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 required to roll the length of the ramp will be least for the steepest ramp.
As slopes increases will time intervals increase, decrease or show no pattern?
The time intervals would be increasing.

I was thinking that the ball is moving relatively slow in this forst trial.

Do your results support or fail to support your hypothesis about increasing or decreasing times?
My results support the hypothesis that time required to roll the length of the ramp will be the least for the steepest ramp.
How do you think ave velocity is related to slope?
The increased slope of the ball causes the ball to accelerate at a faster rate which increases velocity, therefore decreasing time.
Speculate on why ave velocity changes with slope.
Acceleration causes the average velocity to change with slope.
How could you test your speculations?
I could conduct more trials.
You have good data and clear answers to questions.
After the due date we will be discussing this experiment further via an online forum.
