Actual Motion
	Planetary objects, Small bodies, Gravity: -Position of an object can be described (K-4) -An object's motion can be described (K-4) -Change in motion is caused by pushing or pulling (K-4) -Light travels in a straight line (K-4) -Motion can be described from an objects position and direction and speed (5-8) -Objects in the solar system are in regular and predictable motion (5-8) -Gravity is the force that keeps objects in orbits around the sun and the rest of the motion in the solar system. (5-8) -Laws of motion can be calculated precisely by knowing the effects of forces on objects (9-12) -Objects in the universe are in motion and have been since the "big bang" (9-12)
