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 for the ball to travel down three ramps with increasing steepness will decrease for each ramp.
As slopes increases will time intervals increase, decrease or show no pattern?
If we write the slopes from the least to the greatest the time intervals will decrease as the slopes increase in steepness.

During the process of practicing I was concentrating on making sure that I started and stopped the timer at the correct times.
During performing the trails I tried to make sure I was doing as I did while practicing.

Do your results support or fail to support your hypothesis about increasing or decreasing times?
The result that I recieved from the experiment supports the hypothesis that I stated. Each time I add a dominoe to raise the ramp the time for the ball to travel the length of the ramp decreased.
How do you think ave velocity is related to slope?
The average velocity of the ball increased as the slope of the ramp increased. This is apparent when the ball hits the metal bracket at the end of the ramp. The metal bracket moves backwards as the ball strikes it. The higher the ramp the further the metal bracket moved. This is due because the ball has a greater velocity due to the steepness of the ramp.
Speculate on why ave velocity changes with slope.
The average velocity of the ball is caused b the mass of the ball and the increased speed as the slope of the ramp increases.
How could you test your speculations?
By changing the size of the ball used.
