationsDiscuss:
How long would you have to observe the stars in order to determine the motion of the Sun?
How would you go about doing this without the aid of technology?
Observations _ Notes to CopyGreek astronomers observed the sky with the
naked eyeThroughout the night, they saw the stars
move across the skyOver the course of a month, they saw the
phases of the Moon change
Observations_Cont.Astronomers noticed the planets but were not
sure how they traveledTo the naked eye, planets vary in brightness
and do not remain in the same place in the sky
The planets seem to wander around the celestial sphere
The word planet derives from the Greek word planetes, meaning “wanderer”
Observations_Cont.Planets never stray from the ecliptic
Planets usually travel from East West
However, there is a time when the planet’s eastward motion stops and the planet appears to move westward before reversing again
Observations_Cont:Astronomers knew that the retrograde
motion was related to brightness of the planetThe challenge was to find a solar model that
explained the motion of all of the planetsThey hypothesized that the brightness is due
to the distance from earth
Could this be possible?
Quick WriteLetter to astronomers explaining if it is
possible for brightness to be related to distance from planets
What else could cause the brightness
Retrograde Animationhttp://projects.astro.illinois.edu/data/
Retrograde
Key VocabPrograde Motion- East West motion of
stars
Retrograde Motion- the “backward” loops of the planet
