5. Geo means _______________, so in the geocentric model of the universe,
_________________ is the center of the solar system and everything else
________________ around it.
6. The ___________________ model puts the sun at the center of the solar system.
7. True or False (circle)
At the present time, scientists use a geocentric model.

8. Matching
_____Aristotle
a. thought planets traveled on a separate circular path
as they revolved around Earth
_____Aristarchus
b. used Venus’s phases as a reason why planets
orbited the Sun rather than Earth
_____Ptolemy
c. had complete mathematical explanations for the
heliocentric model
_____Copernicus
d. said Earth couldn’t be moving since we didn’t feel it
_____ Kepler
e. created 3 laws of planetary motion
_____Galileo
f. figured out Sun was larger than Earth so it would
make more sense for Earth to revolve around Sun
Slide 5
9. Why did scientists long ago create incorrect hypotheses of the solar system?
_________________________________________________________________
10. True or False (circle) The solar system has changed over time, which is why
the models of the solar system have changed, too.
Slide 6
11. True or False (circle) A star seems to have 2 different backgrounds when
viewed months apart because it is viewed in different
locations of Earth’s orbit.
