Your 'ball down ramp' report 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? **
time to roll down should be least for the steepest ramp
** As slopes increases will time intervals increase, decrease or show no pattern? **
the time intervals in this case would be decreasing

the first 5 lines are the time the ball rolled down the ramp lifted by only one domino from right to left (in seconds), the next five numbers are how long it took to roll from left to right. i clicked the timer when i released the ball and then again when it struck the bracket at the end of the ramp, 27 cm away

** Do your results support or fail to support your hypothesis about increasing or decreasing times? **
the results support my hypothesis
** How do you think ave velocity is related to slope? **
velocity increases as the slope increases
** Speculate on why ave velocity changes with slope. **
gravity works to help the velocity when the slope is greater because the ball is allowed to go more downhill with a greater slope and has to go more side to side with a lesser slope. gravity helps things go down of course
** How could you test your speculations? **
further testing with different objects
You need to be specific about how you would test this. Please submit a good statement explaining how you would design an experiment to test this hypothesis.
