15 8 Lesson 6.9 Lesson Plan Ends with Mars has a much smaller mass than Earth. If Mars were the same distance from the Sun as the Earth is, how would the gravitational force between Mars and the Sun compare to the gravitational force between Earth and the Sun? Add after the previous question: Why isn’t there a solar eclipse every month as the moon passes between the Earth and the Sun? A full model of the relationship among Earth, Sun, and Moon must explain the pattern of orbital interactions that cause eclipses to occur. 16 8 Lesson 6.11 Teacher Tips The model activity is designed to get students to understand that Earth’s tilt during its revolution around the Sun is the reason for the seasons. Add (at the end of the paragraph) The model activity is also designed to get students to understand that the moon’s orbital plane is not aligned to Earth’s orbit around the sun. A full model of the Earth’s annual path around the Sun needs to include an understanding of the moon’s orbital behavior, too.
