Describe the movements of the Sun, Moon and Earth in our Solar System.

The Sun is at the center of the Solar System. The Earth revolves around the Sun while rotating on its axis. The moon rotates and revolves around the Earth.

Use Newton's First Law of Motion to describe what will happen to a scooter being pushed forward on a gym floor.

Newton's First Law of Motion states that an object in a state of motion will stay in that state until a force acts upon it. The scooter will move forward in a straight path. The force of gravity will work against this forward motion which will cause the scooter to slow and halt its forward motion.
