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 time interval will be least for the steepest ramp.
As slopes increases will time intervals increase, decrease or show no pattern?
I would expect the time interval to be decreasing.

I was thinking why such the change in speed from the domino being moved from the right to left side.

Do your results support or fail to support your hypothesis about increasing or decreasing times?
No, my hypotheses is correct. The more dominoes placed under the ramp, the shorter the time intervals became.
How do you think ave velocity is related to slope?
The average velocity of the ball is greater when the ramp is at a steeper incline. The ball travels faster when placed on the steeper ramp.
Speculate on why ave velocity changes with slope.
Gravity. The higher up an object is the faster it will fall. With one domino it took much longer for the ball to gain speed than it did with three.
How could you test your speculations?
By continuing to place more dominoes under the ramp to show that the more dominoes under the ramp the shorter each time interval will become
Your data look good.
After the due date we will be discussing this experiment further via an online forum.
