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?
Interval on the steepest ramp would be the least because the ball will roll faster on this slope.
As slopes increases will time intervals increase, decrease or show no pattern?
The time intervals are going to be decreasing from least slope to greatest slope.

Do your results support or fail to support your hypothesis about increasing or decreasing times?
I think the imperfections on the board caused inaccurate results when I put the dominoes under the right side. The trials I did on the left side did conclude that my hypothesis is true. I think human error in this experiment causes some imperfect results.
How do you think ave velocity is related to slope?
The average velocity of the ball increases as the slope increases and decreases as the slop decreases.
Speculate on why ave velocity changes with slope.
It is only natural that a ball will roll faster on a steeper slope. Gravity is going to be pulling faster on the ball that is coming down a steep slope.
How could you test your speculations?
Just as we did. Trial tests and comparing the data of the different slop levels to see the correlation.
Your data look good.
After the due date we will be discussing this experiment further via an online forum.
