ANALYZE IT

Complete Table A in your SDR then discuss it as a class.

Note: Questions marked with a triangle (∆) are included to enrich students’ understanding. These questions do not appear in your SDR but should be used as additional discussion points during the PostLab.

  • ∆ What caused a change in direction in the path of the planets or the Moon? 
  • ∆ What governs the movement of the planets around the Sun and the Moon around the Earth? 
  • ∆ What would occur if the planets and the Moon did not experience forward motion? What would occur if the Sun and the Earth did not exert the force of gravity on the planets and on the Moon? 

GET FOCUSED

Although the following Focus Question is not in your SDR for Investigation 3, you may discuss it with other students in class at this time. 

  • What causes the orbit of the planets around the Sun and the Moon around the Earth? 

Note: The Focus Question for Investigation Three and Four is the same. You will continue to explore the orbit of the planets in Investigation Four.
