Your general comment

Here's number 3.

Will a steeper ramp give greater or lesser time?

I believe as the ramp becomes steeper speed will increase and time will decrease.

As slopes increases will time intervals increase, decrease or show no pattern?

Time intervals should decrease.

Your report of 5 trials each way for 1 domino

It rolled 27cm.

Your report of 5 trials each way for 2 dominoes

I was trying to focus on making sure I was doing it the same each time. I was also wondering if the table was completely level and if that affected my numbers when I did the experiment going from left to right or was there something else? (I don't think so... I'm sure it was the table.)

Do your results support or fail to support your hypothesis about increasing or decreasing times?

Nope. They support it. The more slope increases, the more speed increases, thus time is decreased. You can see this as the dominoes were added.

How do you think ave velocity is related to slope?

Velocity increases as slope increases because of gravity pulling on the ball and the route that the ball can be pulled to the ground. As the slope increases the route as to which the ball can be pulled to the ground becomes easier for the ball to travel.

Speculate on why ave velocity changes with slope.

I think I already explained that in the last statement.

How could you test your speculations?

By repeating this type of experiment many times over and seeing the the data was similar.
