What patterns can you find?

3. Use the patterns you discovered in the data and your knowledge of moon phases to answer these two questions.
What are the relative positions of Earth, Moon and Sun at the time of a solar eclipse?
What are the relative positions of Earth, Moon and Sun at the time of a lunar eclipse?

4. A closer look at Lunar Eclipses

8. Is the Moon’s orbit around Earth in the same plane as Earth’s orbit around the Sun?
When there is no lunar eclipse at the time of a full moon, where is the Moon in relation to Earth’s shadow?
Can we model the motion of the Moon to account for the phenomena?
