    Problem  - How will the size of a sphere affect the time of the sphere when it falls?
    Hypothesis - My hypothesis is that  the heavier the marble or ball the faster the marble will drop.
    Experiment  - We will drop the spheres and graph the times to get the results
    Procedure
  1.  First we will gather all of our materials.
  2. We grab the timer.
  3. We will drop the spheres and start the timer so we can measure the time.
  4.  We will repeat steps 2-3 ten more times so we can get the rest of the times.
  5. Finally we will clean our materials up.
  6. Materials
  7. Marble
  8. Ping Pong ball
  9. Basketball
  10. Timer
  11. CV- Where the object falls from.
  12. IV-  The size of the sphere, weight of the object.
  13. DV- Time it takes for the object to fall to the ground.
  14. Observations My observations were that the spear would fall
    Conclusion  My conclusion is that the heavier the sphere is the faster the object will fall.
