Review sheet items
Unit 8
 Describe how Eratosthenes determined the
size of the Earth.
 Explain how we can determine the size of
the moon relative to that of the Earth.
 How do we determine the distance to and
size of the Sun relative to that of the Earth?
What part of this process is most prone to
error?
Unit 9
 Describe the three philosophical assumption
behind Ptolemy’s model.
 Describe Ptolemy’s model of the solar
system and the evidence it had to support.
 Explain retrograde motion of planets in
terms of Ptolemaic and heliocentric models.
Unit 10
 Describe Kepler’s three laws. To what do
they apply?
 Describe Newton’s three laws. What does
the force of gravity depend on?
 Explain how Kepler used Tycho’s data to
determine the orbit of Mars.
Unit 11
 Describe the evidence Galileo discovered
that supported a heliocentric model.
 The fact that Venus exhibits all phases
supports which model of the solar system?
