=======Documenting Initial Knowledge about Motion=======
For the next diagnostic, we set up a ramp in the middle of the classroom for a ball to move down.\\
\\
As the ball moved down the ramp, Emily provided a commentary for the students:\\
  * The ball is moving at a constant, slow speed.\\
  * The ball begins to speed up as it moves down the ramp.\\
  * The ball continues to move at a fast pace until it suddenly stops.\\
\\
The students were to represent the motion in any way they could.\\
