Your work on ball down ramp has been received. Scroll down through the document to see any comments I might have inserted, and my final comment at the end.
Your general comment
Will a steeper ramp give greater or lesser time?
The steepest ramp will be the least because it will be rolling at a faster velocity.
As slopes increases will time intervals increase, decrease or show no pattern?
As the slope gets steeper the time intervals would decrease.

I was surprised because I think I just discovered that my house must be slanted. I'm on a perfectly level table but one side was much faster than the other.

Do your results support or fail to support your hypothesis about increasing or decreasing times?
The results support my hypothesis because as the slope got steeper the time intervals grew shorter and shorter.
How do you think ave velocity is related to slope?
As the ramp gets steeper this increases the average velocity of the ball because it increases the effect gravity has on the object.
Speculate on why ave velocity changes with slope.
Oh...Gravity is the cause of the velocity. But all the different slopes between level ground and free fall will gradually increase how fast anything moves.
How could you test your speculations?
I could measure the distance from the surface to where the ball was placed at the top of the ramp and then drop it from that height. The time would be much faster because gravity is having it's full effect on the free falling ball
Good data and good comments.
After the due date we will be discussing this experiment further via an online forum.
